Randomized trial to evaluate the safety, tolerability, and immunogenicity of a booster (third dose) of BNT162b2 COVID-19 vaccine coadministered with 20-valent pneumococcal conjugate vaccine in adults ≥65 years old.

ABSTRACT:

Background

Older adults are at increased risk of adverse outcomes from pneumococcal disease and COVID-19. Vaccination is an established strategy for preventing both illnesses. This study evaluated the safety and immunogenicity of coadministration of the 20-valent pneumococcal conjugate vaccine (PCV20) and a booster (third dose) of BNT162b2 COVID-19 vaccine.

Methods

This phase 3, randomized, double-blind, multicentre study included 570 participants aged ≥65 years randomized 1:1:1 to PCV20 and BNT162b2 coadministered, or PCV20 or BNT162b2 only (administered with saline for blinding). Primary safety endpoints included local reactions, systemic events, adverse events (AEs) and serious AEs (SAEs). Secondary objectives were immunogenicity of PCV20 and BNT162b2 when administered to
