Dosage form: intramuscular injection

What is Prevnar 20?
Prevnar 20 is a vaccine used to prevent pneumococcal disease, a serious bacterial infection of the lungs (pneumonia), blood (bacteremia), brain (meningitis), ear infections, and sinus infections caused by pneumococcal bacteria. The Prevnar 20 vaccine protects against 20 types of Streptococcus pneumonia bacteria.
Prevnar vaccine is given as an injection into a muscle (intramuscular injection); adults have a single dose, and babies and children have a series of 4 shots.
Prevnar 20 works by exposing you to a small part of the bacteria, which helps your body develop immunity to bacteria. However, it will not treat an active infection that you already have.
Prevnar vaccine, like all vaccines, may not provide protection from disease in every person.
