• Filing follows approval of Spikevax bivalent Original/Omicron BA.1 (mRNA-1273.214), a bivalent booster vaccine targeting the Omicron BA.1 subvariant, in September
• Moderna's Omicron-targeting bivalent boosters now authorized in the United States, Australia, Canada, Europe, Japan, South Korea, Switzerland, Singapore, Taiwan, and the UK

Moderna, Inc. (NASDAQ:MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today announced that the European Medicines Agency (EMA) has accepted a variation for the evaluation of a 50 µg booster dose of the Omicron-containing bivalent COVID booster candidate, mRNA-1273.222 (Spikevax bivalent Original/Omicron BA.4-5) in adults 12 years and older. Spikevax bivalent Original/Omicron BA.4-5 is a next-generation bivalent vaccine that contains 25 µg of mRNA-1273 (Spikevax) and 25 µg of a vaccine candidate targeting the Omicron variant of concern (BA.4/BA.5).

"We are proud to announce this filing for the use of our bivalent COVID-19 vaccine targeting the BA.4/BA.5 Omicron subvariants in the European Union," said Stéphane Bancel, Chief Executive Officer of Moderna. "Following the recent approval of our BA.1 targeting vaccine in Europe, our BA.4/BA5 Omicron targeting vaccine will now bring a second option to help protect people across Europe as we head into the winter months."

mRNA-1273.222 targets both the original strain of SARS-CoV-2 as well as the BA.4/BA.5 subvariants of the Omicron strain. Moderna's submission to the EMA is based on preclinical data for mRNA-1273.222 as well as clinical trial data from a Phase 2/3 studying Spikevax bivalent Original/Omicron BA.1 (mRNA-1273.214), a bivalent booster vaccine targeting the Omicron BA.1 subvariant, which recently received EMA approval.

Moderna has received authorizations for Omicron-targeting bivalent boosters in the United States, Australia, Canada, Europe, Japan, South Korea, Switzerland, Singapore, Taiwan, and the UK to date and has submitted regulatory applications worldwide.
