The frequency of getting a pneumonia shot depends on age and risk factors.
- For children younger than 2 years, a series of 4 doses is typical (at 2 months, 4 months, 6 months, and a booster between 12 and 15 months).
- Adults 65 years or older usually need one or two doses, which can protect for life, but a second dose may be recommended 1 to 5 years after the first depending on vaccine type and health status.
- Adults between 2 and 64 years old with certain immune disorders or risk factors might need one to three doses.
- Generally, most adults only require one or two pneumococcal shots in their lifetime, with boosters given as needed based on health conditions and previous vaccination history.
