Moderna, Inc. (Nasdaq: MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today announced a new supply agreement with the Swiss Federal Government for 7 million doses of booster vaccine in 2022, with an additional option for another 7 million doses for delivery during the second half of 2022 or first quarter of 2023. Purchase under this agreement is subject to regulatory approval of the booster vaccine candidate. Today’s announcement follows two earlier agreements between Switzerland and Moderna to supply a total of 13.5 million doses of the COVID-19 Vaccine Moderna. Swissmedic, the Swiss Agency for Therapeutic Products, authorized the COVID-19 Vaccine Moderna in Switzerland on January 12, 2021.
“We appreciate the partnership of the Swiss Federal Government, and their continued support demonstrated by this new supply agreement for doses of Moderna variant booster candidates,” said Stéphane Bancel, Chief Executive Officer of Moderna. “We are encouraged by the new data, which reinforce our confidence that our booster strategy should be protective against these newly detected variants and we will continue to make as many updates to our COVID-19 vaccine as necessary to control the pandemic.”
Initial data from Moderna’s Phase 2 study in the U.S. showed that a single 50 µg dose of mRNA-1273 or mRNA-1273.351 given as a booster to previously vaccinated individuals increased neutralizing antibody titer responses against SARS-CoV-2 and two variants of concern, B.1.351 (first identified in South Africa) and P.1 (first identified in Brazil). A dose of mRNA-1273.351, the Company’s strain-matched booster, achieved higher neutralizing antibody titers against the B.1.351 variant of concern than a booster dose of mRNA-1273. Safety and tolerability profiles following third dose booster injections of 50 µg of mRNA-1273 or mRNA-1273.351 were generally comparable to those observed after the second dose of mRNA-1273 in the previously reported Phase 2 and Phase 3 studies. A manuscript describing these preliminary results has been submitted as a preprint to bioRxiv and will be submitted for peer-reviewed publication upon completion of the multivalent mRNA-1273.211 booster arm.
