Pneumonia Vaccine Dosage

The recommended dosage of the pneumonia vaccine will depend on your age, your risk factors, and whether you are receiving Prevnar 13 or Pneumovax. For example, most children receiving Prevnar 13 will require four separate injections. With Pneumovax, the standard dose for most adults is one injection (a second one may be recommended in certain cases).

An Introduction to Dosing With the Pneumonia Vaccine

There are two different pneumonia vaccines currently available -- Pneumovax® and Prevnar 13®. For each vaccine, there is only one standard recommended dosage, although the precise schedules may vary depending on things like age and risk factors.
People who fall into the recommended categories for both vaccines can (and often should) receive both of them.

Schedule for Pneumovax Dosages

For most people, only one dose of this pneumonia vaccine is recommended. The standard pneumonia vaccine dosage is 0.5 mL, injected into a muscle (intramuscularly) or just under the skin (subcutaneously).
However, people who remain at high risk of pneumococcal diseases such as pneumonia may need a second dosage if it has been five years or more since the first one. People who should receive a second injection include:
  • People age 65 and older who had the first dose before the age of 65
  • People age 2 though 64 years who:
    • Have a damaged spleen or no spleen
    • Have sickle cell disease
    • Have HIV or AIDS
    • Have cancer, leukemia, lymphoma, or multiple myeloma
    • Have nephritic syndrome
    • Have had a bone marrow transplant or organ transplant
    • Are taking immune-suppressing medications.
