Pneumococcal Vaccines For 2022
Pneumococcal vaccines prevent pneumococcal disease caused by Streptococcus pneumoniae, a bacterium with more than 90 serotypes. And to prevent pneumonia, the U.S. FDA has approved two types of vaccines, PCV13, and PPSV23, protecting people from different types of pneumonia bacteria. Neither vaccine can prevent every kind of community-acquired pneumonia, but they work against the 30 most common bacteria types.
The U.S. CDC's pneumococcal vaccine schedules were updated on February 17, 2022, and the clinical practice guidelines on pneumococcal vaccination were published on January 28, 2022. For children 2-18 years old with underlying medical conditions, when both PCV13 and PPSV23 are indicated, however, the two vaccines should not be administered simultaneously. Furthermore, the CDC recommends that all adults 65 years and older and adults with underlying medical conditions receive one dose of PCV15 or one dose of PCV20.
On June 22, 2022, the CDC's ACIP committee presented the following information: PCV15 Pediatric Clinical Development Program – Dr. N Banniettis; Economic analysis and public health impact of PCV15 use among children in the US - Dr. A Leidner; Summary of WG interpretation on EtR and Proposed recommendations for PCV15 use in children by Dr. M Kobayashi.
