A member asked:
My husband was accidentally given a hepb vaccine instead of a tetanus shot at his physical. will this offer any protection against hepb, or no?

Not with one dose: Hepatitis b vaccine would not offer significant immunity with dose. Most people get a series of 3 doses to develop lasting immunity.

Needs at least two: Your husband will need at least two hepatitis b shots to have some protection against hepatitis b. Full protection comes with full three shot series.
