Mumps and MMR vaccine

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

See mumps 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 mumps are no noticeable symptoms and swollen glands and fever illness. Rare serious outcomes include meningitis or pancreatitis and brain inflammation or hearing loss.
• By adjusting community vaccination rate, you can explore how herd immunity changes the probability of mumps infection in the model.
