Pfizer and BioNTech Publish Data on COVID-19 Vaccine-Induced Antibodies’ Ability to Neutralize SARS-CoV-2 U.K. Strain Pseudovirus in Cell Culture in Science

Mainz: Pfizer Inc. (NYSE: PFE) and BioNTech SE (Nasdaq: BNTX) today announced that data from an in vitro study on the capability of sera from individuals immunized with the Pfizer-BioNTech COVID-19 vaccine BNT162b2 to neutralize a pseudovirus bearing the SARS-CoV-2 U.K. variant, also known as B.1.1.7 lineage, were published in the journal Science. Some of these data were initially made available to the public on January 20, 2021 via the online preprint server, bioRxiv. The study published today includes a larger number of sera from vaccinated individuals and confirms the initial study results that the B.1.1.7 lineage is unlikely to escape BNT162b2-mediated protection. For additional details, please read the previously issued press release.
