Vaccines for Travelers

Vaccines protect travelers from serious diseases. Depending on where you travel, you may come into contact with diseases that are rare in the United States, like yellow fever. Some vaccines may also be required for you to travel to certain places.

Getting vaccinated will help keep you safe and healthy while you’re traveling. It will also help make sure that you don’t bring any serious diseases home to your family, friends, and community.

On this page, you'll find answers to common questions about vaccines for travelers.

Which vaccines do I need before traveling?

The vaccines you need to get before traveling will depend on few things, including:

• Where you plan to travel . Some countries require proof of vaccination for certain diseases, like yellow fever or polio. And traveling in developing countries and rural areas may bring you into contact with more diseases, which means you might need more vaccines before you visit.
• Your health . If you’re pregnant or have an ongoing illness or weakened immune system, you may need additional vaccines.
• The vaccinations you’ve already had . It’s important to be up to date on your routine vaccinations. While diseases like measles are rare in the United States, they are more common in other countries. Learn more about routine vaccines for specific age groups .

How far in advance should I get vaccinated before traveling?

It’s important to get vaccinated at least 4 to 6 weeks before you travel. This will give the vaccines time to start working, so you’re protected while you’re traveling. It will also usually make sure there’s enough time for you to get vaccines that require more than 1 dose.

Where can I go to get travel vaccines?

Start by finding a:

• Travel clinic
• Health department
• Yellow fever vaccination clinic

Cdc says travel is safe for fully vaccinated people, but opposes nonessential trips.

The Centers for Disease Control and Prevention updated its domestic travel guidance for fully vaccinated people on Friday, lifting certain requirements while continuing to advise mitigation measures like mask-wearing and hand-washing.

The Centers for Disease Control and Prevention has updated its domestic travel guidance for fully vaccinated people, lifting certain testing and self-quarantine requirements and recommending precautions like wearing a mask and avoiding crowds. But health officials continue to discourage nonessential travel, citing a sustained rise in cases and hospitalizations.

The CDC updated its website on Friday to reflect the latest scientific evidence, writing that "people who are fully vaccinated with an FDA-authorized vaccine can travel safely within the United States."

The announcement comes less than a month after the CDC first released updated guidance about gatherings for fully vaccinated people, which it described as a "first step" toward returning to everyday activities.

Air Travel Is Opening Up Again, But That Doesn't Mean The Pandemic Is Over

The CDC considers someone fully vaccinated two weeks after they receive the last dose of vaccine. Those individuals will no longer need to get tested before or after travel unless their destination requires it, and do not need to self-quarantine upon return.

The new guidance means, for example, that fully vaccinated grandparents can fly to visit their healthy grandkids without getting a COVID-19 test or self-quarantining as long as they follow other recommended measures while traveling, according to CDC Director Rochelle Walensky.

Those measures include wearing a mask over their nose and mouth, staying 6 feet from others and washing their hands frequently. Masks are required on all planes traveling into, within or out of the U.S., under an executive order issued by President Biden.

But Walensky, speaking at a White House COVID-19 Response Team briefing on Friday, nonetheless discouraged all nonessential travel, citing a continued increase in the seven-day average of cases and hospitalizations.

"While we believe that fully vaccinated people can travel at low risk to themselves, CDC is not recommending travel at this time due to the rising number of cases," Walensky said.

CDC Director Fears 'Impending Doom' If U.S. Opens Too Quickly

She said that while vaccinated people can do more things safely, most Americans are not yet fully vaccinated. Those who are not must have a negative test 1-3 days before they travel under CDC guidance. They must either get tested 3-5 days after they return and self-quarantine for 7 days, or self-quarantine for 10 days with no test.

Walensky said on Monday that there is more travel occurring now than throughout the pandemic, including the winter holidays. She acknowledged that people have been looking to get away over spring break or take advantage of what they perceive as a "relative paucity in cases," and she said the country was seeing an uptick in cases as a result.

"The thing that's different this time is that we actually have it in our power to be done with the scale of the vaccination," she said. "And that will be so much slower if we have another surge to deal with as well."

The U.S. is already seeing an uptick in domestic travel, and many Americans are looking to book trips in the coming months in what experts described to NPR as a sign of "clear pent up demand for travel."

As the country's supply of COVID-19 doses has grown, so has Biden's goal for the number of shots in arms during his first 100 days, doubling the target to 200 million by the end of this month. Many states have already expanded eligibility to all adults or are set to do so in the coming weeks, well ahead of the president's May 1 deadline.

According to NPR's vaccine tracker , 16.9% of the U.S. population is fully vaccinated, and 30% has had at least one dose. Researchers estimate that 70% to 85% of the country would need to have immunity for COVID-19 to stop spreading through communities.

International travel restrictions remain

The CDC is not lifting travel restrictions barring the entry of most non-U.S. citizens from places including China, Brazil, South Africa and parts of Europe. It will continue to require airline passengers entering the U.S. to get a test within three days of their departure and show proof of a negative result before boarding.

The travel industry has been pushing for some of these restrictions to end. A group of 26 organizations sent a letter to White House COVID-19 czar Jeffrey Zients urging the federal government "to partner with us to develop, by May 1, 2021, a risk-based, data-driven roadmap to rescind inbound international travel restrictions."

While Some Spring Breakers Swarm Beaches, Many Stay Home, Dreaming Of Summer Travel

"To be clear, at this time, we do not support removal or easing of core public health protections, such as the universal mask mandate, inbound international testing requirement, physical distancing or other measures that have made travel safer and reduced transmission of the virus," they wrote. "However, the data and science demonstrate that the right public health measures are now in place to effectively mitigate risk and allow for the safe removal of entry restrictions."

Travel and tourism have taken a considerable hit because of the pandemic with industry groups noting that overseas travel to the U.S. declined by 81% in 2020, causing billions of dollars in losses. Without lifting international travel bans, the U.S. Travel Association estimates that some 1.1 million American jobs will not be restored and billions in spending will be lost by the end of the year.

"Fortunately, enough progress has been made on the health front that a rebound for domestic leisure travel looks possible this year, but that alone won't get the job done," Roger Dow, the association's president and CEO, said in a statement . "A full travel recovery will depend on reopening international markets, and we must also contend with the challenge of reviving business travel."

Which Vaccinations Are Required for Travel?

By Cassie Shortsleeve

A trip abroad requires you to be up-to-date on a whole checklist of things these days: travel insurance, airline policies, visas, passports , and, as far as your health is concerned, vaccines. Yet while the COVID-19 pandemic has made us acutely aware of the importance of staying healthy on the road, travel vaccines have always been a mainstay of safe travel—a crucial tool in avoiding the (often expensive) headaches of getting sick , and treating sicknesses, abroad.

