The frequency of getting the pneumonia vaccine depends on age and health status. Infants typically get a series of four doses (at 2, 4, 6 months, and a booster at 12-15 months). For adults 65 years and older, one or two doses are recommended, and these usually last for life. People aged 2 to 64 with certain immune disorders or risk factors such as smoking may need one to three doses. If both PCV (pneumococcal conjugate vaccine) and PPSV (pneumococcal polysaccharide vaccine) are needed, they should be given several weeks apart. Re-vaccination depends on individual risk factors but generally is not annually required for most people.
Summary:
- Infants: 4-dose series.
- Age 65+: 1 or 2 doses, usually lifelong protection.
- Age 2-64 with risk factors: 1-3 doses as needed.
- No routine annual re-vaccination.
- Timing and number depend on vaccine type and health conditions.
This schedule covers routine vaccination and recommendations for at-risk groups, ensuring protection against pneumococcal diseases without unnecessary repeat doses.
