What is pneumococcal polysaccharides vaccine (PPSV)?

Pneumococcal disease is a serious infection caused by bacteria called pneumococcus. It can infect the blood, lungs, and the area around the brain and spinal cord. These infections can be fatal.

Pneumococcal polysaccharides vaccine (PPSV) is used to help prevent disease caused by 23 types of pneumococcal bacteria, which are included in the vaccine.

PPSV is for adults 50 years and older, and for adults and children who are at least 2 years old and have a higher risk of developing pneumococcal disease due to certain medical conditions.

This vaccine helps your body build immunity to the disease, but it will not treat an active infection you already have.

Like any vaccine, pneumococcal polysaccharides vaccine may not protect every person from disease.
