evidence: NEW YORK & MAINZ, Germany--(BUSINESS WIRE)-- Pfizer Inc. (NYSE: PFE, "Pfizer") and BioNTech SE (Nasdaq: BNTX, "BioNTech") today announced top-line results from their Phase 3 clinical trial to evaluate the companies’ combined mRNA vaccine candidate against influenza and COVID-19 in healthy individuals 18-64 years of age. The combination candidate consists of Pfizer’s mRNA-based influenza vaccine candidate with the companies’ licensed COVID-19 vaccine. The Phase 3 trial measured two primary immunogenicity objectives (immunogenicity against SARS-CoV-2 as well as immunogenicity against influenza A and B), of which one was met. In a separate Phase 2 trial, Pfizer evaluated trivalent ("tIRV") influenza mRNA standalone vaccine candidates which demonstrated robust immunogenicity in individuals 18-64 years of age. The companies are evaluating adjustments to the combination vaccine candidate aimed at improving immune responses against influenza B and will discuss next steps with health authorities. [...] Additional side effects that have been reported with COMIRNATY or Pfizer-BioNTech COVID-19 vaccines include:
