Pneumococcal disease is an infection caused by a type of bacteria called Streptococcus pneumoniae. It can cause pneumonia, bloodstream infections, or meningitis. Pneumococcal disease is spread from person to person through coughing, sneezing, and close contact. Some people, especially children, can carry the bacteria in their nose and throat without being sick and can spread the bacteria to others.

Anybody can get pneumococcal disease, but some individuals are at higher risk of the infection or its complications than others.

Cancer patients are at higher risk, especially those undergoing stem cell transplant, CAR T cell therapy or other therapies that significantly suppress the immune system. They discuss timing of vaccination with their doctor-its recommended that vaccination occur 3-6 months following treatment.
