Does hepatitis b vaccine last for life?
I had my full course of Hep B vaccine as a child. A friend recently got a booster shot and now I'm confused. Does the Hepatitis B vaccine provide lifetime immunity or does its effect eventually wear off?

For most healthy people, once you complete the full course of 3 doses, it gives protection for at least 20 to 30 years, and often for life. There's no need to worry about boosters unless you work in a high-risk hospital setting.

I got super anxious thinking my childhood vaccine had expired and I was at risk. But my doctor smiled and explained that our immune system has a great memory and the protection usually lasts a lifetime for most people.

Don't just assume you are protected forever. I once assumed my old childhood vaccinations were enough for everything and neglected checking my health, which led to issues. Ask a doctor to do an antibody test if you are in doubt.

Yeah bro, basically if you got the full three shots when you were a kid, you are pretty much sorted for life. I had to get a blood test for my college admission and my Hep B immunity was still super strong.

According to my physician, clinical studies show that the immunological memory remains intact for at least 30 years after a full vaccine series. So even if antibody levels drop over time, you are generally still protected for life.
