for hepatitis A two doses{six months apart} after the age of one year are given.after that natural immunity is built for longer time. hence no booster is required. even if the booster is given it wouldn't be of any use.

Data have shown that after a full primary immunization course protective antibodies persist for more than 10 years in healthy individuals and underlying immune memory provides protection far beyond the duration of anti HAV Antibodies. So it can be concluded that there is no evidence to lend support to HAV booster vaccination after a full primary vaccination course in healthy individuals. However for special patient groups further research is needed.
