No immunizations are currently required for visiting Vietnam. A yellow fever vaccination is required if you are arriving from another country with risk of yellow fever. This vaccination, which is valid for 10 years, must be administered at least 10 days before your arrival in the destination with yellow fever risk. Travelers must bring along their International Certificate of Vaccination or Prophylaxis (ICVP) as proof of vaccination. Hepatitis A and Typhoid are recommended. Hepatitis B, Japanese Encephalitis, Malaria, and Rabies preventatives are also loosely recommended depending on where you plan to travel in Vietnam. For the most current information, please consult your doctor and/or check out the Center for Disease Control web-site.
