You should be vaccinated against Hep A. That is a newer vaccine that is being pushed really for everyone (travel or no travel). It is a two dose vaccine, you receive one now and one 6 months to two years later, that you should start at least six weeks before you travel. I know it is later than that…but something is better than nothing.
If you are not vaccinated against Hep B (you should be if you were in college or high school…but double check) start that series. It should be a three dose series.

Most adult doctors will not have Hep A (you can call…but you mostly find that available in pediatric practices), but you should be able to update your TDaP and start Hep B there. For Hep A if your doctor does not offer it you can go to the Health Dept in your county to receive that (you could also get TDaP and Hep B there if you only wanted to make one trip!) and they will administer it at a discounted price…they will not file your insurance!
