Vaccines are one of the most effective ways to protect yourself against infectious diseases when you’re traveling internationally. Some diseases are more common in other parts of the world, so it’s important to be updated with your immunization schedule and complete your booster doses if you have missed taking them.
There are three types of vaccines you need in order to travel:
1. Routine vaccines
- Hepatitis A
- Hepatitis B
- Haemophilus influenzae type B
- Human papillomavirus
2. Recommended vaccines
Recommended vaccinations include the list of all the vaccines that protect international travelers from diseases that occur commonly in other parts of the world. Not all vaccines are recommended for everyone, however. Your doctor will determine which vaccines you need after considering a few factors including:
- Your destination
- Whether you will be spending time in rural areas
- Season of the year you are traveling
- Your age and overall health
- Your immunization history
- Rabies vaccine: Rabies spreads from dogs to humans. You may need a vaccine for it if you travel to parts of Thailand, Vietnam, Brazil, China, the Philippines, Sri Lanka, and Indonesia.
- Vaccine for typhoid fever: This disease spreads through contaminated water and food. It is more common in South Asia, especially India, Pakistan, and Bangladesh.
- Vaccine for Japanese encephalitis: This condition spreads via mosquito bites. You may need a shot of this vaccine if you are traveling to Asian countries or western Pacific regions.
3. Required (or mandatory) vaccines
Before entering some countries, you will need to provide your vaccination status for certain illnesses. For example:
When should I get vaccinated before traveling?
If you are planning to travel, you should visit your health care provider at least 4-6 weeks before your trip. This is because many vaccines need to be completed in several rounds, each separated by a specified interval of several days or weeks. Visiting several weeks before the trip ensures that you complete all doses and develop enough immunity.
Keep in mind that your doctor may not stock travel vaccines, so you may need to wait until they order one for you. You can visit a travel clinic instead. To find one near you, go to the travel clinic locator on the Traveler's Health section of the Centers for Disease Control and Prevention (CDC) website.
If you have a pre-existing medical condition or are visiting many countries in one trip, it is recommended to consult a travel medicine specialist.
Can I get travel vaccines in a country outside the U.S.?
The CDC does not recommend that you get vaccinated in another country you travel to because of the following reasons:
- Most vaccines need to be administered well before entering another country to provide you with full protection against diseases.
- Vaccines available in other countries may be less effective or different from the ones used in the U.S.
