Answer

I assume that you are talking about hepatitis B vaccine. If you are taking your vaccine now, there is no need to take it again, unless you have an ongoing risk of getting infected, such as having sex with a person with chronic HBV infection. In these cases, we do periodically check your HB surface antibodies to see if you need a "booster" (eg, one shot) to boost your immune responses.
