Hepatitis A Booster. This booster is administered 6 to 12 months after you have received an initial dose of the hepatitis A vaccine. You should get the booster if you continue to travel in high-risk areas with poor sanitation.
Hepatitis B vaccine is a series of 3 shots. Once you have received all 3 doses you are covered and do not need any additional doses. Hepatitis B vaccine consists of three shots - but also you need to then get a blood test. The blood test will show whether you have adequate immunity or not. If you do - immunity is for life and you won't need any more shots. If you don't you will need a further booster shot and repeat blood test.
