Do you only need to get hepatitis a & b vaccines once in your life?

Hep vax: You need to get one series of three Hepatitis B immunizations in your life and one series of two Hepatitis A immunizations spaced correctly apart. If a blood test showed no immunity that would be only time they would need to be repeated.

Vaccines hep A & B: Yes, they are both given as a series. Hep B is a three shot series; the first two are 1-2 months apart and the third is 6 months after the first. Hep A is a 2 shot series two months apart and you should be good. No boosters are required.
