Moderna, Inc.: Moderna Receives U.S. FDA Approval for Updated 2026-2027 COVID-19 Vaccines

CAMBRIDGE, MA / ACCESS Newswire / August 27, 2026 / Moderna, Inc. (NASDAQ:MRNA) today announced that the U.S. Food and Drug Administration (FDA) has approved the supplemental Biologics License Applications (sBLA) for the 2026-2027 formulas for Spikevax (COVID-19 Vaccine, mRNA) and mNEXSPIKE (COVID-19 Vaccine, mRNA), containing the JN.1-lineage XFG subvariant of SARS-CoV-2 to help prevent COVID-19.

The updated formula for Spikevax is now approved for individuals 6 months through 64 years of age with at least one underlying condition placing them at high risk for severe outcomes from COVID-19, and all adults 65 years of age and older. mNEXSPIKE, Moderna's latest COVID-19 vaccine, is approved for individuals 12 through 64 years of age with at least one underlying condition that puts them at high risk for severe outcomes from COVID-19, and all adults 65 years of age and older.

"COVID-19 remains a serious public health threat, responsible for up to 2.3 million outpatient visits and 250,000 hospitalizations in the U.S. last year alone," said Stéphane Bancel, Chief Executive Officer of Moderna. "Our updated COVID-19 vaccines help protect those at high risk of severe disease, and we are proud to help ensure Americans have access to the latest protection against currently circulating SARS-CoV-2 strains this respiratory virus season."

The updated vaccine composition is based on guidance from the U.S. FDA, which states that COVID-19 vaccines should be developed with a monovalent JN.1 lineage XFG subvariant composition. Following the U.S. FDA's decision, Moderna's updated vaccines are expected to be available in the coming days.

The 2026-2027 formula for Spikevax has already been granted approval by regulators in Europe, South Korea, Singapore, Switzerland, the United Kingdom and other countries. The 2026-2027 formula for mNEXSPIKE has also been granted approval by regulators in Japan. Additional regulatory applications are under review around the world in preparation for the coming season.

You or your child should not get mNEXSPIKE or SPIKEVAX if you had a severe allergic reaction after a previous dose of either mNEXSPIKE, SPIKEVAX, any Moderna COVID-19 vaccine, or to any ingredient in these vaccines.

What are the risks of mNEXSPIKE and SPIKEVAX?

There is a very small chance that mNEXSPIKE or SPIKEVAX could cause a severe allergic reaction. A severe allergic reaction would usually occur within a few minutes to 1 hour after getting a dose of mNEXSPIKE or SPIKEVAX.

• Dizziness and weakness

Myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining outside the heart) have occurred in some people who have received mRNA COVID-19 vaccines. Myocarditis and pericarditis following mRNA COVID-19 vaccines have occurred most commonly in males 12 years through 24 years of age. You should seek medical attention right away if you or your child has any of the following symptoms after receiving mNEXSPIKE or SPIKEVAX, particularly during the 2 weeks after receiving a dose of the vaccine: chest pain, shortness of breath, feelings of having a fast-beating, fluttering, or pounding heart. Additional symptoms in children may include fainting, irritability, poor feeding, lack of energy, vomiting, pain in the abdomen, or cool, pale skin.

Side effects that have been reported in clinical trials with mNEXSPIKE include:

• Injection site reactions: pain, tenderness and swelling of the lymph nodes in the same arm of the injection, swelling (hardness), and redness.

• General side effects: fatigue, headache, muscle pain, joint pain, chills, nausea, vomiting, and fever

Side effects that have been reported in clinical trials with SPIKEVAX include:

• Injection site reactions: pain, tenderness and swelling of the lymph nodes in the same arm of the injection or in the groin, swelling (hardness), and redness

• General side effects: fatigue, headache, muscle pain, joint pain, chills, nausea and vomiting, fever, rash, irritability/crying, sleepiness, and loss of appetite.

• Fainting and febrile seizures (convulsions during a fever) have also been reported

Tell your vaccination provider about all of your or your child's medical conditions, including if you or your child:

• have any allergies

• had a severe allergic reaction after receiving a previous dose of any COVID-19 vaccine

• have had myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the lining outside the heart)