Whether you have travel on the horizon or want to be prepared for 2023 trips and beyond, this guide will get you up to speed on the vaccinations required for travel depending on your destination, itinerary, and health status. Follow the below steps to protect your immune system in another country.

Make sure you’re current with routine vaccines

The Centers for Disease Control and Prevention (CDC) recommends all travelers be up to date on routine vaccines before travel. Routine vaccines include shots like COVID-19; chickenpox; Hepatitis A and B; Influenza; Measles, Mumps, Rubella (MMR); Polio; and more. The CDC has a full list of routine vaccines here .

“‘Routinely recommended vaccines’ are vaccines that have been considered very important to prevent common diseases in the population to start,” says Lin H. Chen , M.D. director of the Travel Medicine Center at Mount Auburn Hospital in Cambridge, Massachusetts, and the former president of the International Society of Travel Medicine (ISTM).

Routine vaccines protect against disease that exists at low levels (chickenpox) or barely exists at all (measles) in the U.S. They also protect against severe disease from diseases that are still present in the United States (influenza or COVID-19). Generally, they’re given in childhood or adolescence—though some are given through adulthood—so it’s always a good idea to double-check your vaccination records.

When traveling, routine shots are especially important because international travel increases your chances of both contracting and spreading diseases that aren’t common in the U.S. A good example of this is measles. While it’s practically non-existent in the U.S., international travel increases your risk of exposure and popular destinations including Europe still have measles outbreaks.

It’s worth double checking your status even if you think you’re up to date: “During the pandemic, some routine vaccination programs may have suffered lapses, so there is concern that diseases may become more common,” says Dr. Chen.

The routine vaccination recommendations have also changed over the years (the addition of the COVID-19 vaccine to the list is an example) and it’s easy to let vaccines like tetanus ( generally needed every 10 years ) lapse.

“It is even recommended at this time that certain adults who are traveling who have not had a polio vaccine for many years and are traveling to a risk area get an additional dose of the polio vaccine,” says Elizabeth D. Barnett , M.D., a professor at Boston University Medical School and a leader in the field of travel and tropical Medicine.

If you’re traveling with a child , talk to your pediatrician: Rules around vaccination can be different for babies traveling internationally. A baby who is not leaving the U.S., for example, gets their first dose of the MMR vaccine at 12 months; if they will be leaving the country, they get the first dose at six months .

Utilize official resources to learn more about vaccination recommendations around the world

“Understanding the epidemiology of where diseases are circulating is really important,” says Dr. Chen.

That’s why, generally, she sends travelers to the CDC’s website , which outlines exactly what additional vaccines you may need for essentially every country in the world. All you have to do is plug in your destination and you’ll find information about vaccines and medications, health travel notices, COVID-19 travel information, and more.

Start a conversation with your primary care doctor—then consider seeing a travel medicine specialist

It’s always good to start a conversation with your primary care doctor about vaccines before you travel, but if your itinerary is complex, involving multiple countries, being in rural areas, areas without good hygiene, or areas where you may not be able to protect yourself from mosquito- or food-borne illnesses, or if you have questions based on what you found on the CDC website or your own personal health history, consider asking your physician for a referral to a travel medicine specialist or travel clinic.

After all, when it comes to vaccinations required for travel, it’s not just about where you travel, but how you travel.

“The art of travel medicine is listening to where the person is going, what they're going to be doing, and making a decision based on the risk-benefit ratio,” says Dr. Barnett. A travel medicine doctor will be able to analyze disease trends and trip details such as how long you’ll be traveling or how well you’ll be able to protect yourself against mosquitoes. “You have to really dig into those things,” she says.

Take a vaccine called the Japanese encephalitis vaccine, which prevents a type of encephalitis (inflammation of the brain). “We can't just say the risk is present in a specific country, because the risk depends on the time of year, whether the disease is being transmitted at that time, the exact location—rural areas, especially farming regions are associated with much higher risk — whether there's a local outbreak situation going on, and more.”

You may not be able to get every shot you need at your primary care doctor’s office either. The yellow fever vaccine, for example (which you may need if you’re traveling somewhere like Sub-Saharan Africa or specific parts of South America), is only available at special travel clinics or public health settings, says Dr. Barnett. You can find a list of travel medicine clinics on the CDC’s website.

Your health background (what diseases you’ve had in the past, whether or not you’re immune-suppressed, and if you’re more predisposed to a certain condition) also play a role in what vaccines to consider. (A very small subset of people vaccinated against yellow fever, for example, experience severe adverse events, says Dr. Barnett.)

The bottom line

For many people and many trips, discussing travel plans with your primary care doctor and using the CDC’s destination feature for vaccine guidance will suffice. Other, more complex trips require a visit to a travel clinic. If you’re aiming to get into one, start the process at least a month before your departure date—appointments can be hard to get and your body needs time to build up immunity from any additional vaccines you may require.

Travelers more likely to encounter rabid animals include

• Campers, adventure travelers, or cave explorers (spelunkers)
• Veterinarians, animal handlers, field biologists, or laboratory workers handling animal specimens
• Visitors to rural areas

Since children are more likely to be bitten or scratched by a dog or other animals, consider rabies vaccination for children traveling to Mexico. 

Rabies - CDC Yellow Book

Recommended for most travelers, especially those staying with friends or relatives or visiting smaller cities or rural areas.

Typhoid - CDC Yellow Book

Learn actions you can take to stay healthy and safe on your trip. Vaccines cannot protect you from many diseases in Mexico, so your behaviors are important.

Eat and drink safely

Food and water standards around the world vary based on the destination. Standards may also differ within a country and risk may change depending on activity type (e.g., hiking versus business trip). You can learn more about safe food and drink choices when traveling by accessing the resources below.

• Choose Safe Food and Drinks When Traveling
• Water Treatment Options When Hiking, Camping or Traveling
• Global Water, Sanitation and Hygiene | Healthy Water
• Avoid Contaminated Water During Travel

You can also visit the Department of State Country Information Pages for additional information about food and water safety.

Prevent bug bites

Bugs (like mosquitoes, ticks, and fleas) can spread a number of diseases in Mexico. Many of these diseases cannot be prevented with a vaccine or medicine. You can reduce your risk by taking steps to prevent bug bites.

What can I do to prevent bug bites?

• Cover exposed skin by wearing long-sleeved shirts, long pants, and hats.
• Use an appropriate insect repellent (see below).
• Use permethrin-treated clothing and gear (such as boots, pants, socks, and tents). Do not use permethrin directly on skin.
• Stay and sleep in air-conditioned or screened rooms.
• Use a bed net if the area where you are sleeping is exposed to the outdoors.

