Ideally, set one up 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 travelin
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.
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.
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.
See the CDC’s destinations page and look up the country or countries you will visit.
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.
