Meningococcal disease and MenACWY vaccine

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

See meningococcal disease 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 MenACWY vaccine are sore arm, redness, or swelling and fever or irritability. A rare serious side effect is allergic-type reaction.
• The common symptoms and outcomes of meningococcal disease are meningitis or sepsis and death. A rare serious outcome is life-changing disability.
• By adjusting community vaccination rate, you can explore how herd immunity changes the probability of meningococcal disease in the model.
