Moderna announced a supply agreement with the UK government for an additional two million doses of mRNA-1273, Moderna’s vaccine candidate against COVID-19, to the United Kingdom beginning in March 2021. The UK government has now secured seven million doses of mRNA-1273. This confirmation comes as the UK continues its efforts to secure access to safe and effective COVID-19 vaccines by establishing a broad portfolio of the most promising vaccines.

On November 16, Moderna announced that the independent, NIH-appointed Data Safety Monitoring Board (DSMB) for the Phase 3 study of mRNA-1273, its vaccine candidate against COVID-19, has informed Moderna that the trial has met the statistical criteria pre-specified in the study protocol for efficacy, with a vaccine efficacy of 94.5 per cent. This study, known as the COVE study, enrolled more than 30,000 participants in the U.S. and is being conducted in collaboration with the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), and the Biomedical Advanced Research and Development Authority (BARDA), part of the Office of the Assistant Secretary for Preparedness and Response at the US Department of Health and Human Services.

Moderna has also received confirmation that the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom started the rolling review process of mRNA-1273.
