mNEXSPIKE was studied in a noninferiority trial:
Relative vaccine efficacy results1
Relative vaccine efficacy against COVID-191*
Per-protocol set for efficacy | mNEXSPIKE (10 µg)n=5679 | Spikevax (50 µg)n=5687 |
|---|---|---|
Number of participants with COVID-19, n (%) | 9.9% (560) | 10.8% (617) |
Incidence rate per 100 person-months | 1.4 | 1.5 |
Relative vaccine efficacy(99.4% CI)† | 9.3% (-6.6, 22.8) | |
mNEXSPIKE satisfied the primary criterion for noninferiority.1
STUDY WAS NOT DESIGNED TO EVALUATE SUPERIORITY.

rVE analyses by subgroups were descriptive without P values.
*Presence of at least one symptom from a list of COVID-19 symptoms and a positive NP swab for SARS-CoV-2 by RT-PCR. Listed symptoms were fever (temperature ≥38°C/≥100.4°F) or chills, cough, shortness of breath or difficulty breathing, fatigue, muscle aches or body aches, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting, and diarrhea.1
†Lower bound of two-sided 99.4% (alpha-adjusted) Cl of rVE >-10% (1-sided alpha spending: 0.0028).1

Indication and Important Safety Information
INDICATION
mNEXSPIKE (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).
mNEXSPIKE is approved for use in individuals who have been previously vaccinated with any COVID-19 vaccine and are:
- 65 years of age and older, or
- 12 years through 64 years of age with at least one underlying condition that puts them at high risk for severe outcomes from COVID-19.
IMPORTANT SAFETY INFORMATION
Contraindications
Do not administer mNEXSPIKE to individuals with a known history of severe allergic reaction (e.g., anaphylaxis) to any component of mNEXSPIKE or to individuals who had a severe allergic reaction following a previous dose of SPIKEVAX (COVID-19 Vaccine, mRNA) or any Moderna COVID-19 vaccine authorized for emergency use.
Warnings and Precautions
- Management of Acute Allergic Reactions: Appropriate medical treatment must be immediately available to manage potential anaphylactic reactions following administration of mNEXSPIKE.
- Myocarditis and Pericarditis: Postmarketing data with authorized or approved mRNA COVID-19 vaccines have demonstrated increased risks of myocarditis and pericarditis, with onset of symptoms typically in the first week following vaccination. The observed risk has been highest in males 12 years 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.
- Altered Immunocompetence: Immunocompromised persons, including individuals receiving immunosuppressive therapy, may have a diminished immune response to mNEXSPIKE.
- Limitations of Vaccine Effectiveness: mNEXSPIKE may not protect all vaccine recipients.
Adverse Reactions
The most commonly reported (≥10%) adverse reactions were pain at the injection site, fatigue, headache, myalgia, chills, arthralgia, axillary swelling or tenderness, and nausea/vomiting.
Reporting Adverse Events and Vaccine Administration Errors
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 or by calling 1-800-822-7967.
