Travel vaccine guides

Before a trip abroad, the CDC’s Travelers’ Health pages list which vaccines are required, recommended, or worth a conversation for each destination. These guides translate those pages for families: how far ahead to book a travel clinic, why hepatitis A is often already covered by the childhood schedule, when yellow fever proof is demanded at a border, what the International Certificate of Vaccination (the yellow card) actually documents, and what changes when a child is too young for a given vaccine. Each guide links to the CDC or WHO page it is based on and shows a Published date and, once revised, an Updated date. Confirm the final list with a physician or a travel clinic before you leave.

One question from each guide above, answered here. Follow a question to the guide that works through it in full.

Where do you check Costa Rica's official recommendations?

On CDC's Travelers' Health destination page for Costa Rica, reached from the destinations list at wwwnc.cdc.gov. That page is the primary source: it carries the travel health notices, the vaccine and medicine table with the condition attached to each entry, and the malaria transmission areas by province. It changes without announcement, so read it again close to departure rather than trusting a screenshot taken months earlier.

Do I need to open a page for a country I only transit?

Open it if you will leave the airport, and open it anyway if the country could affect an entry requirement elsewhere. Some yellow fever rules depend on countries visited before arrival, including short stops, so a transit that looks irrelevant can change what a later border asks for. Recommendations do not average themselves: two countries means two pages.

At what age can a child receive JE vaccine?

CDC's Japanese encephalitis hub states that a JE vaccine is approved for use in U.S. travelers aged 2 months and older, and the Yellow Book notes that the inactivated vaccine IXIARO was licensed by the FDA in 2009 for travelers aged 2 months and up. Whether a particular infant should receive it is an itinerary conversation with a clinician, not an age rule on its own.

Is rabies pre-exposure vaccine needed for Western Europe or Japan?

Usually not, and CDC does not treat it as a routine vaccine for any destination. The global rabies burden that CDC describes falls overwhelmingly on countries where dogs roam freely and post-exposure care is hard to reach quickly. Check the specific destination page for the countries on your itinerary rather than assuming a region is uniform, and raise any animal-contact plans with a clinician.

Can a pharmacy give travel vaccines?

Some pharmacies give some of them, and what they may give is set by state law and by what the pharmacy stocks. Hepatitis A and typhoid are more commonly available than rabies pre-exposure or Japanese encephalitis. Yellow fever is different: the CDC states that travelers need an authorized yellow fever vaccine center for that dose and its certificate. Call and ask before you go.

Is a state immunization registry printout accepted at a border?

Not as proof of vaccination for travel where an International Certificate of Vaccination or Prophylaxis is required. The requirement points to the model certificate in Annex 6 of the International Health Regulations, signed by the supervising clinician and stamped by an authorized center. A registry printout is a strong document for schools, camps and new clinicians, and worth carrying abroad for medical care, but it is not the certificate an entry rule names.

Does one parent's yellow card cover a child?

No. Annex 6 of the International Health Regulations is unambiguous: "Certificates are individual and shall in no circumstances be used collectively. Separate certificates shall be issued for children." Each vaccinated traveler needs their own booklet in their own name. For a child too young to write, the same annex says a parent or guardian signs the certificate on their behalf.

Do cruise lines set their own vaccine rules?

Yes, and they are separate from anything CDC publishes. A cruise line's health policy is a company rule that can change between bookings and can differ from the requirements of the countries on the itinerary. CDC's cruise page even directs sick travelers to ask their line about rescheduling. Read the line's own pre-boarding documents for its rules, and read the CDC destination pages for the countries' rules.

Is Japanese encephalitis vaccine needed for a two-week city trip?

Usually not, but the country page decides. CDC's Japan and Thailand pages, checked on September 3, 2026, recommend the vaccine for people moving to an affected area or staying about a month or more, and suggest considering it for shorter trips that involve rural areas, hiking, camping, or other outdoor exposure during transmission season. A two-week itinerary spent in cities generally falls outside that description, but the judgment belongs to a clinician who has seen the nights.

Is a yellow fever certificate required for every African country?

No. Requirements are set per country and are printed on each CDC destination page, separately from CDC's own health recommendation. The Kenya page, checked on September 3, 2026, listed the vaccine as not required for direct travel from the United States but required for travelers 1 year and older arriving from a country with transmission risk. Other countries word their rules differently, so read each page on the route.

Is yellow fever vaccine needed for Europe?

Generally no for direct travel from the United States. CDC's France page listed yellow fever vaccine as both "not recommended" and "not required" when checked on September 3, 2026, and other European pages read similarly. Entry lines are per country and can change, and some depend on arriving from a country with yellow fever transmission risk, so open the destination page for each country on your ticket rather than trusting a regional summary.

Is yellow fever vaccine required to enter Mexico?

No. CDC's Mexico traveler page listed yellow fever vaccine as "not recommended" and "not required" when checked on September 3, 2026. Entry requirements are set by countries and can change, and some rules depend on where a traveler has been rather than where they are landing, so confirm the live line on the CDC Mexico page close to your departure date rather than relying on a saved screenshot.
