Pneumococcal Serotypes & Vaccine Coverage
pneumococcal disease is caused by the bacterium Streptococcus pneumoniae, which has over 90 different serotypes. Vaccines target specific serotypes, and the effectiveness of a vaccine depends on how well its serotype coverage matches the circulating strains in a given region.
| Vaccine | Serotype Coverage (Approximate) | Valency (Number of Serotypes) |
|---|---|---|
| Pneumococcal conjugate Vaccine (PCV13) | ~85-90% (in many regions) | 13 |
| Pneumococcal Polysaccharide Vaccine (PPSV23) | ~70-80% | 23 |
| Prevenar 20 | ~86% | 20 |
Note: Serotype coverage can vary depending on geographic location and circulating strains. Prevenar 20 includes serotypes not covered by PCV13, offering broader protection.
