Novavax, Inc. (Nasdaq: NVAX), a global company advancing protein-based vaccines with its novel Matrix-M™ adjuvant, today announced that Nuvaxovid™ (NVX-CoV2373) has been recommended for full Marketing Authorization (MA) for use as a primary series in individuals aged 12 and older and as a booster in individuals aged 18 and older for the prevention of COVID-19 in the European Union (EU) following a positive opinion issued by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency. The European Commission will review the CHMP recommendation and is expected to make a final decision on the MA.
“The positive CHMP Opinion for full Marketing Authorization for our COVID vaccine brings us one step closer to full authorization and will provide an approval pathway for an updated vaccine in time for the fall,” said John C. Jacobs, President and Chief Executive Officer, Novavax.
Novavax has demonstrated the efficacy and safety of Nuvaxovid as a primary series, and the immunogenicity and safety of the vaccine as a booster in individuals aged 12 and older in the Phase 3 PREVENT-19 trial, Phase 2 trials and in real-world evidence.
Novavax’s COVID vaccine is authorized for use in more than 40 markets around the world. In the EU, Nuvaxovid has been conditionally authorized as a two-dose primary series in adults and adolescents, and as a booster dose in adults.

Warnings and Precautions
Management of Acute Allergic Reactions: Appropriate medical treatment to manage immediate allergic reactions must be immediately available in the event an acute anaphylactic reaction occurs following administration of the Novavax COVID-19 Vaccine, Adjuvanted. Monitor the Novavax COVID-19 Vaccine, Adjuvanted recipients for the occurrence of immediate adverse reactions according to the Centers for Disease Control (CDC) and Prevention guidelines.
Myocarditis and Pericarditis: Clinical trials data provide evidence for increased risks of myocarditis and pericarditis following administration of the Novavax COVID-19 Vaccine, Adjuvanted (see Full EUA Prescribing Information). The CDC has published considerations related to myocarditis and pericarditis after vaccination, including for vaccination of individuals with a history of myocarditis or pericarditis (https://www.cdc.gov/vaccines/covid-19/clinical-considerations/interim-considerations-us.html#myocarditis-pericarditis).
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 immunosuppressant therapy, may have a diminished immune response to the Novavax COVID-19 Vaccine, Adjuvanted.
Limitations of Vaccine Effectiveness: The Novavax COVID-19 Vaccine, Adjuvanted may not protect all vaccine recipients.
Adverse reactions reported in clinical trials following administration of the Novavax COVID-19 Vaccine, Adjuvanted include injection site pain/tenderness, fatigue/malaise, muscle pain, headache, joint pain, nausea/vomiting, injection site redness, injection site swelling, fever, chills, injection site pruritus, hypersensitivity reactions, lymphadenopathy-related reactions, myocarditis, and pericarditis.
Myocarditis, pericarditis, anaphylaxis, paresthesia, and hypoesthesia have been reported following administration of the Novavax COVID-19 Vaccine, Adjuvanted outside of clinical trials.
Additional adverse reactions, some of which may be serious, may become apparent with more widespread use of the Novavax COVID-19 Vaccine, Adjuvanted.
Reporting Adverse Events and Vaccine Administration Errors
The vaccination provider enrolled in the federal COVID-19 Vaccination Program is responsible for mandatory reporting of the following to the Vaccine Adverse Event Reporting System (VAERS):
- vaccine administration errors whether or not associated with an adverse event,
- serious adverse events (irrespective of attribution to vaccination),
- cases of myocarditis,
- cases of pericarditis,
- cases of Multisystem Inflammatory Syndrome (MIS), in adults and children, and
- cases of COVID-19 that results in hospitalization or death.
Complete and submit reports to VAERS online: For further assistance with reporting to VAERS, call 1-800-822-7967. The reports should include the words “Novavax COVID-19 Vaccine, Adjuvanted EUA” in the description section of the report.

About Nuvaxovid™ (NVX-CoV2373)
NVX-CoV2373 is a protein-based vaccine made by creating copies of the surface spike protein of SARS-CoV-2 that causes COVID. With Novavax’s unique recombinant nanoparticle technology, the non-infectious spike protein serves as the antigen that primes the immune system to recognize the virus, while Novavax’s Matrix-M adjuvant enhances and broadens the immune response. The vaccine is packaged as a ready-to-use liquid formulation and is stored at 2° to 8°C, enabling the use of existing vaccine supply and cold chain channels.
About the PREVENT-19 Phase 3 Trial
The PRE-fusion protein subunit Vaccine Efficacy Novavax Trial COVID-19 (PREVENT-19) was a randomized, placebo-controlled, observer-blinded Phase 3 trial conducted in the U.S. and Mexico to evaluate the efficacy and safety of NVX-CoV2373 as a primary series and as a booster in adults and adolescents to prevent SARS-CoV-2 infection. As a primary series, the primary endpoint was the first occurrence of polymerase chain reaction (PCR)-confirmed symptomatic (mild, moderate, or severe) COVID-19 with onset at least seven days after the second dose in 29,960 adult participants aged 18 and older at baseline without protocol violations prior to illness. A secondary endpoint was the prevention of PCR-confirmed, symptomatic moderate or severe COVID-19. Full results of the trial were published in the New England Journal of Medicine.
The pediatric expansion of the trial evaluated 2,247 adolescents aged 12 through 17 years in the U.S. Results from the expansion were announced in February 2022. The adult booster expansion of the trial evaluated a single booster dose of the vaccine in adult participants approximately six months after their primary two-dose vaccination series. Results from the expansion were announced in October 2022.
About Matrix-M™ Adjuvant
When added to vaccines, Novavax’s patented saponin-based Matrix-M adjuvant enhances the immune system response, making it stronger, broader, and more durable. The Matrix-M adjuvant stimulates the entry of antigen-presenting cells at the injection site and enhances antigen presentation in local lymph nodes.
