On June 17, 2024, the FDA approved the 21-valent pneumococcal conjugate vaccine (PCV21) for adults 18 and older, introducing eight new serotypes not in other vaccines.
The ACIP recommends PCV21 for all adults 65 and older, and for those aged 19-64 with specific health risks if they haven't been previously vaccinated or their vaccination status is unknown.
ACIP recommends a single dose of PCV21 for adults 19 and older, while maintaining previous indications and guidelines for other pneumococcal vaccines.
