Two things...the vaccine for Hep B and A does work against later contracting them. If you have any one of A,B, or C you do not need to complicate matters by getting any of the others. The only Hep that doesn't have a vaccine is C. That's what we all have it, I guess! But A is food borne so it would be especially important wherever we live. The pills and Peg-I come seperately but you order them at the same time. Are you feeling okay about the course you are headed toward at this point?