What type of insect repellent should I use?

• FOR PROTECTION AGAINST TICKS AND MOSQUITOES: Use a repellent that contains 20% or more DEET for protection that lasts up to several hours.
• Picaridin (also known as KBR 3023, Bayrepel, and icaridin)
• Oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD)
• 2-undecanone
• Always use insect repellent as directed.

What should I do if I am bitten by bugs?

• Avoid scratching bug bites, and apply hydrocortisone cream or calamine lotion to reduce the itching.
• Check your entire body for ticks after outdoor activity. Be sure to remove ticks properly.

What can I do to avoid bed bugs?

Although bed bugs do not carry disease, they are an annoyance. See our information page about avoiding bug bites for some easy tips to avoid them. For more information on bed bugs, see Bed Bugs .

For more detailed information on avoiding bug bites, see Avoid Bug Bites .

Some diseases in Mexico—such as dengue, Zika, leishmaniasis, and Chagas disease—are spread by bugs and cannot be prevented with a vaccine. Follow the insect avoidance measures described above to prevent these and other illnesses.

Stay safe outdoors

If your travel plans in Mexico include outdoor activities, take these steps to stay safe and healthy during your trip.

• Stay alert to changing weather conditions and adjust your plans if conditions become unsafe.
• Prepare for activities by wearing the right clothes and packing protective items, such as bug spray, sunscreen, and a basic first aid kit.
• Consider learning basic first aid and CPR before travel. Bring a travel health kit with items appropriate for your activities.
• If you are outside for many hours in heat, eat salty snacks and drink water to stay hydrated and replace salt lost through sweating.
• Protect yourself from UV radiation : use sunscreen with an SPF of at least 15, wear protective clothing, and seek shade during the hottest time of day (10 a.m.–4 p.m.).
• Be especially careful during summer months and at high elevation. Because sunlight reflects off snow, sand, and water, sun exposure may be increased during activities like skiing, swimming, and sailing.
• Very cold temperatures can be dangerous. Dress in layers and cover heads, hands, and feet properly if you are visiting a cold location.

Stay safe around water

• Swim only in designated swimming areas. Obey lifeguards and warning flags on beaches.
• Practice safe boating—follow all boating safety laws, do not drink alcohol if driving a boat, and always wear a life jacket.
• Do not dive into shallow water.
• Do not swim in freshwater in developing areas or where sanitation is poor.
• Avoid swallowing water when swimming. Untreated water can carry germs that make you sick.
• To prevent infections, wear shoes on beaches where there may be animal waste.

Leptospirosis, a bacterial infection that can be spread in fresh water, is found in Mexico. Avoid swimming in fresh, unchlorinated water, such as lakes, ponds, or rivers.

Keep away from animals

Most animals avoid people, but they may attack if they feel threatened, are protecting their young or territory, or if they are injured or ill. Animal bites and scratches can lead to serious diseases such as rabies.

Follow these tips to protect yourself:

• Do not touch or feed any animals you do not know.
• Do not allow animals to lick open wounds, and do not get animal saliva in your eyes or mouth.
• Avoid rodents and their urine and feces.
• Traveling pets should be supervised closely and not allowed to come in contact with local animals.
• If you wake in a room with a bat, seek medical care immediately. Bat bites may be hard to see.

All animals can pose a threat, but be extra careful around dogs, bats, monkeys, sea animals such as jellyfish, and snakes. If you are bitten or scratched by an animal, immediately:

• Wash the wound with soap and clean water.
• Go to a doctor right away.
• Tell your doctor about your injury when you get back to the United States.

Consider buying medical evacuation insurance. Rabies is a deadly disease that must be treated quickly, and treatment may not be available in some countries.

Reduce your exposure to germs

Follow these tips to avoid getting sick or spreading illness to others while traveling:

• Wash your hands often, especially before eating.
• If soap and water aren’t available, clean hands with hand sanitizer (containing at least 60% alcohol).
• Don’t touch your eyes, nose, or mouth. If you need to touch your face, make sure your hands are clean.
• Cover your mouth and nose with a tissue or your sleeve (not your hands) when coughing or sneezing.
• Try to avoid contact with people who are sick.
• If you are sick, stay home or in your hotel room, unless you need medical care.

Avoid sharing body fluids

Diseases can be spread through body fluids, such as saliva, blood, vomit, and semen.

Protect yourself:

• Use latex condoms correctly.
• Do not inject drugs.
• Limit alcohol consumption. People take more risks when intoxicated.
• Do not share needles or any devices that can break the skin. That includes needles for tattoos, piercings, and acupuncture.
• If you receive medical or dental care, make sure the equipment is disinfected or sanitized.

Know how to get medical care while traveling

Plan for how you will get health care during your trip, should the need arise:

• Carry a list of local doctors and hospitals at your destination.
• Review your health insurance plan to determine what medical services it would cover during your trip. Consider purchasing travel health and medical evacuation insurance.
• Carry a card that identifies, in the local language, your blood type, chronic conditions or serious allergies, and the generic names of any medications you take.
• Some prescription drugs may be illegal in other countries. Call Mexico’s embassy to verify that all of your prescription(s) are legal to bring with you.
• Bring all the medicines (including over-the-counter medicines) you think you might need during your trip, including extra in case of travel delays. Ask your doctor to help you get prescriptions filled early if you need to.

Many foreign hospitals and clinics are accredited by the Joint Commission International. A list of accredited facilities is available at their website ( www.jointcommissioninternational.org ).

In some countries, medicine (prescription and over-the-counter) may be substandard or counterfeit. Bring the medicines you will need from the United States to avoid having to buy them at your destination.

Malaria is a risk in some parts of Mexico. If you are going to a risk area, fill your malaria prescription before you leave, and take enough with you for the entire length of your trip. Follow your doctor’s instructions for taking the pills; some need to be started before you leave.

Select safe transportation

Motor vehicle crashes are the #1 killer of healthy US citizens in foreign countries.

In many places cars, buses, large trucks, rickshaws, bikes, people on foot, and even animals share the same lanes of traffic, increasing the risk for crashes.

Be smart when you are traveling on foot.

• Use sidewalks and marked crosswalks.
• Pay attention to the traffic around you, especially in crowded areas.
• Remember, people on foot do not always have the right of way in other countries.

Riding/Driving

Choose a safe vehicle.

