Description
The pneumococcal vaccine protects against serious bacterial infections like pneumonia, meningitis, and sepsis caused by Streptococcus pneumoniae. Two primary categories exist: Pneumococcal Conjugate Vaccines (PCVs) like PCV13, PCV15, and PCV20, and Pneumococcal Polysaccharide Vaccines (PPSV23). Recommendations depend heavily on age and underlying health risks. [1, 2, 3, 4, 5]
Types of Pneumococcal Vaccines
- Conjugate Vaccines (PCV15, PCV20, PCV21): Trigger a robust immune response and are standard for infants, young children, and older adults.
Who Should Get Vaccinated
- Infants and Young Children: Routine childhood immunization schedules (such as Nigeria's National Programme on Immunization) include multiple priming doses of PCV starting at 6 weeks of age (at 6, 10, and 14 weeks) to prevent invasive pneumococcal disease.
- Adults Aged 65 and Older: Recommended for older adults who have not previously received a conjugate vaccine sequence.
- Individuals with High-Risk Conditions: Recommended for anyone aged 2 through 64 with chronic heart, lung, or liver disease, diabetes, cochlear implants, functional or anatomic asplenia, or weakened immune systems.
Possible Side Effects
- Mild soreness, redness, or swelling at the injection site.
- Low-grade fever or feeling tired for a day or two after receiving the shot.
