Uses for Prevnar 20

Pneumococcal 20-valent conjugate vaccine is an active immunizing agent used to prevent infection caused by certain types of pneumococcal bacteria (Streptococcus pneumoniae). It works by causing your body to produce its own protection (antibodies) against the disease.

Pneumococcal infection can cause serious problems, such as pneumonia (which affects the lungs), meningitis (which affects the brain), bacteremia (which is a severe infection in the blood).

This vaccine is to be given only by or under the supervision of your doctor.
