Moderna, Inc.: Moderna Receives FDA Approval for Emergency Use Authorization of 2nd Booster Dose of Its COVID-19 Vaccine, mRNA-1273

50 µg dose approved for all adults over 50 years of age and immunocompromised adults over 18 years of age

CAMBRIDGE, MA / ACCESSWIRE / March 29, 2022 / Moderna, Inc. (NASDAQ:MRNA), a biotechnology company pioneering messenger RNA (mRNA) therapeutics and vaccines, announced today that it has received approval from the U.S. Food and Drug Administration (FDA) for its amendment to the emergency use authorization (EUA) to allow for a second booster dose of its COVID-19 vaccine (mRNA-1273) at the 50 µg dose level in adults 50 years of age and older who have received an initial booster of any of the authorized or approved COVID-19 vaccines and adults 18 years of age and older with certain kinds of immunocompromise.

"The FDA's endorsement of a second booster dose will allow millions of Americans to build and maintain protection against SARS-CoV-2," said Stéphane Bancel, Chief Executive Officer of Moderna. "The virus continues to evolve, and we are currently on the verge of another potential wave driven by the BA.2 variant. Data continue to show that mRNA boosters remain the best defense against severe infection and death, and vaccines are a foundational part of our public health protection. Now, healthcare providers have the opportunity to advise higher-risk people about when and how to get boosted and build immunity in advance of future outbreaks."

The application to amend the EUA has been based on published data from Israel indicating the safety and effectiveness of administering a fourth dose of mRNA vaccine during the Omicron variant surge.

On January 31, 2022, the U.S. FDA approved the Biologics License Application (BLA) for SPIKEVAX (COVID-19 Vaccine, mRNA) to prevent COVID-19 in individuals 18 years of age and older. Previously, Moderna's COVID-19 vaccine was available under EUA in the U.S. from December 18, 2020. A booster dose of the Moderna COVID-19 vaccine at the 50 µg dose level is authorized for emergency use in the U.S. under EUA for adults 18 years and older. A third dose of the Moderna COVID-19 vaccine at the 100 µg dose level is authorized for emergency use in immunocompromised individuals 18 years of age with certain kinds of immunocompromise.

Moderna continues to collect and monitor real-world data on its COVID-19 vaccine. Real-world evidence continues to confirm the effectiveness and robust safety profile of the Moderna COVID-19 vaccine. Clinical trials are ongoing for Moderna's Omicron-specific booster (mRNA-1273.529) and a bivalent Omicron-specific booster (mRNA-1273.214).

INDICATION (U.S.)

SPIKEVAX (COVID-19 Vaccine, mRNA) is a vaccine indicated 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 to individuals with a known history of severe allergic reaction (e.g., anaphylaxis) to any component of the 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 vaccine.
• Postmarketing data demonstrate increased risks of myocarditis and pericarditis, particularly within 7 days following the second dose. The observed risk is higher among males under 40 years of age than among females and older males. The observed risk is highest in males 18 through 24 years of age.
• 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 vaccine.
• The vaccine may not protect all vaccine recipients.
• Adverse reactions reported in clinical trials following administration of the 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.
• The vaccination provider is responsible for mandatory reporting of certain adverse events to the Vaccine Adverse Event Reporting System (VAERS) online at https://vaers.hhs.gov/reportevent.html or by calling 1-800-822-7967.
