Pneumococcal disease and pneumococcal vaccine

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

See pneumococcal 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 pneumococcal vaccine are soreness, low fever, or irritability and high fever or stomach upset. A rare serious side effect is allergic-type reaction.
• The common symptoms and outcomes of pneumococcal disease are pneumonia or ear infection and invasive disease. Rare serious outcomes include death and hearing loss or neurologic damage.
• By adjusting community vaccination rate, you can explore how herd immunity changes the probability of pneumococcal disease in the model.
