Recent outbreaks — from Ebola in parts of Africa to illnesses on cruise ships — make headlines, but many infectious threats are closer to home. Some vaccines are location-specific (like yellow fever or rabies for certain activities), while others, such as measles, are a global concern. The CDC advises that all international travelers be fully vaccinated against measles with the MMR vaccine because cases are rising worldwide.
Before your next flight, take a few steps to confirm which vaccinations and precautions will keep you healthy during and after travel.
Check your routine immunizations
Start by reviewing your regular vaccines. Many provide long-lasting protection, but boosters are sometimes needed for travel. Childhood shots for tetanus or polio may require updates before visiting higher-risk areas. Also consider seasonal shots like flu and COVID vaccines: they won’t cover every strain but can reduce the chance of getting sick on a plane or in crowded settings.
Use official travel-health resources
Visit the CDC Travelers’ Health website for destination-specific vaccine and medication recommendations, packing lists, and safety tips. The World Health Organization also publishes international travel and health advice. These sites are a good first step to see what diseases are a concern where you’re going.
Get a travel health consultation
A travel clinic visit tailors recommendations to your itinerary, health history, and planned activities. Despite this, many travelers skip consultations for a variety of reasons. Common misconceptions include:
– “I won’t get sick.” You can’t predict exposures — think of a consultation like wearing a seat belt: a simple precaution against unknown risks.
– “My primary care doctor is enough.” Primary doctors are valuable but may not always have the most current travel-specific guidance. Travel clinics track outbreaks and traveler needs more closely.
– “I read everything online.” Official sites are essential, but an in-person consult personalizes advice (a backpacker’s needs differ from a short business trip).
– “Vaccines make you sick.” Serious reactions are rare. Vaccination prompts antibody production rather than causing the disease itself.
– “It’s too expensive.” Some vaccines (rabies series, for example) can be costly, but most consultations run roughly $50–$150 and many vaccines are under $100. You’re not obligated to get vaccines during the visit — you’ll only receive recommendations.
Scheduling and clinics
Book a travel consultation at least a month before departure when possible, because many vaccines take 10–14 days to become effective and some require multiple doses. That said, a last-minute visit is better than none — clinics can still offer protection even on the day you fly. Travel clinics are widely available in most cities; some networks have hundreds of locations.
During the appointment you’ll review destinations, activities, medical history, and needed prescriptions (e.g., malaria prophylaxis, antibiotics for traveler’s diarrhea). If a multi-dose vaccine is advised, plan follow-up visits as required. Check whether your insurance covers preventive travel care — some plans do, but others (including Medicare) may not. Health savings accounts often allow these expenses.
Understand how vaccines work for travel
Not all vaccines provide the same duration or type of protection. For instance, oral typhoid vaccine can protect for about five years, whereas the injectable option may last two. Rabies pre-exposure vaccination doesn’t eliminate the need for medical care after an animal bite; it gives you extra time to seek prompt treatment and reduces but does not remove risk.
Ask your travel provider about side effects, contra-indications, and timing. The CDC’s Vaccine Information Statements (VIS) explain each vaccine, who should get it, and potential side effects — look up a VIS by searching the vaccine name plus “VIS.”
Prevention beyond vaccines
Vaccination prevents many serious conditions, but the most common traveler complaint is diarrhea, which is often avoidable with basic food and water precautions. Follow local hygiene guidance: avoid risky foods, be cautious with tap water where advised, and heed warnings about swimming in freshwater in certain regions. For other infections, prescriptions like malaria pills can significantly lower your risk if you’re visiting endemic areas. For diseases with active outbreaks (such as certain Ebola outbreaks), the best protection is avoiding travel to affected areas.
Bottom line
Take disease risks seriously but don’t let them stop you from traveling. Use official resources, get a targeted travel health consultation, and update vaccines as recommended so you can travel with greater safety and peace of mind.
