HelixTalk #152 - Strain-ger Things: Pneumococcal Vaccine Updates
Date posted: August 16, 2022, 6:00 am
In this episode, we will discuss the rationale behind the FDA approval of two new pneumococcal conjugate vaccines (PCV20 and PCV15), the characteristics of these vaccines, their place in therapy as recommended by the ACIP, and subsequent CDC immunization schedule changes.
- Pneumococcal disease is mainly caused by various serotypes of Streptococcus pneumoniae and presentation can vary from mild forms (sinusitis, otitis media) to more severe (pneumonia, bacteremia, or meningitis).
- Previously we used PCV13 and PPSV23 vaccines for adults ages 18 years and older for prevention of pneumococcal disease, but the recommendations were rather complicated based on age, underlying condition/immune status, and vaccination status.
- Two new conjugate-type pneumococcal vaccines, PCV20 (Prevnar 20) and PCV15 (Vaxneuvance) are now approved by the FDA and were recently added to the CDC’s adult immunization schedules.
- These updated recommendations are more simplified where adults with high-risk conditions and those ages 65 years and older should receive either 1 dose of PCV20 vaccine or 1 dose of PCV15 and then 1 dose of PPSV23 a year later to complete their pneumococcal vaccine series.
- PCV15 is now FDA approved for children and updated recommendations for children have been voted upon by the Advisory Committee on Immunization Practices (ACIP) and will be final once it is made official policy by the CDC.
