What if Im behind on my Hepatitis B vaccines?
When the hepatitis B vaccine schedule is interrupted, the vaccine series does not need to be restarted. If the series is interrupted after the first dose, the second dose should be given as soon as possible and the second and third doses should be separated by an interval of at least 8 weeks. It is not necessary to restart the vaccine series for infants switched from one vaccine brand to another, including combination vaccines.
