Vaccinations in Vietnam are recommended and are very similar to the other countries in Southeast Asia. If you’re only visiting Vietnam for a week or two, you have enough with two vaccinations. If you stay in Vietnam or Thailand or Indonesia for example, you need more than two vaccinations. A vaccination is recommended against MMR, but most likely you got this as a child.
If you’ve been in some parts of Africa and / or South America, you have a chance of yellow fever. If you’ve been seven days before your visit to Vietnam in a yellow fever region, you are required to have a vaccination against it.
Whatever the length of your trip is these two vaccines are always recommended:
If you stay more than two weeks in Vietnam or combined with other countries in Southeast Asia, then it is highly recommended to get a vaccination against typhoid fever. Will you stay away for several months? Then you’d better take vaccinations against hepatitis B and rabies.
Always check your own doctor or a traveler’s vaccination center for professional counseling. Be sure to tell him what your plans are. If you are planning to do a lot of outdoor and other activities, including camping, hiking, biking, adventure travel, and caving, that put you at risk for animal bites, which can cause rabies.
