Moderna Announces FDA Authorization of a Booster Dose of Moderna’s COVID-19 Vaccine in the U.S.

• Emergency Use Authorization (EUA) granted for individuals 65 years of age and older, and individuals ages 18 through 64 within certain high-risk groups
• FDA also authorized the use of Moderna’s booster dose following primary vaccination with other authorized or approved COVID-19 vaccines

CAMBRIDGE, Mass.--Oct. 20, 2021-- Moderna, Inc. (Nasdaq:MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, today announced that the U.S. Food and Drug Administration (FDA) has authorized for emergency use a booster dose of the Moderna COVID-19 vaccine (mRNA-1273) at the 50 µg dose level for people aged 65 and older; people aged 18 to 64 who are at high risk of severe COVID-19; and people aged 18 to 64 with frequent institutional or occupational exposure to SARS-CoV-2. The booster dose is to be administered at least six months after completion of the primary series. The FDA also authorized a single booster dose of the Moderna COVID-19 Vaccine for individuals who have completed a primary vaccination with other authorized or approved COVID-19 vaccines.

“This emergency use authorization is supported by robust clinical evidence that a 50 µg booster dose induces a strong immune response against COVID-19. We thank the FDA for their review and for this EUA including for those people who have completed a primary vaccination with a different COVID-19 vaccine,” said Stéphane Bancel, Chief Executive Officer of Moderna. “We believe that mRNA vaccines are uniquely positioned to adapt to the evolving epidemiology of SARS-CoV-2. We’re grateful for the opportunity to provide individuals with another layer of protection.”

The FDA based this EUA on the totality of scientific evidence shared by the company and reviewed by the FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC), including a data analysis from the Phase 2 clinical study of mRNA-1273, which was amended to offer a booster dose of mRNA-1273 at the 50 µg dose level to interested participants 6-8 months following their second dose (n=344). Neutralizing antibody titers had waned prior to boosting, particularly against variants of concern, at approximately 6 months. Notably, a booster dose of mRNA-1273 at the 50 µg dose level boosted neutralizing titers significantly above the Phase 3 benchmark. After a booster dose, a similar level of neutralizing titers was achieved across age groups including in older adults (ages 65 and above). The safety profile following the booster dose was similar to that observed previously for dose 2 of mRNA-1273. The positive vote was unanimous with 19 VRBPAC members recommending EUA.

As a next step, the U.S. Centers for Disease Control and Prevention’s (CDC) Advisory Committee on Immunization Practices (ACIP) will meet to discuss a potential recommendation for the use and rollout of COVID-19 boosters to Americans.

AUTHORIZED USE IN THE US

Moderna COVID-19 Vaccine is authorized for use under an Emergency Use Authorization (EUA) for active immunization to prevent coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in individuals 18 years of age and older.

IMPORTANT SAFETY INFORMATION

• Do not administer the Moderna COVID-19 Vaccine to individuals with a known history of severe allergic reaction (e.g., anaphylaxis) to any component of the Moderna COVID-19 Vaccine.
• Appropriate medical treatment to manage immediate allergic reactions must be immediately available in the event an acute anaphylactic reaction occurs following administration of the Moderna COVID-19 Vaccine. Monitor the Moderna COVID-19 Vaccine recipients for the occurrence of immediate adverse reactions according to the Centers for Disease Control and Prevention guidelines (https://www.cdc.gov/vaccines/covid-19/clinical-considerations/managing-anaphylaxis.html).
• Postmarketing data demonstrate increased risks of myocarditis and pericarditis, particularly within 7 days following the second dose.
• Syncope (fainting) may occur in association with administration of injectable vaccines. Procedures should be in place to avoid injury from fainting.
• Immunocompromised persons, including individuals receiving immunosuppressive therapy, may have a diminished response to the Moderna COVID-19 Vaccine
• The Moderna COVID-19 Vaccine may not protect all vaccine recipients.
• Adverse reactions reported in clinical trials following administration of the Moderna COVID-19 Vaccine include pain at the injection site, fatigue, headache, myalgia, arthralgia, chills, nausea/vomiting, axillary swelling/tenderness, fever, swelling at the injection site, and erythema at the injection site, and rash.
• Anaphylaxis and other severe allergic reactions, myocarditis, pericarditis, and syncope have been reported following administration of the Moderna COVID-19 Vaccine during mass vaccination outside of clinical trials.
• Available data on the Moderna COVID-19 Vaccine administered to pregnant women are insufficient to inform vaccine-associated risks in pregnancy. Data are not available to assess the effects of the Moderna COVID-19 Vaccine on the breastfed infant or on milk production/excretion.
• Additional adverse reactions, some of which may be serious, may become apparent with more widespread use of the Moderna COVID-19 Vaccine.
• Vaccination providers must complete and submit reports to VAERS online at https://vaers.hhs.gov/reportevent.html. For further assistance with reporting to VAERS, call 1-800-822-7967. The reports should include the words “Moderna COVID-19 Vaccine EUA” in the description section of the report.