• Choose official taxis or public transportation, such as trains and buses.
• Ride only in cars that have seatbelts.
• Avoid overcrowded, overloaded, top-heavy buses and minivans.
• Avoid riding on motorcycles or motorbikes, especially motorbike taxis. (Many crashes are caused by inexperienced motorbike drivers.)
• Choose newer vehicles—they may have more safety features, such as airbags, and be more reliable.
• Choose larger vehicles, which may provide more protection in crashes.

Think about the driver.

• Do not drive after drinking alcohol or ride with someone who has been drinking.
• Consider hiring a licensed, trained driver familiar with the area.
• Arrange payment before departing.

Follow basic safety tips.

• Wear a seatbelt at all times.
• Sit in the back seat of cars and taxis.
• When on motorbikes or bicycles, always wear a helmet. (Bring a helmet from home, if needed.)
• Avoid driving at night; street lighting in certain parts of Mexico may be poor.
• Do not use a cell phone or text while driving (illegal in many countries).
• Travel during daylight hours only, especially in rural areas.
• If you choose to drive a vehicle in Mexico, learn the local traffic laws and have the proper paperwork.
• Get any driving permits and insurance you may need. Get an International Driving Permit (IDP). Carry the IDP and a US-issued driver's license at all times.
• Check with your auto insurance policy's international coverage, and get more coverage if needed. Make sure you have liability insurance.
• Avoid using local, unscheduled aircraft.
• If possible, fly on larger planes (more than 30 seats); larger airplanes are more likely to have regular safety inspections.
• Try to schedule flights during daylight hours and in good weather.

Medical Evacuation Insurance

If you are seriously injured, emergency care may not be available or may not meet US standards. Trauma care centers are uncommon outside urban areas. Having medical evacuation insurance can be helpful for these reasons.

Maintain personal security

Use the same common sense traveling overseas that you would at home, and always stay alert and aware of your surroundings.

Before you leave

• Research your destination(s), including local laws, customs, and culture.
• Monitor travel advisories and alerts and read travel tips from the US Department of State.
• Enroll in the Smart Traveler Enrollment Program (STEP) .
• Leave a copy of your itinerary, contact information, credit cards, and passport with someone at home.
• Pack as light as possible, and leave at home any item you could not replace.

While at your destination(s)

• Carry contact information for the nearest US embassy or consulate .
• Carry a photocopy of your passport and entry stamp; leave the actual passport securely in your hotel.
• Follow all local laws and social customs.
• Do not wear expensive clothing or jewelry.
• Always keep hotel doors locked, and store valuables in secure areas.
• If possible, choose hotel rooms between the 2nd and 6th floors.

To call for emergency services while in Mexico, dial 066, 060, or 080. Write these numbers down to carry with you during your trip.

Learn as much as you can about Mexico before you travel there. A good place to start is the country-specific information on Mexico from the US Department of State.

Americans in Mexico have been arrested for purchasing souvenirs that were, or looked like, antiques and that local customs authorities believed were national treasures. Familiarize yourself with any local regulations for antiques and follow these tips:

• When you are considering purchasing an authentic antique or a reproduction, ask if you are allowed to export these items before you purchase them.

Healthy Travel Packing List

Use the Healthy Travel Packing List for Mexico for a list of health-related items to consider packing for your trip. Talk to your doctor about which items are most important for you.

Why does CDC recommend packing these health-related items?

It’s best to be prepared to prevent and treat common illnesses and injuries. Some supplies and medicines may be difficult to find at your destination, may have different names, or may have different ingredients than what you normally use.

If you are not feeling well after your trip, you may need to see a doctor. If you need help finding a travel medicine specialist, see Find a Clinic . Be sure to tell your doctor about your travel, including where you went and what you did on your trip. Also tell your doctor if you were bitten or scratched by an animal while traveling.

If your doctor prescribed antimalarial medicine for your trip, keep taking the rest of your pills after you return home. If you stop taking your medicine too soon, you could still get sick.

Malaria is always a serious disease and may be a deadly illness. If you become ill with a fever either while traveling in a malaria-risk area or after you return home (for up to 1 year), you should seek immediate medical attention and should tell the doctor about your travel history.

What to Know About the C.D.C. Guidelines on Vaccinated Travel

In updated recommendations, the federal health agency said both domestic and international travel was low risk for fully vaccinated Americans. But travel remains far from simple.

• Share full article

By Ceylan Yeginsu

The Centers for Disease Control and Prevention updated its guidance for fully vaccinated Americans in April, saying that traveling both domestically and internationally was low risk.

The long-awaited recommendations were issued by federal health officials after a series of studies found that vaccines administered in the United States were robustly effective in preventing infections in real-life conditions.

One is considered fully vaccinated two weeks after receiving the single dose of the Johnson & Johnson vaccine, or two weeks after receiving the second dose of the Pfizer-BioNTech or Moderna shots.

If you decide to travel, you might still have some questions. Here are the answers.

Will I still need to wear a mask and socially distance while traveling?

Yes. Under federal law, masks must be worn at airports in the United States, onboard domestic flights and in all transport hubs. The C.D.C. says that as long as coronavirus measures are taken in these scenarios, including mask wearing, fully vaccinated Americans can travel domestically without having to take a test or quarantine, although the agency warns that some states and territories may keep their local travel restrictions and recommendations in place.

For those wishing to travel internationally, a coronavirus test will not be required before departure from the United States unless mandated by the government of their destination. Vaccinated travelers are still required to get tested three days before travel by air into the United States, and are advised to take a test three to five days after their return, but will not need to self-quarantine.

Can I go abroad?

Yes, but only to countries that will have you.

More than half the world’s countries have reopened to tourists from the United States, including the countries of the European Union , which on June 18 added the United States to its “safe list” of countries, meaning that American travelers can now visit. While the European Union aims to take a coordinated approach to travel this summer, member states will be allowed to set their own requirements for travelers from individual countries based on their own epidemiological criteria, which means they may require testing or vaccination.

Some places like Turkey, Croatia and Montenegro had already been welcoming Americans with negative test results. Greece joined that growing list in May, ahead of most European countries, opening to fully vaccinated tourists and other foreigners with a negative test.

Many Caribbean nations have reopened to American tourists, but each has its own coronavirus protocols and entry requirements.

Here’s a full list of countries Americans can currently travel to.

What about domestic travel? Is it free and clear to cross state borders?

If you are fully vaccinated, the C.D.C. says you can travel freely within the United States and that you do not need to get tested, or self-quarantine, before or after traveling. But some states and local governments may choose to keep travel restrictions in place, including testing, quarantine and stay-at-home orders. Hawaii , for instance, still has travel restrictions in place.

Before you travel across state lines, check the current rules at your destination.

How are they going to check that I’m fully vaccinated?

Right now, the best way to prove that you have been vaccinated is to show your vaccine card .

Digital vaccine and health certificates showing that people have been vaccinated or tested are in various stages of development around the world and are expected, eventually, to be widely used to speed up travel.

The subject of “ vaccine passports ” is currently one of the most hotly debated topics within the travel industry, with questions over the equity of their use and concerns over health and data privacy.

In early April, Gov. Ron DeSantis of Florida issued an executive order that would ban local governments and state businesses from requiring proof of vaccination for services.

And in March, the European Union endorsed its own vaccine certificate , which some countries are already using, with more expected to adopt it by July 1.

But what about my kids? What’s the guidance on traveling with unvaccinated people?

The C.D.C. advises people against travel unless they have been vaccinated. If you must travel, the agency recommends testing one to three days before a trip and following all coronavirus guidance at your destination.

In May, the F.D.A. expanded its emergency use authorization of the Pfizer-BioNTech coronavirus vaccine to include adolescents between 12 and 15 years of age.

All air passengers aged two and older coming into the United States, including fully vaccinated people, are required to have a negative Covid-19 test result taken no more than three days before they board their flight.

What is my moral obligation to the places I visit where most people are not vaccinated?

The United States inoculation rollout has been among the fastest in the world, but there is a stark gap between its rapid rollout and the vaccination programs in different countries. Some nations have yet to report a single dose being administered.

Many countries are currently seeing a surge in new cases and are implementing strict coronavirus protocols, including mask mandates in public spaces, capacity limits at restaurants and tourist sites and other lockdown restrictions.

It is important to check coronavirus case rates, measures and medical infrastructure before traveling to your destination and not to let your guard down when you get there. Even though you are fully vaccinated, you may still be able to transmit the disease to local communities who have not yet been inoculated.

9 common questions about vaccines and travel

Joel Streed

Share this:

Travel does more than just transport you to a different place. It can broaden your perspective, increase your happiness, give you a chance to try new things, boost your creativity and help you recharge. Even planning a trip can be an exciting task. The anticipation of mapping an itinerary and scheduling your must-see attractions can bring a lot of joy and happiness.

One of the most important tasks before taking a trip is to make an appointment with a travel medicine specialist. These health care professionals help keep travelers safe and happy before and after their journeys.

Here are answers to common questions about travel medicine:

1. who should make an appointment with a travel medicine specialist.

Anyone planning a trip overseas can benefit from seeing a travel medicine specialist. However, a travel clinic appointment is critical if you are traveling to underdeveloped or developing countries where there's a higher risk of contracting severe communicable illnesses while abroad. It is also important for patients with certain medical conditions that make their immune systems weaker and more vulnerable to infectious diseases.

2. What vaccinations do I need to travel overseas?

All travelers should be vaccinated against the flu and current with COVID-19 vaccines and boosters.

In addition, it's important to complete the adult vaccination schedule that includes vaccinations for:

• Chickenpox (varicella)
• Diphtheria, tetanus and pertussis (DTP)
• Pneumococcal
• Measles, mumps and rubella (MMR)

Additional vaccines may be recommended depending on your travel itinerary. For example, hepatitis A vaccination is recommended if you are traveling to Southeast Asia. During your appointment, we can discuss which vaccines are appropriate for your itinerary.

3. Are there travel destinations that have different vaccination recommendations?

Yes. Infectious diseases thrive in different climates. If you travel to a new climate, you may be exposed to diseases to which you don't have any immunity.

Some infections are more prevalent in tropical settings compared to temperate climates. For example, typhoid and hepatitis A are more common in Southeast Asia because these communicable diseases can be spread through contaminated water. Some areas of Africa and South America have a higher prevalence of yellow fever and malaria, which are mosquito-borne infections.

The  Centers for Disease Control and Prevention (CDC)  has good information online for travelers for each travel destination.

Recommended vaccines may include:

• Hepatitis A
• Hepatitis B
• Japanese encephalitis
• Yellow fever

4. Can my primary care provider give me travel vaccinations?

It depends on your travel destinations and vaccine recommendations. I recommend starting the conversation with your primary care provider and reviewing the  CDC recommendations .

If you have a complex itinerary with multiple countries or are traveling to Southeast Asia or Africa, it's better to make an appointment at the travel clinic. I also would recommend patients with organ transplants and immunocompromising conditions seek travel medicine consultation to reduce the risk of illness during travel. During that appointment, we will review your itinerary, provide necessary vaccinations and discuss ways to prevent mosquito-borne or tick-borne diseases.

5. How long before my trip should I go to the travel clinic?

Plan to have an appointment at least four weeks before you travel. Some vaccines require several weeks for immunity to develop, while others require more than one dose of vaccine for full protection.

If your trip is to an underdeveloped or developing country, you may need to schedule an appointment up to two months in advance to receive a complete set of immunizations. This gives your body time to produce the protective antibodies, so you are well protected when you land at your destination.

6. Can I only go to the travel clinic before I travel?

No. The Travel and Tropical Medicine Clinic is available before or after travel. The team can provide consultative services and treatment if you get sick after you return home.

7. I'm going to an all-inclusive resort. Will I have a lower risk of getting sick?

Maybe, but no traveler should take safety for granted. Even in an all-inclusive resort, knowing how food is prepared or the water supply quality is not possible. Mosquitos and other insects could still be a concern. It's important to take all necessary precautions and follow vaccination recommendations when you travel, regardless of your accommodations.

8. How do I lower my risk of malaria when traveling?

Malaria is a disease caused by a parasite. It's spread to humans through the bites of infected mosquitoes. Prophylactic malaria medications are available and are started before the travel, continued during the stay and for a certain duration after returning home. A travel medicine specialist can review the risks and benefits of all prevention and treatment options.

9. How do I stay healthy while traveling?

Nothing can ruin a trip like illness. Make sure all your vaccinations and boosters are up to date, and get any new vaccinations recommended for your destinations.

Food and water safety is important while traveling. Only eat well-cooked food. Avoid eating from roadside stands and uncooked foods, like salad and raw vegetables. Drink bottled beverages only, including bottled water. This is especially important if you travel in resource-limited regions, such as Southeast Asia or Africa.

Hand hygiene is important at home and overseas. Wash your hands often using soap and hot water. Avoid crowded places, follow respiratory etiquette and consider optional masking. Mosquitos and bugs can transmit parasites and diseases, like yellow fever and malaria. Use mosquito repellents. Mosquito nets may be appropriate in some parts of the world, as well.

As you make travel plans, schedule an appointment with a travel medicine specialist to get the vaccinations and information you need to be healthy and safe on your journey.

Frequently Asked Questions: Guidance for Travelers to Enter the U.S.

Updated Date: April 21, 2022

Since January 22, 2022, DHS has required non-U.S. individuals seeking to enter the United States via land ports of entry and ferry terminals at the U.S.-Mexico and U.S.-Canada borders to be fully vaccinated for COVID-19 and provide proof of vaccination upon request.  On April 21, 2022, DHS announced that it would extend these requirements. In determining whether and when to rescind this order, DHS anticipates that it will take account of whether the vaccination requirement for non-U.S. air travelers remains in place.

These requirements apply to non-U.S. individuals who are traveling for essential or non-essential reasons. They do not apply to U.S. citizens, Lawful Permanent Residents, or U.S. nationals.

Effective November 8, 2021, new air travel requirements applied to many noncitizens who are visiting the United States temporarily. These travelers are also required to show proof of COVID-19 vaccination. All air travelers, including U.S. persons, must test negative for COVID-19 prior to departure. Limited exceptions apply. See  CDC guidance  for more details regarding air travel requirements.

Below is more information about what to know before you go, and answers to Frequently Asked Questions about cross-border travel.

Processing Changes Announced on January 22, 2022 

Q: new changes were recently announced. what changed on january 22.

A:  Since January 22, 2022, non-citizens who are not U.S. nationals or Lawful Permanent Residents have been required to be vaccinated against COVID-19 to enter the United States at land ports of entry and ferry terminals, whether for essential or nonessential purposes. Previously, DHS required that non-U.S. persons be vaccinated against COVID-19 to enter the United States for nonessential purposes.  Effective January 22, all non-U.S. individuals, to include essential travelers, must be prepared to attest to vaccination status and present proof of vaccination to a CBP officer upon request. DHS announced an extension of this policy on April 21, 2022.

Q: Who is affected by the changes announced on January 22?

A: This requirement does not apply to U.S. citizens, U.S. nationals, or U.S. Lawful Permanent Residents. It applies to other noncitizens, such as a citizen of Mexico, Canada, or any other country seeking to enter the United States through a land port of entry or ferry terminal.

Q: Do U.S. citizens need proof of vaccination to return to the United States via land port of entry or ferry terminals?

A: Vaccination requirements do not apply to U.S. Citizens, U.S. nationals or U.S. Lawful Permanent Residents. Travelers that exhibit signs or symptoms of illness will be referred to CDC for additional medical evaluation. 

Q: What is essential travel?

A:  Under the prior policy, there was an exception from temporary travel restrictions for “essential travel.” Essential travel included travel to attend educational institutions, travel to work in the United States, travel for emergency response and public health purposes, and travel for lawful cross-border trade (e.g., commercial truckers). Under current policy, there is no exception for essential travel.

Q: Will there be any exemptions? 

A: While most non-U.S. individuals seeking to enter the United States will need to be vaccinated, there is a narrow list of exemptions consistent with the Centers for Disease Control and Prevention (CDC) Order in the air travel context.

• Certain categories of individuals on diplomatic or official foreign government travel as specified in the CDC Order
• Children under 18 years of age;
• Certain participants in certain COVID-19 vaccine trials as specified in the CDC Order;   
• Individuals with medical contraindications to receiving a COVID-19 vaccine as specified in the CDC Order;
• Individuals issued a humanitarian or emergency exception by the Secretary of Homeland Security;
• Individuals with valid nonimmigrant visas (excluding B-1 [business] or B-2 [tourism] visas) who are citizens of a country with limited COVID-19 vaccine availability, as specified in the CDC Order
• Members of the U.S. Armed Forces or their spouses or children (under 18 years of age) as specified in the CDC Order; and
• Individuals whose entry would be in the U.S. national interest, as determined by the Secretary of Homeland Security.

Q: What documentation will be required to show vaccination status?

A:  Non-U.S. individuals are required to be prepared to attest to vaccination status and present proof of vaccination to a CBP officer upon request regardless of the purpose of travel.

The current documentation requirement remains the same and is available on the CDC website . Documentation requirements for entry at land ports of entry and ferry terminals mirror those for entry by air.

Q: What happens if someone doesn’t have proof of vaccine status?

A: If non-U.S. individuals cannot present proof of vaccination upon request, they will not be admitted into the United States and will either be subject to removal or be allowed to withdraw their application for entry.

Q: Will incoming travelers be required to present COVID-19 test results?

A: There is no COVID-19 testing requirement for travelers at land border ports of entry, including ferry terminals.

Q: What does this mean for those who can't be vaccinated, either due to age or other health considerations? 

A: See CDC guidance for additional information on this topic. Note that the vaccine requirement does not apply to children under 18 years of age.

Q: Does this requirement apply to amateur and professional athletes?

A: Yes, unless they qualify for one of the narrow CDC exemptions.

Q: Are commercial truckers required to be vaccinated?

A: Yes, unless they qualify for one of the narrow CDC exemptions. These requirements also apply to bus drivers as well as rail and ferry operators.

Q. Do you expect border wait times to increase?

A:  As travelers navigate these new travel requirements, wait times may increase. Travelers should account for the possibility of longer than normal wait times and lines at U.S. land border crossings when planning their trip and are kindly encouraged to exercise patience.

To help reduce wait times and long lines, travelers can take advantage of innovative technology, such as facial biometrics and the CBP OneTM mobile application, which serves as a single portal for individuals to access CBP mobile applications and services.

Q: How is Customs and Border Protection staffing the ports of entry? 

A: CBP’s current staffing levels at ports of entry throughout the United States are commensurate with pre-pandemic levels. CBP has continued to hire and train new employees throughout the pandemic. CBP expects some travelers to be non-compliant with the proof of vaccination requirements, which may at times lead to an increase in border wait times. Although trade and travel facilitation remain a priority, we cannot compromise national security, which is our primary mission. CBP Office of Field Operations will continue to dedicate its finite resources to the processing of arriving traffic with emphasis on trade facilitation to ensure economic recovery.

Q: What happens if a vaccinated individual is traveling with an unvaccinated individual?  

A:  The unvaccinated individual (if 18 or over) would not be eligible for admission.

Q: If I am traveling for an essential reason but am not vaccinated can I still enter?

A:  No, if you are a non-U.S. individual. The policy announced on January 22, 2022 applies to both essential and non-essential travel by non-U.S. individual travelers. Since January 22, DHS has required that all inbound non-U.S. individuals crossing U.S. land or ferry POEs – whether for essential or non-essential reasons – be fully vaccinated for COVID-19 and provide related proof of vaccination upon request.

Q: Are sea crew members on vessels required to have a COVID vaccine to disembark?

A:  Sea crew members traveling pursuant to a C-1 or D nonimmigrant visa are not excepted from COVID-19 vaccine requirements at the land border. This is a difference from the international air transportation context.

Entering the U.S. via Air Travel

Q: what are the covid vaccination requirements for air passengers to the united states  .

A:  According to CDC requirements [www.cdc.gov/coronavirus/2019-ncov/travelers/noncitizens-US-air-travel.html | Link no longer valid], most noncitizens who are visiting the United States temporarily must be fully vaccinated prior to boarding a flight to the United States. These travelers are required to show proof of vaccination. A list of covered individuals is available on the CDC website.  

Q: What are the COVID testing requirements for air passengers to the United States?  

A:  Effective Sunday, June 12 at 12:01 a.m. ET, CDC will no longer require pre-departure COVID-19 testing for U.S.-bound air travelers.

From vaccines to testing: What travelers need to know before the new US travel system on Nov. 8

• The U.S. is launching a new travel system on Nov. 8.
• Vaccinated foreign air travelers will need to show proof of full vaccination and test for COVID-19.
• The new travel system also adds more stringent testing requirements for unvaccinated U.S. travelers.

The United States is about to make it much easier for vaccinated international travelers to visit.  

The White House announced that a new air travel system will take effect Nov. 8, allowing entry for fully vaccinated foreign tourists .  The system is set to launch nearly two years after the U.S. began imposing travel restrictions to prevent the spread of COVID-19 . 

The move by the White House will essentially have the U.S. drop its travel ban on dozens of countries while also making entry more challenging for the unvaccinated. The new system will allow entry for foreign nationals only with vaccinations approved for emergency use by the World Health Organization and would add testing requirements for unvaccinated Americans.

Here’s what we know about the new travel requirements:

What are the entry requirements for foreign nationals?

Starting Nov. 8, non-citizen, non-immigrant air travelers   will need to show proof of full vaccination as well as a pre-departure negative coronavirus test taken within three days of travel before they can board a plane to the U.S.

Acceptable forms of proof of vaccination include:

• Digital or paper verifiable record, such as a vaccination certificate or a digital pass with a QR code.  
• Nonverifiable paper record, such as a printout of a COVID-19 vaccination record or COVID-19 vaccination certificate.
• Nonverifiable digital record, such as a digital photo of a vaccination card or record, downloaded vaccine record, downloaded vaccination certificate or a mobile phone application without a QR code.  

The U.S. will accept nucleic acid amplification tests, including PCR tests, and antigen tests. The rules will go into effect for passengers on planes leaving for the U.S. at or after 12:01 a.m. ET on Nov. 8.  

Airlines will collect basic personal contact information   from all U.S.-bound travelers for contact tracing. Airlines are required to keep the information on hand so the Centers for Disease Control and Prevention   can reach out to travelers who may have been infected or exposed to COVID-19.

Masking will be required, but there will be no quarantine mandate for vaccinated travelers or unvaccinated children .

► US  travel bans: How COVID-19 travel restrictions have impacted families and couples

The change will make entering the U.S. possible for travelers from countries now listed on the U.S. travel ban, which prohibits entry for travelers who have been in any of the regions within the past 14 days. The travel ban  took effect in early 2020 and includes :

• United Kingdom
• Republic of Ireland
• South Africa
• The European Schengen area (Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland, Monaco, San Marino and Vatican City)

Currently, the U.S. asks international air passengers only to get tested within three days of their flight to the U.S. and show either the negative test result or proof of recovery  from COVID-19 before boarding. 

What about the land borders with Mexico and Canada?

New travel rules will also take effect for foreign nationals arriving by land or passenger ferry.

Starting Nov. 8, fully vaccinated foreign nationals can cross the land borders for nonessential reasons such as tourism or visiting friends and family . These travelers will need to verbally attest to their reason for travel and vaccination status and be prepared to show proof of vaccination  upon request. U.S. Customs and Border Protection will accept both digital and paper records showing proof of vaccination, including documents not in English.   Foreign nationals will also need appropriate travel documentation to enter the country.  

CBP will spot-check travelers' vaccination documents, and those without documented proof of vaccination can be denied entry. Travelers under 18 will be exempt from the vaccination requirement as long as they are traveling with a fully vaccinated adult, according to Matthew Davies, CBP's executive director of admissibility and passenger programs.  

The new travel rules will go into effect as soon as a port of entry opens on Nov. 8, or at midnight for ports that operate 24 hours a day changes will go into effect at midnight on Nov. 8 for ports that operation 24 hours a day.  

U.S. citizens reentering the country should also bring a Western Hemisphere Travel Initiative document, such as a valid passport, trusted traveler program card, enhanced driver's license or enhanced tribal card. 

Entry rules along the border will change again in early January, with all travelers – including those traveling for essential purposes – required to show proof of full vaccination. 

► US land borders: Travelers in Mexico and Canada plan their next US visit after new land border policy announced

Which vaccines does the US accept for travel?

The CDC has announced that vaccines approved for emergency use by the U.S. Food and Drug Administration and World Health Organization will be accepted for air travel. White House officials expect the CDC to approve the same vaccines for travelers entering the U.S. by land or ferry.  

The FDA has authorized three COVID-19 vaccines for emergency use during the pandemic: Moderna, Johnson & Johnson and Pfizer-BioNTech, the last of which has received the FDA's full stamp of approval.

Vaccines with WHO approval for emergency use include:

• Johnson & Johnson
• Pfizer-BioNTech
• Oxford-AstraZeneca/Covishield 

The CDC confirmed that it would accept a mix-and-match approach to vaccinations. Travelers who have any combination of FDA- or WHO-approved vaccines will be considered fully vaccinated.

The new travel policy does not accept foreign travelers who have had COVID and received just one shot in a two-dose series. White House press secretary Jen Psaki said Tuesday that the administration will "continue to review" its entry requirements.  

► Covaxin gets WHO emergency approval: Travelers vaccinated with Covaxin can enter US   

► 'You feel lonely and left out': These fully vaccinated travelers want to visit the US. They may not be allowed in.

How do the new rules affect kids? 

Foreign nationals under 18 are exempt from the vaccination requirement. Children under two will not need to take a pre-departure COVID test.

Kids 2 and older traveling with a fully vaccinated adult can test three days prior to departure, while children traveling alone or with unvaccinated adults will need to get tested within one day of departure. 

Currently, all air passengers 2 or older, including U.S. citizens and permanent residents, need to show a negative coronavirus test to fly to the U.S.

What are the entry requirements for Americans?

