  • Two 25 μg doses of mRNA-1273 in participants 6 months to under 6 years met primary endpoint with robust neutralizing antibody titers similar to adults mRNA-1273 was generally well tolerated in this age group
  • Although not a primary endpoint, statistically significant vaccine efficacy was observed during the Omicron wave that was consistent with the lower two-dose effectiveness against Omicron seen in adults
  • Moderna is moving forward with global regulatory submissions for mRNA-1273 for primary vaccination of children 6 months to under 6 years of age
  • Additionally, Moderna has initiated a submission to the FDA for emergency use authorization of mRNA-1273 in children 6 to under 12 years of age; mRNA-1273 is approved for use in this age group in Europe, Canada and Australia

CAMBRIDGE, MA / ACCESSWIRE / March 23, 2022 / Moderna, Inc. (NASDAQ:MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today announced positive interim data from the Phase 2/3 KidCOVE study of the Moderna COVID-19 vaccine (mRNA-1273) in children 6 months to under 2 years and 2 years to under 6 years of age. This interim analysis showed a robust neutralizing antibody response in both age groups after a 25 µg two-dose primary series of mRNA-1273 along with a favorable safety profile. Based on these data, Moderna will submit a request for authorization of a 25 μg two-dose primary series of mRNA-1273 for children 6 months to under 6 years of age to the U.S. Food and Drug Administration (FDA), European Medicines Agency (EMA) and other global regulators in the coming weeks.

"We believe these latest results from the KidCOVE study are good news for parents of children under 6 years of age. We now have clinical data on the performance of our vaccine from infants six months of age through older adults," said Stéphane Bancel, Chief Executive Officer of Moderna. "Given the need for a vaccine against COVID-19 in infants and young children we are working with the U.S. FDA and regulators globally to submit these data as soon as possible. Additionally, after consultation with the U.S. FDA we have initiated a submission for emergency use authorization of our COVID-19 vaccine in children ages 6 to 11 years old and are updating our submission to the FDA for emergency use authorization of mRNA-1273 in adolescents ages 12 to 17 years with additional follow-up data. We remain committed to helping to end the COVID-19 pandemic with a vaccine for children of all ages."

KidCOVE is a randomized, observer-blind, placebo-controlled study to evaluate the safety, tolerability, and immunogenicity of two doses of mRNA-1273 given to healthy children 28 days apart. The study population is divided into three age groups (6 to
