Abstract

20‑valent pneumococcal conjugate vaccine (PCV20; Prevnar 20; Apexxnar) is a pneumococcal conjugate vaccine (PCV) developed by Pfizer for active immunization for the prevention of pneumococcal infections. PCV20 has a similar structure and formulation to Pfizer's 13-valent PCV (PCV13; Prevnar 13; Prevenar 13), with the addition of polysaccharides to target seven further Streptococcus pneumoniae serotypes (8, 10A, 11A, 12F, 15B, 22F and 33F). PCV20 has been approved for active immunization for the prevention of pneumonia and invasive disease caused by S. pneumoniae in adults since June 2021 in the USA and since February 2022 in the EU. Following further evaluation of its safety, immunogenicity, and effectiveness in pediatric populations, in April 2023 PCV20 received its first pediatric approval, in the USA, for active immunization for the prevention of invasive pneumococcal disease (IPD) caused by S. pneumoniae serotypes 1, 3, 4, 5, 6A, 6B, 7F, 8, 9V, 10A, 11A, 12F, 14, 15B, 18C, 19A, 19F, 22F, 23F, and 33F in individuals 6 weeks to 17 years of age and for the prevention of otitis media caused by S. pneumoniae serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F in individuals 6 weeks to 5 years of age. This article summarizes the milestones in the development of PCV20 leading to this first pediatric approval for active immunization for the prevention of IPD and otitis media caused by S. pneumoniae.
