Purpose

CIRV2 is a Phase IV randomized, open-label, trial of FDA-approved COVID-19 and/or influenza vaccines (no more than minimal risk) with longitudinal follow-up. In 2025 CIRV2 will compare immunogenicity and reactogenicity of the recombinant Novavax COVID-19 vaccine and the mRNA Pfizer-BioNTech COVID-19 vaccine.

Detailed Description

The goal of the Comparative Immunogenicity of Respiratory Virus Vaccines (CIRV2) study is to conduct, on a yearly basis, direct comparisons of immunogenicity and reactogenicity of the most recent versions of FDA-approved vaccines for COVID-19 and/or influenza. Studies will be conducted on individuals that are FDA eligible to receive these vaccines and do not have a medical condition that severely impairs their immune system. For 2025, the study will directly compare the immunogenicity and reactogenicity of the 2025 Novavax recombinant COVID-19 vaccine with the 2025 Pfizer/BioNTech mRNA COVID-19 vaccine.
