Pneumovax 23 Pneumococcal Vaccine

Pneumovax 23 Description

Merck's Pneumovax 23 (Pneumococcal Vaccine Polyvalent) is a vaccine that can help protect against infection by 23 types of pneumococcal bacteria, which are common and often cause serious illnesses.

Pneumovax 23 vaccine contains 23 serotypes (1, 2, 3, 4, 5, 6B, 7F, 8, 9N, 9V, 10A, 11A, 12F, 14, 15B, 17F, 18C, 19F, 19A, 20, 22F, 23F, and 33F).

Pneumovax 23 Indication

The pneumococcal disease includes pneumococcal infections of the lung, blood, and coverings of the brain and spinal cord. Pneumovax 23 will not prevent disease caused by capsular types of pneumococcus other than those contained in the vaccine.

Do not administer Pneumovax 23 to individuals with a history of a hypersensitivity reaction to any component of the vaccine.

Additionally, the U.S. CDC recommends Pneumovax 23 for people who have certain chronic conditions such as diabetes, heart disease, or COPD and who are 19 to 64 years old.

The global prevalence of the pneumococcal disease, an infection caused by bacteria called Streptococcus pneumoniae, is evolving, says the CDC. Highly aggressive strains, or serotypes, threaten to put more people at risk for non-invasive pneumococcal illnesses such as pneumonia (when it is confined to the lungs), sinusitis, and otitis media (middle ear infection); and invasive pneumococcal illnesses such as bacteremia (infection in the bloodstream), bacteremic pneumonia (pneumonia with bacteremia) and meningitis. 

Pneumovax 23 Dosage

Pneumovax 23 is administered as an intramuscular or subcutaneous injection only.

Pneumovax 23 is for people 50 years of age and older and is approved for persons aged ≥2 years who are at increased risk for pneumococcal disease. And if you are 65 years or older, even if you already had a dose of another vaccine before 65 for pneumococcal pneumonia, the U.S. CDC recommends you get Pneumovax 23.

The most common adverse reactions, reported in >10% of subjects vaccinated with PNEUMOVAX 23 in clinical trials, were: injection-site pain/soreness/tenderness, injection-site swelling/induration, headache, injection-site erythema, asthenia and fatigue, and myalgia.
