Re: Hepatitis B Vaccine
The Hepatitis B vaccine is given in three doses - Initial dose, second dose at least one month after the first dose, third dose six months after the first dose. If you are late on the second dose, just resume where you left off and get the third dose four months later. You do not need to re-start the series if you are late. It's also prudent to get a titer three months after your third dose to make sure the vaccination took.
