Pfizer and BioNTech Join Forces to Develop Combination Influenza and COVID-19 Vaccine

Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) have announced positive topline results from a Phase 1/2 study evaluating the safety, tolerability and immunogenicity of mRNA-based combination vaccine candidates for influenza and COVID-19 among healthy adults 18 to 64 years of age. The data showed that the companies’ lead formulations demonstrated robust immune responses to influenza A, influenza B, and SARS-CoV-2 strains.

Annaliesa Anderson, PhD, FAAM, Senior Vice President and Head, Vaccine Research and Development at Pfizer, said, “This vaccine has the potential to lessen the impact of two respiratory diseases with a single injection and may simplify immunization practices for providers, patients, and healthcare systems all over the world.”

Prof. Ugur Sahin, MD, CEO and Co-founder of BioNTech, said, “Combination vaccines have the potential to become a mainstay of routine vaccination against respiratory diseases, especially for the vaccination of populations who have a higher risk of severe illness.”


The topline results of the ongoing trial demonstrated that the combination formulations evaluated had a safety profile consistent with the safety profile of the companies’ COVID-19 vaccine. Data from the Phase 1/2 trial will be published in a peer-reviewed journal.

 A pivotal Phase 3 trial evaluating these lead formulations is expected to be initiated in the coming months.

Pfizer and BioNTech previously announced that their mRNA-based combination vaccine candidate for influenza and COVID-19 received Fast Track Designation from the U.S. Food and Drug Administration (FDA).
