Before You Fly: Vaccines, Consults, and Hidden Risks

Recent outbreaks like Ebola in Africa and hantavirus aboard a cruise ship have made headlines in a hurry. But for many travelers, the bigger threat is the kind you don’t notice until it’s too late — a risk you can’t “feel” at the airport.

The guidance coming out of the U.S. is blunt. The Centers for Disease Control says, “measles cases are rising in many countries around the world,” and adds that all international travelers should be fully vaccinated against measles with the measles-mumps-rubella (MMR) vaccine.

That’s where planning starts: not with panic, but with the right medical check before boarding. Some vaccines mainly apply to certain regions or specific activities. Others are relevant almost everywhere — and even if you think you’re already covered. the risk can shift depending on where you’re going.

Keeping up with immunizations is often the simplest first move. Many common vaccines protect people for a decade or more, but that’s not guaranteed everywhere. If you were vaccinated against tetanus and polio as a child. a doctor may still recommend a booster before you travel to an area with higher risk.

Seasonal illnesses deserve the same attention, too — especially because you may be more likely to catch them while flying than once you land. Don’t overlook Covid and the flu. Vaccines won’t protect against all strains, but they can reduce the chance you bring home a vacation-ruining bug.

For international travelers, the first stop is clear. Corey McVey. director of nursing at Passport Health in Chicago and Wisconsin. says the CDC’s dedicated Travelers’ Health site should be where people begin. From the homepage. travelers can select their destination country and get a breakdown of recommended vaccines and medications for different types of travelers. along with other health and safety tips and medical packing lists. If you want a second reference point, the World Health Organization (WHO) website also offers international travel and health information.

It’s not just about what to check — it’s about who actually does it. McVey says, “Only 10% of travelers that should seek travel consultation do.” That gap helps explain why so many people end up scrambling.

Part of the problem is the belief that getting sick is a non-issue. McVey calls it the most common reason people skip consultations: “People think they’ll be fine. They won’t come across illness or diseases. But you should get a consultation for the same reason you wear a seat belt. You don’t know about others. You don’t know about the people cooking your food.”.

Another misconception is thinking a primary care visit replaces travel medicine. McVey says travelers should consult their physician first. and that primary care doctors often recommend a travel clinic — especially when vaccinations are needed that they don’t carry. But he also warns that primary care physicians don’t always have the most current information. especially if an outbreak has changed the picture. “Travel clinics are most in tune with international travelers’ needs.”.

Some people rely on online information alone. but McVey says the CDC website should be a starting point. not the finish line. A travel consultation can tailor recommendations to each traveler based on health history risks and the specific activities planned. “The needs of a backpacker traveling through Thailand are different than a business traveler who will only be in Bangkok a few days.”.

There’s also a misunderstanding about what vaccines do. McVey says some people think the shot gives them the disease and that they’ll get sick and then be immune. “Very few people get sick from the vaccines. It’s an antibody buildup.”

And then there’s cost. While some vaccinations can be expensive — rabies can cost over $1,000 for the series — McVey says that’s an extreme example. Travel consultations typically cost $50 to $150, and most vaccines cost less than $100. He also stresses that the visit is a consultation only: “you are under no obligation to get them.”.

Finding a clinic is often easier than people assume. Travel clinics are common in most cities, and Passport Health alone has over 300 locations in North America.

Timing matters, because even good plans fall apart if they arrive too late. McVey advises scheduling at least a month before departure. since vaccines take 10 to 14 days to reach full effectiveness and some need to be administered as a series. Still. he adds a clear message for procrastinators: “We’ll vaccinate even if they are getting on an airplane that day. It’s never too late.”.

During the consultation. the plan is built around real details: which regions you’ll visit. what activities you’ll be doing. and what health risks you should expect. The doctor may recommend vaccines as well as prescriptions like malaria pills and antibiotics to treat traveler’s diarrhea. If a multi-dose vaccine is needed, follow-up visits in a week or two may be required.

Insurance coverage can vary. McVey notes that some insurance plans cover preventative health for international travel, but some including Medicare do not. If you have a health savings account, this is an eligible expense.

Understanding the vaccines themselves is just as important as getting them. Not all immunizations work the same way or for the same length of time. For example, there is an oral typhoid vaccine that protects for five years, while the injectable version lasts two years.

Even with rabies, the name can mislead. The rabies vaccine does not fully protect someone from rabies. Even after a three-dose vaccine — the most extensive option — a person who is bitten or scratched by an animal that may be infected still needs medical attention. The vaccine buys time to seek treatment. so someone may wait until returning home instead of rushing to a hospital in a foreign country. but the need for care remains.

A travel doctor can walk people through these details. along with potential side effects. and use the CDC’s Vaccine Information Statements (VIS) to explain which diseases pose risks. who should or shouldn’t get the vaccine due to age or health concerns. and what side effects to watch for. People can search for a specific VIS by typing the disease name followed by “vis” into a search engine.

Vaccinations help prevent many serious illnesses, but they don’t cover everything. McVey says the number one health risk for travelers is diarrhea, and it can be prevented in multiple ways. That includes avoiding tap water in some areas and following best practices around hygiene and sanitation.

Food and water choices are part of it, too. A travel doctor will advise what kinds of foods to avoid to protect against food- and water-borne illness and what activities to steer clear of — including swimming in freshwater lakes in areas that carry dangerous bacteria.

Some risks can also be reduced through prescription. McVey points to malaria medication while traveling through at-risk areas as a way to greatly reduce the odds of contracting the disease.

Yet some illnesses remain stubborn. The Ebola strain currently affecting DRC and Uganda is still not fully preventable. McVey’s bottom-line defense against such diseases is avoiding places where they’re found.

Taken together, the message isn’t to fear travel. The risk of disease abroad should be taken seriously, but it shouldn’t automatically become a reason to stay home. A travel consultation can prepare you with vaccinations and medications — and. just as importantly. with education — so you can travel to far corners of the globe with more peace of mind.
