There has been evidence of chikungunya virus transmission in Vietnam within the last 5 years. Chikungunya vaccination may be considered for the following travelers:

• People aged 65 years or older, especially those with underlying medical conditions, who may spend at least 2 weeks (cumulative time) in indoor or outdoor areas where mosquitoes are present in Vietnam, OR
• People planning to stay in Vietnam for a cumulative period of 6 months or more

Recommended for unvaccinated travelers one year old or older going to Vietnam.

Infants 6 to 11 months old should also be vaccinated against Hepatitis A. The dose does not count toward the routine 2-dose series.

Travelers allergic to a vaccine component should receive a single dose of immune globulin, which provides effective protection for up to 2 months depending on dosage given.

Unvaccinated travelers who are over 40 years old, are immunocompromised, or have chronic medical conditions planning to depart to a risk area in less than 2 weeks should get the initial dose of vaccine and at the same appointment receive immune globulin.

Recommended for unvaccinated travelers of all ages traveling to Vietnam.

Recommended for travelers who

• Are moving to an area with Japanese encephalitis to live
• Spend long periods of time, such as a month or more, in areas with Japanese encephalitis
• Frequently travel to areas with Japanese encephalitis

Consider vaccination for travelers

• Spending less than a month in areas with Japanese encephalitis but will be doing activities that increase risk of infection, such as visiting rural areas, hiking or camping, or staying in places without air conditioning, screens, or bed nets
• Going to areas with Japanese encephalitis who are uncertain of their activities or how long they will be there

Not recommended for travelers planning short-term travel to urban areas or travel to areas with no clear Japanese encephalitis season. 

CDC recommends that travelers going to certain areas of Vietnam take prescription medicine to prevent malaria. Depending on the medicine you take, you will need to start taking this medicine multiple days before your trip, as well as during and after your trip. Talk to your doctor about which malaria medication you should take.

Cases of measles are on the rise worldwide. Travelers are at risk of measles if they have not been fully vaccinated at least two weeks prior to departure, or have not had measles in the past, and travel internationally to areas where measles is spreading.

All international travelers should be fully vaccinated against measles with the measles-mumps-rubella (MMR) vaccine, including an early dose for infants 6–11 months, according to CDC’s measles vaccination recommendations for international travel.

Dogs infected with rabies are sometimes found in Vietnam.

If rabies exposures occur while in Vietnam, rabies vaccines are typically available throughout most of the country.

Rabies pre-exposure vaccination considerations include whether travelers 1) will be performing occupational or recreational activities that increase risk for exposure to potentially rabid animals and 2) might have difficulty getting prompt access to safe post-exposure prophylaxis.

Please consult with a healthcare provider to determine whether you should receive pre-exposure vaccination before travel.

For more information, see country rabies status assessments.

Recommended for most travelers, especially those staying with friends or relatives or visiting smaller cities or rural areas.
