Moderna Announces FDA Advisory Board Votes Unanimously for Emergency Use of Moderna’s COVID-19 Vaccine Booster Dose in the United States | 2021-10-14 | Press Releases



Unanimous positive vote for the recall of mRNA-1273 at the dose level of 50 µg for people aged 65 and over as well as those aged 18 to 64 at high risk of contracting COVID-19 at least 6 months after the end of the primary series

Company estimates that a booster at the 50 µg dose level could result in up to 1 billion additional doses

Moderna, Inc. (Nasdaq: MRNA), a pioneering biotechnology company in messenger RNA (mRNA) therapies and vaccines, today confirmed that the Vaccines and Related Biologics Advisory Board (VRBPAC) of The United States Food and Drug Administration (FDA) has recommended that the FDA grant an Emergency Notice of Authorization for Use (EUA) for a booster dose of Moderna COVID-19 vaccine (mRNA-1273) at the dose level 50 µg for people aged 65 and over; people aged 18 to 64 who are at high risk of severe COVID-19; and people aged 18 to 64 whose exposure to COVID-19 puts them at risk of complications from COVID-19 or serious illness. The positive vote was unanimous with 19 VRBPAC members recommending the EUA. The booster dose should be given at least six months after the end of the primary vaccination course.

“We are grateful for the opportunity to present the clinical data set for our COVID-19 booster vaccine to the FDA advisory committee today.” We thank the committee for its review and for its positive recommendation in support of the emergency use authorization. This positive recommendation is supported by data on the 50 µg booster dose of our COVID-19 vaccine, which shows strong antibody responses against the original virus, but also against the Delta variant, ”said Stéphane Bancel, Managing Director of Moderna. “We remain committed to staying one step ahead of the virus and to monitoring the evolving epidemiology of SARS-CoV-2. We look forward to making our booster available to people in the United States to help protect themselves against this ongoing public health emergency. ”

VRBPAC based its recommendation on the body of scientific evidence, including an analysis of data from the Phase 2 clinical study of mRNA-1273, which was modified to provide a booster dose of mRNA-1273 at the 50 µg dose level to interested participants 6-8 months after their second dose (n = 344). Neutralizing antibody titers had decreased prior to the booster, particularly against the variants of concern, to approximately 6 months. Notably, a booster dose of mRNA-1273 at the dose level of 50 µg increased the neutralizing titers significantly above the phase 3 baseline. After a booster dose, a similar level of neutralizing titers was achieved. in all age groups, especially the elderly (65 years and over). The safety profile after the booster dose was similar to that observed previously for dose 2 mRNA-1273.

Moderna estimates that the positive vote for mRNA-1273 at the 50 µg dose level and subsequent approval could result in up to 1 billion additional doses available for distribution in 2022.

FDA advisory committees provide non-binding recommendations. The FDA will take VRBPAC’s recommendation into consideration when making a final clearance decision. Under an EUA, the FDA has the authority to authorize the use of unapproved medical products or unapproved uses of approved medical products in an emergency to diagnose, treat or prevent serious illnesses or conditions. or potentially fatal in a declared public health emergency when there are no adequate, approved and available alternatives. Next, the U.S. Centers for Disease Control and Prevention’s (CDC) Immunization Practices Advisory Committee (ACIP) will meet to discuss their recommendations regarding the use of COVID-19 boosters.

Separately, on August 13, Moderna announced that the US FDA had approved an update to the emergency use authorization for the Moderna COVID-19 vaccine to include a third dose at the 100 µg dose level. for immunocompromised persons 18 years of age or older in the United States. Conditions that have undergone a solid organ transplant, or that are diagnosed with conditions that are considered to have an equivalent level of immunosuppression.

About Moderna

In the 10 years since its inception, Moderna has grown from a company in the scientific research stage advancing programs in the field of messenger RNA (mRNA), to a company with a diverse clinical portfolio of vaccines and therapeutic products. through six modalities, a broad portfolio of intellectual property in areas such as the formulation of mRNA and lipid nanoparticles, and an integrated manufacturing facility that enables both clinical and commercial production on a large scale and at low speed. previous. Moderna maintains alliances with a wide range of domestic and foreign government and business collaborators, which has allowed the pursuit of both groundbreaking science and rapid scale-up of manufacturing. More recently, Moderna’s capabilities have come together to enable the licensed use of one of the oldest and most effective vaccines against the COVID-19 pandemic.

Moderna’s mRNA platform builds on continuous advancements in basic and applied mRNA science, delivery technology and manufacturing, and has enabled the development of therapies and vaccines for them. infectious diseases, immuno-oncology, rare diseases, cardiovascular diseases and autoimmune diseases. Moderna was named one of the top biopharmaceutical employers by Science for six years. To learn more, visit
