CHMP recommends approval of Omicron XBB.1.5-adapted monovalent COVID-19 vaccine for Coronavirus

The Committee has also recommended the updated vaccine for children 6 months through 4 years of age as part or all of the primary three-dose vaccination series, depending on how many prior doses they received, or as single dose for those with a history of completion of a COVID-19 primary vaccination course or prior SARS-CoV-2 infection.

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 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.
