Introducing mNEXSPIKE: Moderna’s New COVID-19 Vaccine

I am proud to share that mNEXSPIKE®, our new COVID-19 vaccine, is now approved in the U.S., marking Moderna’s third approved product and fifth vaccine program to achieve positive Phase 3 results.

This timely approval will allow for the use of mNEXSPIKE in all adults 65 and older, as well as individuals aged 12-64 with one or more underlying conditions that puts them at high risk for severe outcomes from COVID-19. We are proud of our platform’s continued positive impact on human health, and our relentless commitment to excellence.

Stephen Hoge, our President, sat down to discuss the importance of today’s approval.

We Obsess Over Innovation

As pioneers in mRNA technology, the Moderna team feels a strong responsibility to obsess over innovation, tirelessly working to improve the science behind our products to reduce disease burden and ultimately advance public health. Since the beginning, we’ve rejected the idea of complacency as there’s always another advancement to pursue.

mNEXSPIKE is a prime example of that pursuit. Our vaccine innovation in COVID-19 didn’t stop after the invention of our mRNA-1273 vaccine early in January 2020. Instead, we continued to iterate on its design. With the benefit of years of real-world data and a deeper understanding of the virus, we explored if alternative vaccine design strategies could be more effective. mNEXSPIKE was born from this continued push for excellence. Its streamlined vaccine design aims to target key parts of the spike protein rather than the entire spike protein, and at a lower dose.

The Ongoing Burden of COVID-19

COVID-19 remains a significant public health threat. Over 47,000 Americans died from COVID-19 in 2024 – about one death every 11 minutes. Older adults face disproportionately higher risks of severe illness, hospitalization and death – adults aged 65 and older account for two-thirds of COVID-19 related hospitalizations and 80% of all adults hospitalized with COVID-19 who died in hospitals were 65 years or older. Many older adults have multiple comorbidities including obesity (1.4x risk), diabetes (1.8x risk), and chronic lung disease (3.2x risk) that can further amplify vulnerability.

mNEXSPIKE has the potential to be a critical tool as we aim to reduce the burden of disease.

Delivering on the Promise of mRNA

The flexibility and adaptability of our mRNA platform allows for constant innovation – complacency is not an option. We are looking forward to many more upcoming moments when we will continue to show the promise of mRNA–with several Phase 3 readouts approaching and continued momentum in our priority programs across respiratory, latent, oncology and rare disease. Our commitment to patients and advancing mRNA medicine has never been stronger.

INDICATION

mNEXSPIKE is a vaccine to protect against COVID-19. mNEXSPIKE is for people who have received a COVID-19 vaccine before and are:

  • 65 years of age and older, or

  • 12 years through 64 years of age at high risk for severe COVID-19.

Vaccination with mNEXSPIKE may not protect all people who receive the vaccine.



IMPORTANT SAFETY INFORMATION

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

What are the risks of mNEXSPIKE?

There is a very small chance that mNEXSPIKE 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. For this reason, your healthcare provider may ask you to stay for a short time at the place where you received your vaccine. Signs of a severe allergic reaction can include:

  • Trouble breathing

  • Swelling of your face and throat

  • A fast heartbeat

  • A rash all over your body

  • 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 the vaccine, 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

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

Tell your vaccination provider about all of your medical conditions, including if you:

  • 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)

  • have a fever

  • have a bleeding disorder or are on a blood thinner

  • are immunocompromised or are on a medicine that affects your immune system

  • are pregnant or plan to become pregnant

  • are breastfeeding

  • have received any other COVID-19 vaccine

  • have ever fainted in association with an injection

These may not be all the possible side effects of mNEXSPIKE. Ask your healthcare provider about any side effects that concern you. You may report side effects to Vaccine Adverse Event Reporting System (VAERS) at1-800-822-7967 or http://vaers.hhs.gov.
