Pfizer Inc. (NYSE: PFE) will share data across its expansive infectious disease portfolio, including company-sponsored and collaborative research studies, spanning both licensed and investigational vaccines, and antibiotic and antiviral therapies at IDWeek 2022 held in Washington, D.C. October 19-23, 2022. Data from 35 abstracts involving Pfizer vaccines and anti-infective therapies will illustrate the diversity of the portfolio and the company’s cutting-edge scientific approach. This will include a late-breaking presentation of the full data from its Phase 3 (NCT05035212) RENOIR (RSV vaccine Efficacy study iN Older adults Immunized against RSV disease) clinical trial, investigating its bivalent RSV A and B, stabilized RSV prefusion F subunit vaccine candidate, RSVpreF, when administered to adults 60 years of age and older. These data will also be presented on October 20, 2022, to the U.S. Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP).
