Pfizer, BioNTech receive positive CHMP opinion for Omicron XBB.1.5-adapted COVID vaccine in EU

The European Commission (EC) will review the CHMP’s recommendation and is expected to make a final decision soon. Following a decision from the EC, the updated vaccine will be ready to ship to applicable EU member states immediately. Pfizer and BioNTech have been manufacturing the Omicron XBB.1.5-adapted monovalent COVID-19 vaccine at risk to ensure supply readiness ahead of the upcoming fall and winter season when the demand for COVID-19 vaccination is expected to increase.

“This season’s vaccine is ready to ship as soon as the final regulatory decision is made, so that people across Europe can better help protect themselves against COVID-19 illness as the risk rises,” said Albert Bourla, Chairman and Chief Executive Officer at Pfizer. “It's been nearly a year since many citizens in the European Union were vaccinated against COVID-19 and the updated formulation provides the opportunity for them to receive a vaccine more closely matched to current sublineages."

“As COVID-19 is expected to adopt a seasonal pattern, similar to other respiratory viruses, we remain committed to providing COVID-19 vaccines that are better matched to relevant circulating variants or sublineages to people worldwide, to support vaccinations in the upcoming fall and winter season,” said Prof. Ugur Sahin, M.D., CEO and Co-founder of BioNTech. “Omicron XBB-related sublineages are antigenically distant from prior Omicron strains and continue to account for the vast majority of COVID-19 cases globally. The updated COVID-19 vaccine aims to further improve protection against severe illness and hospitalization.”

The CHMP’s recommendation is based on the full body of previous clinical, non-clinical, and real-world evidence supporting the safety and efficacy of the COVID-19 vaccines by Pfizer and BioNTech. Further, the application included pre-clinical data showing that the Omicron XBB.1.5-adapted monovalent COVID-19 vaccine generates a substantially improved response against multiple XBB sublineages, including XBB.1.5, XBB.1.16, and XBB.2.3, compared to the Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine. Additional pre-clinical data demonstrate that serum antibodies induced by the updated COVID-19 vaccine, when compared to the Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine, also effectively neutralize the globally dominant and recently WHO-designated variant of interest EG.5.1 (Eris).

Pfizer and BioNTech have also filed an application with the U.S. Food and Drug Administration (FDA) requesting approval of their Omicron XBB.1.5-adapted monovalent COVID-19 vaccine for individuals 6 months of age and older. A decision is expected in the coming days. The companies have submitted data for the updated COVID-19 vaccine to other regulatory authorities around the world.

The COVID-19 vaccines (COMIRNATY) by Pfizer and BioNTech are based on BioNTech’s proprietary mRNA technology and were developed by both companies. BioNTech is the Marketing Authorization Holder for COMIRNATY and its adapted vaccines (COMIRNATY Original/Omicron BA.1; COMIRNATY Original/Omicron BA.4/BA.5) in the United States, the European Union, the United Kingdom, Canada and other countries, and the holder of emergency use authorizations or equivalents in the United States (jointly with Pfizer) and other countries.