The new travel system adds more stringent testing requirements for unvaccinated U.S. travelers.

Starting Nov. 8, unvaccinated U.S. citizens and permanent residents will need to take a test one day before departure and test again upon arrival in the U.S. 

► New travel rules: What US travelers need to know about the new COVID rules for international flights

Entry requirements will not change for vaccinated Americans. They will still need to show proof of a negative coronavirus test taken no more than three days before departure. 

Americans will not need to be fully vaccinated to board international flights to the U.S.

Are there any exemptions?

There is a limited set of travelers who are exempt from the vaccine requirement for entry.

Children under 18, certain COVID-19 vaccine clinical trial participants and travelers with adverse reactions to the vaccines – such as people who have had severe anaphylactic allergic reactions to a prior COVID-19 vaccine –  will be exempt.

People traveling on non-tourist visas from countries with less than 10% of its population vaccinated who need to enter the U.S. for emergency or humanitarian reasons are also exempt from the vaccine requirement. There are about 50 countries considered to have low vaccine availability at this time.

These exempt travelers will generally need to show that they will comply with public health mandates, including a requirement to be vaccinated in the U.S. if they plan to stay more than 60 days.  

Unless they have recovered from COVID-19 within the last 90 days, unvaccinated travelers  must agree to be tested with a COVID-19 viral test three to five days after their arrival and quarantine for seven days, even if their post-arrival test comes back negative. 

Unvaccinated travelers who are not U.S. citizens or permanent residents must also agree to self-isolate if their post-arrival test is positive or if they develop COVID-19 symptoms. 

Unvaccinated children under 18 will not need to quarantine but will still need to take a post-arrival test. 

► Who is exempt?: These select groups of unvaccinated foreign travelers can enter the US

The CDC will not give exemptions  to people who object to the vaccinations due to religious or moral convictions. 

There will also be testing accommodations for travelers who can prove they recently recovered from the coronavirus. These travelers will need to show a positive COVID-19 viral test result on a sample taken no more than 90 days before their flight's departure and a letter from a licensed healthcare provider or public health official saying they are cleared for travel.

The Administration will end the COVID-19 vaccine requirements for international air travelers at the end of the day on May 11, the same day that the COVID-19 public health emergency ends. This means starting May 12, noncitizen nonimmigrant air passengers will no longer need to show proof of being fully vaccinated with an accepted COVID-19 vaccine to board a flight to the United States. CDC’s Amended Order Implementing Presidential Proclamation on Safe Resumption of Global Travel During the COVID-19 Pandemic will no longer be in effect when the Presidential Proclamation Advancing the Safe Resumption of Global Travel During the COVID-19 Pandemic is revoked .

Vaccination

Pakistan is experiencing an outbreak of extensively drug-resistant typhoid fever. Travelers to Pakistan and other South Asian countries should take precautions.

• Get a typhoid fever vaccination
• Follow safe food and water guidelines

Vaccination can help prevent typhoid fever. CDC recommends vaccination for people traveling to places where typhoid fever is common, such as South Asia, especially India, Pakistan, or Bangladesh.

Visit a doctor or travel clinic to discuss options.

Two typhoid fever vaccines are available in the United States.

• Oral vaccine: Can be given to people at least 6 years old. It consists of four pills taken every other day and should be finished at least 1 week before travel.
• Injectable vaccine: Can be given to people at least 2 years old and should be given at least 2 weeks before travel.

Typhoid vaccines are not 100% effective. Always practice safe eating and drinking habits to help prevent infection.

Typhoid vaccines lose effectiveness over time. The injectable vaccine requires a booster every 2 years, and the oral vaccine requires a booster every 5 years. If you were vaccinated in the past, ask your doctor if it is time for a booster vaccination. Taking antibiotics will not prevent typhoid fever; they only help treat it.

Vaccine clinic on wheels: Rockland adds ways to get immunized amid national measles surge

Rockland County has added a mobile vaccination unit to its childhood vaccination efforts.

The new vaccination clinic on wheels comes as cases of measles are climbing worldwide, in the U.S. and in New York.

While Rockland has not seen a case of measles this year, the county managed a measles outbreak in 2018 and 2019. In 2022, Rockland County also saw the first case of polio in the U.S. in decades.

The van, purchased with federal COVID funds, is already up and running. The idea, county spokesperson Beth Cefalu has said, is to get the shots to where they're needed.

Plans for community visits could include sites in East Ramapo school district, county officials said. The greater Spring Valley area is home to a large new immigrant community and the district has reported many new enrollees from Haiti, Central and South America. Often, kids arrive without vaccination records from their home country. Providing on-site shots could help kids catch up and ensure they meet state vaccination regulations for school attendance.

Vaccination rates have slipped in recent years, for various reasons, all over.

Rockland County, though, has long had its own challenges with pockets of low childhood vaccination rates.

Urgency amid Rockland's vulnerability

As of April 18, the U.S. Centers for Disease Control and Prevention had documented 125 measles cases across the U.S. in 2024. That includes three cases in New York; two in NYC and one in Nassau County, according to the New York State Department of Health.

Rockland County remains vulnerable, county officials have said.

In 2018-2019, Rockland witnessed a measles outbreak that ultimately sickened 312; there were 649 cases found in New York City.

“To successfully prevent measles from resurfacing in this county we need cooperation from all communities,” County Executive Ed Day said in a statement.

Polio: Rockland hits full year with no virus found in wastewater

In July 2022, a Monsey man suffered permanent paralysis from polio, an outcome often feared before a vaccine came into use in the early 1960s. The man had not traveled outside the U.S.

Wastewater testing showed the polio virus had been present for months. Subsequent testing of sewage treatment systems around downstate New York have not shown the virus' presence since February 2023.

Focus on upping immunization numbers

County officials have been focused on upping immunization rates since the measles outbreak in the last teens, throughout COVID and through the recent polio scare.

The county's health department recently launched a childhood immunization campaign .

Cefalu said that Rockland Health Department clinics have seen an increase in visits by 50% between 2021 and 2023.

Still, as of Aug. 1, 2023, New York state health records showed pockets of low polio vaccination rates among Rockland County children age 2 and under. For example, in the 10952 ZIP code, which covers the greater Monsey area, just 41.4% of babies and toddlers were vaccinated against polio; in the 10977 postal code, the Spring Valley area, the polio vaccination rate was 55.9%.

How to get vaccinated

Rockland County clinics provide free vaccines through the Vaccines for Children and Vaccines for Adults programs. Find out about eligibility at 845-364-2520/2524. 

Clinic appointments are available by appointment (call 845-364-2520 to schedule) at the following times and locations:
