Typhoid and typhoid vaccine

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

See typhoid 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 typhoid vaccine are fever, pain, or swelling. A rare serious side effect is severe allergic reaction.
• The common symptoms and outcomes of typhoid are typhoid fever illness, hospitalization, and death. A rare serious outcome is chronic carrier state.
• By adjusting community vaccination rate, you can explore how herd immunity changes the probability of typhoid infection in the model.
