Drug class: Vaccine (Pneumococcal Conjugate Vaccine)

Overview

Prevnar 20 (PCV20) is a vaccine that helps protect against 20 different types of Streptococcus pneumoniae bacteria, which can cause serious infections such as pneumonia, meningitis, and bloodstream infections (sepsis). It is used in both adults and children to reduce the risk of pneumococcal disease. The vaccine works by stimulating your immune system to produce antibodies against the bacteria, so your body can recognize and fight off the infection if you are exposed in the future. Prevnar 20 is given as an injection, usually in the upper arm or thigh. Key points to know: Prevnar 20 does not treat active infections and is most effective when given before exposure to pneumococcal bacteria. It is recommended for infants, older adults, and people with certain health conditions that increase their risk of pneumococcal disease.
