Hi Taylor

Fortunately, you do not need to provide any proof of vaccination certificate before you are allowed to enter the country. However, we strongly suggest that you ask for your doctor advice for vaccination before traveling to Vietnam where the weather condition is pretty much different from USA.

You can also take a look on this page for some Useful advice: http://www.vietnamonline.com/planning/vaccination.html

We wish you an enjoyable trip to Vietnam.
