I have completed a 4-dose series of hepatitis vaccine when i was an infant up to 1.5 years of age. that being said, do i need a booster or no as it provides lifetime protection?

Q: i have completed a 4-dose series of hepatitis vaccine when i was an infant up to 1.5 years of age. that being said, do i need a booster or no as it provides lifetime protection?

: Hepatitis A immunization gives lifelong protection. It's a bit less certain for hepatitis B. It can't hurt to have another dose, especially if you are at particular risk (sexual risks, injection drug use, etc). Or you can speak with your doctor about having a blood test for hepatitis B surface antibody (HBsAb); if undetectable or low, revaccination is recommended.

The CDC has recommended adults receive Hepatitis B vaccination. Please discuss with your physician whether you are eligible for the vaccination, based on your medical history. Update immunizations, including Influenza, if not. otherwise contraindicated.
