Measles and MMR vaccine

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

See measles 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 MMR vaccine are temporary fever or rash. Rare serious side effects include febrile seizure and severe allergic reaction.
• The common symptoms and outcomes of measles are acute measles illness and hospitalization. Rare serious outcomes include death, delayed neurological damage, and immune amnesia.
• By adjusting community vaccination rate, you can explore how herd immunity changes the probability of measles infection in the model.
