Quick overview

Prevnar 20 Injection (Pneumococcal 20-valent Conjugate Vaccine) is a bacterial vaccine used to help prevent pneumococcal disease, a serious infection that can affect the lungs, blood, brain, ears, and sinuses. It protects against 20 types of Streptococcus pneumoniae bacteria and is given as a shot into a muscle. Adults receive a single dose, while babies and children receive a series of four shots.

What is Prevnar 20 Injection

Prevnar 20 is a vaccine used to prevent pneumococcal disease, a serious bacterial infection that can affect the lungs (pneumonia), blood (bacteremia), brain (meningitis), ears, and sinuses. It protects against 20 types of Streptococcus pneumoniae bacteria. It is given as a shot into a muscle. Adults get one dose, while babies and children get a series of four shots.

Prevnar 20 Injection uses

  • Prevents invasive pneumococcal disease (such as blood or brain infections) in people 6 weeks of age and older
  • Prevents pneumonia (lung infection) caused by pneumococcal bacteria in people 18 years of age and older
  • Prevents ear infections (otitis media) caused by pneumococcal bacteria in children 6 weeks through 5 years of age

Benefits of Prevnar 20 Injection

  • Helps the body build immunity against 20 types of pneumococcal bacteria
  • Can reduce the risk of serious infections like meningitis, bacteremia, and pneumonia
  • Single-dose protection for adults 18 years and older

How Prevnar 20 Injection works

The vaccine exposes your body to a small part of the pneumococcal bacteria. This helps your immune system make antibodies so it can recognize and fight off the bacteria if you're exposed to them later. It does not treat an infection you already have.

Prevnar 20 Injection dosage

Prevnar 20 is given as an injection into a muscle by a healthcare provider. Adults 18 years and older receive a single dose. Infants and children receive a series of four doses, usually starting at 2 months of age and finishing between 12 and 15 months of age. If a dose or booster is missed, contact your vaccination provider as soon as possible; there is no need to start the series over. Keep up with other recommended childhood immunizations on their normal schedule, and follow your doctor's instructions about any restrictions on food, drinks, or activity around the time of vaccination.
