Hepatitis B and hepatitis B vaccine

The app compares hepatitis B symptoms and outcomes with hepatitis B vaccine side effects, and shows how community vaccination (herd immunity) changes disease risk.

See hepatitis B risks, symptoms, and outcomes alongside vaccine side effects in the same model.

This is an educational simulation and does not provide medical advice or personalized risk assessment.

• The common side effects of the hepatitis B vaccine are local pain, myalgia, or brief fever. A rare serious side effect is severe allergic reaction.
• The common symptoms and outcomes of hepatitis B are no noticeable symptoms and acute hepatitis illness. Rare serious outcomes include fulminant liver failure, chronic infection with later liver damage risk, and death.
• By adjusting community vaccination rate, you can explore how herd immunity changes the probability of hepatitis B infection in the model.
