International Travel - What you need to know about vaccinations and travel
Have you scheduled a visit to your doctor or a travel medicine provider?

Ideally, set up a doctorís visit 4 to 6 weeks before your trip. Most vaccines take time to become effective in your body and some vaccines must be given in a series over a period of days or sometimes weeks. If it is less than 4 weeks before you leave, you should still see your doctor. You might still benefit from shots or medications and other information about how to protect yourself from illness and injury while traveling.

Are you aware of which types of vaccinations you or those traveling with you may need?

The Centers for Disease Control and Prevention (CDC) divides vaccines for travel into three categories: routine, recommended, and required. While your doctor will tell you which ones you should have, it's best to be aware of them ahead of time.

Routine Vaccinations

Be sure that you and your family are up to date on your routine vaccinations. These vaccines are necessary for protection from diseases that are still common in many parts of the world even though they rarely occur in the United States. If you are not sure which vaccinations are routine, look at the schedules below.
The U.S. routinely schedule for childhood immunizations. This schedule may need to be adjusted if a child is traveling. See the section on this below.

Recommended Vaccinations

These vaccines are recommended to protect travelers from illnesses present in other parts of the world and to prevent the importation of infectious diseases across international borders. Which vaccinations you need depends on a number of factors including your destination, whether you will be spending time in rural areas, the season of the year you are traveling, your age, health status, and previous immunizations.

Search by country at the top of this page to find out which vaccinations are recommended, or see our destinations page and look up the world region you will visit.

Required Vaccinations

The only vaccine required by International Health Regulations is yellow fever vaccination for travel to certain countries in sub-Saharan Africa and tropical South America. Meningococcal vaccination is required by the government of Saudi Arabia for annual travel during the Hajj.
