Moderna, Inc. (NASDAQ:MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today announced that the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion recommending a variation to the conditional marketing authorization (CMA) to include a booster dose of Spikevax, the Company's COVID-19 vaccine, at the 50 µg dose level for adolescents (12-17 years) at least three months after completion of the primary series.

"The recommendation to authorize the use of a booster dose of Spikevax in adolescents ages 12-17 is an important step to continue to protect this age group from COVID-19 and the the emergence of new variants of concern," said Stéphane Bancel, Chief Executive Officer of Moderna. "We are grateful to the CHMP for their comprehensive review of our submission and look forward to an authorization decision from the European Commission."

The CHMP based this positive opinion on scientific evidence shared by the company, including comprehensive safety data. The administration of a booster dose of 50 µg at least three months after administration of completion of the primary series is predicted to substantially increase the immune responses against variants of concern, including Omicron compared to pre-boost levels.

Authorized Use

Spikevax (elasomeran mRNA vaccine) has been granted Conditional Marketing Authorization by the European Commission, based upon the recommendation of the European Medicines Agency and is indicated for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 in individuals six years of age and older. A booster dose may be given at least three months after the second dose for people aged 12 years and older.

About Moderna

In 10 years since its inception, Moderna has transformed from a science research-stage company advancing programs in the field of messenger RNA (mRNA), to an enterprise with a diverse clinical portfolio of vaccines and therapeutics across seven modalities, a broad intellectual property portfolio in areas including mRNA and lipid nanoparticle formulation, and an integrated manufacturing plant that allows for rapid clinical and commercial production at scale. Moderna maintains alliances with a broad range of domestic and overseas government and commercial collaborators, which has allowed for the pursuit of both ground-breaking science and rapid scaling of manufacturing. Most recently, Moderna's capabilities have come together to allow the authorized use and approval of one of the earliest and most-effective vaccines against the COVID-19 pandemic.

Moderna's mRNA platform builds on continuous advances in basic and applied mRNA science, delivery technology and manufacturing, and has allowed the development of therapeutics and vaccines for infectious diseases, immuno-oncology, rare diseases, cardiovascular diseases, and auto-immune diseases. Moderna has been named a top biopharmaceutical employer by Science for the past seven years. To learn more, visit www.modernatx.com.
