Breaking: Travelers urged to update vaccines now as measles surges, new options arrive
I can confirm a sharp rise in travel-linked measles cases across the United States, with a fast-moving outbreak in South Carolina. Health departments have reported 111 confirmed cases there, most in people without shots, and more than 250 people in quarantine. Nationwide, 1,912 measles cases have been logged this year across 43 states. That is a wake-up call before holiday and winter trips. [IMAGE_1]
Why this matters for your next trip
Measles spreads through the air and lingers in rooms for up to two hours. One sick person can infect many others. Airports, buses, and family gatherings make spread more likely. If your MMR is not up to date, you are at risk.
The U.S. could face a setback on measles control if travel keeps feeding outbreaks. This is preventable. Two doses of MMR protect well. If you plan to travel, check your status now. Do not wait until the week before you fly.
Measles is contagious before the rash appears, and up to four days after. If you think you were exposed, call your doctor before visiting a clinic to avoid exposing others.
What to get before you go
Start with routine vaccines. That means MMR, tetanus and whooping cough, flu, and a current COVID-19 shot. Ask about RSV if you are 60 or older, or if you are pregnant during RSV season. These shots lower your chance of severe disease and lower spread to family and fellow travelers.
For many destinations, you may also need travel-specific protection. Common ones include:
- Hepatitis A and typhoid for food and water safety
- Yellow fever for parts of Africa and South America, required for some borders
- Polio booster for some regions with ongoing spread
- Rabies pre-exposure for high-risk activities or remote travel
- Japanese encephalitis for long stays in rural parts of Asia
New chikungunya protection arrives
I am also tracking the rollout of new shots that target chikungunya. This painful mosquito-borne illness has caused major outbreaks in the Caribbean, Central and South America, Africa, and Asia. The new options expand protection for travelers who will be outdoors, visit friends and relatives, or stay for weeks.
One vaccine, Ixchiq, is live and has age-related limits because of safety concerns in older adults. Another, Vimkunya, uses a non-replicating design and is being introduced more widely. Ask your clinician which option fits your age, health, and itinerary. If your trip includes areas with chikungunya, this belongs in your plan. [IMAGE_2]
Book a travel health visit six to eight weeks before departure. Some vaccines need more than one dose, and live vaccines need at least two weeks to work.
What the safety reviews mean
Federal agencies are reviewing safety data on several vaccines, including RSV and COVID-19. Reviews like these are common in medicine. They test systems that watch for rare side effects. Current guidance remains in place while reviews continue. The big picture is stable, vaccines used in routine care and travel have strong safety records. If you have questions, bring them to your visit. Your personal risk, health conditions, and destination matter.
How to prepare, step by step
- Book a telehealth or in-person travel consult now. Bring your itinerary and medical history.
- Gather records. A digital copy on your phone helps at borders and clinics.
- Update routine shots, then add destination vaccines. Space live vaccines by at least two weeks if needed.
- Ask about malaria prevention, safe water tips, and insect bite control. There is no malaria vaccine for most travelers, but pills work well.
- Pack proof of vaccination and a list of medicines. Include your insurer’s travel number.
Some countries require proof of yellow fever vaccination for entry. Airlines can check this before you board. Do not leave it to chance at the gate.
Frequently Asked Questions
Q: I had MMR as a child. Do I need another dose before travel?
A: Most people with two documented doses do not need another. If you lack records or were born in 1957 or later, your clinician may test immunity or give MMR.
Q: How soon before my trip should I get shots?
A: Aim for six to eight weeks before departure. If you are leaving sooner, go anyway. Even one timely dose can help.
Q: Can my 6 to 11 month old get MMR for travel?
A: Yes, infants in that age range can get an early travel dose. They will still need the routine two-dose series later.
Q: Are travel vaccines covered by insurance?
A: Coverage varies. Many plans cover routine shots. Some travel vaccines are out of pocket. Ask your insurer and the clinic before you book.
The bottom line
Travel can be safe and joyful, even during outbreaks, if you prepare. Update your MMR, review routine shots, and add destination vaccines like hepatitis A, typhoid, yellow fever, and chikungunya where needed. Use telehealth to plan early, keep digital records, and time doses so protection is in place when you board. Your trip depends on your health, and your health depends on what you do now.
