Hib and Hib vaccine

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

See Hib 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 Hib vaccine are pain, tenderness, or fever. A rare serious side effect is severe allergic reaction.
• The common symptoms and outcomes of Hib disease are meningitis, other invasive infection, and death. A rare serious outcome is hearing loss or brain damage.
• By adjusting community vaccination rate, you can explore how herd immunity changes the probability of Hib infection in the model.
