Novavax COVID-19 Vaccine Nuvaxovid™ Provisionally Registered in Australia as a Booster in Individuals Aged 18 and Over

Novavax, Inc. (NASDAQ: NVAX), a biotechnology company dedicated to developing and commercializing next-generation vaccines for serious infectious diseases, today announced that the Australian Therapeutic Goods Administration (TGA) has granted provisional registration of Nuvaxovid™ (NVX-CoV2373) COVID-19 vaccine as a booster in individuals aged 18 and over.

“Today’s provisional registration for Nuvaxovid as a booster in Australia is an important step in ensuring broad global access to diversified vaccine options,” said Stanley C. Erck, President and Chief Executive Officer, Novavax. “As COVID-19 continues to persist and evolve, we are pleased to be able to offer the first protein-based COVID-19 vaccine registered for use as both a primary series and now booster regardless of previous vaccine history.”

The provisional registration was based on data from Novavax’ Phase 2 trial conducted in Australia, from a separate Phase 2 trial conducted in South Africa, and from the UK-sponsored COV-BOOST trial. As part of the Phase 2 trials, a single booster dose of Nuvaxovid was administered to healthy adult participants approximately six months after their primary two-dose vaccination series of Nuvaxovid. The third dose produced increased immune responses comparable to or exceeding levels associated with protection in Phase 3 clinical trials. In the COV-BOOST trial, Nuvaxovid induced a robust antibody response when used as a heterologous third booster dose.

In the Novavax-sponsored trials, following the booster, local and systemic reactions were generally short-lived with a median duration of approximately two days. The incidence of Grade 3 or higher events remained relatively low. Safety reporting of reactogenicity events showed an increasing incidence across all three doses of Nuvaxovid, reflecting the increased immunogenicity seen with a third dose. Medically attended adverse events, potentially immune-mediated medical conditions, and severe adverse events occurred infrequently following the booster dose and were balanced between vaccine and placebo groups.

The TGA granted provisional registration in January 2022 for use of Nuvaxovid in individuals aged 18 and over. Novavax filed for expanded provisional registration in Australia for use in adolescents aged 12 through 17 in May 2022.

Novavax’ sponsor in Australia is Biocelect Pty. Ltd.

Authorization in the U.S.
The Novavax COVID-19 vaccine (NVX-CoV2373) has not yet been authorized for use in the U.S. and the trade name Nuvaxovid™ has not yet been approved by the U.S. Food and Drug Administration.

Important Safety Information

  • Nuvaxovid is contraindicated in persons who have a hypersensitivity to the active substance, or to any of the excipients.
  • Events of anaphylaxis have been reported with administration of COVID-19 vaccines. Appropriate medical treatment and supervision should be available in case of an anaphylactic reaction following the administration of the vaccine. Close observation for at least 15 minutes is recommended and a second dose of the vaccine should not be given to those who have experienced anaphylaxis to the first dose of Nuvaxovid.
  • Anxiety-related reactions, including vasovagal reactions (syncope), hyperventilation, or stress‐related reactions may occur in association with vaccination as a psychogenic response to the needle injection. It is important that precautions are in place to avoid injury from fainting.
  • Vaccination should be postponed in individuals suffering from an acute severe febrile illness or acute infection. The presence of a minor infection and/or low-grade fever should not delay vaccination.
  • Nuvaxovid should be given with caution in individuals receiving anticoagulant therapy or those with thrombocytopenia or any coagulation disorder (such as haemophilia) because bleeding or bruising may occur following an intramuscular administration in these individuals.
  • The efficacy of Nuvaxovid may be lower in immunosuppressed individuals.
  • Administration of Nuvaxovid in pregnancy should only be considered when the potential benefits outweigh any potential risks for the mother and foetus.
  • The effects with Nuvaxovid may temporarily affect the ability to drive or use machines.
  • Individuals may not be fully protected until seven days after their second dose. As with all vaccines, vaccination with Nuvaxovid may not protect all vaccine recipients.
  • The most common adverse reactions observed during clinical studies were headache, nausea or vomiting, myalgia, arthralgia, injection site tenderness/pain, fatigue, and malaise.
