GAITHERSBURG, Md. and PUNE, India, Jan. 10, 2022 /PRNewswire/ — Novavax, Inc. (Nasdaq: NVAX), a biotechnology company dedicated to developing and commercializing next-generation vaccines for serious infectious diseases, and Serum Institute of India Pvt. Ltd. (SII), the world’s largest vaccine manufacturer by volume, today announced a regulatory submission to the South African Health Products Regulatory Agency (SAHPRA) for emergency use authorization (EUA) of Novavax’ recombinant nanoparticle protein-based COVID-19 vaccine candidate with Matrix-M™ adjuvant. If authorized, the vaccine (known as NVX-CoV2373) will be manufactured by and commercialized by SII in South Africa under the brand name Covovax™.
“Novavax’ is thankful for our long-standing history of partnership in South Africa to advance much-needed vaccines. This is exemplified by the country’s vital role in the Phase 2b clinical trial and booster study of our protein-based COVID-19 vaccine,” said Stanley C. Erck, President and Chief Executive Officer, Novavax. “Novavax and Serum Institute remain focused on delivering the COVID-19 vaccine – built on well-understood technology – where it is needed most. We look forward to SAHPRA’s review and, if authorized, delivering the vaccine to help South Africa control the pandemic.”
The submission for the regulatory evaluation by SAHPRA of NVX-CoV2373 includes data from two pivotal Phase 3 clinical trials: PREVENT-19, which enrolled approximately 30,000 participants in the U.S. and Mexico and was published in the New England Journal of Medicine (NEJM); and a trial with almost 15,000 participants in the U.K. which was also published in NEJM. In both trials, the vaccine demonstrated high efficacy with a reassuring safety profile. Serious and severe adverse events were low in number and balanced between vaccine and placebo groups. The most common adverse reactions observed during clinical studies (frequency category of very common ≥1/10) were headache, nausea or vomiting, myalgia, arthralgia, injection site tenderness/pain, fatigue, and malaise. Novavax will continue to collect and analyze real-world data, including the monitoring of safety and the evaluation of variants, as the vaccine is distributed.
In total, Novavax’ vaccine has received authorizations of the vaccine in over 170 countries, including conditional marketing authorization for its vaccine in the European Union and emergency use listing (EUL) from the World Health Organization (WHO). The Novavax/SII vaccine (Covovax) recently received EUA in India, Indonesia and the Philippines, as well as WHO EUL is also currently under review by multiple regulatory agencies worldwide. This includes the submission of its complete chemistry, manufacturing and controls (CMC) data package to the U.S. Food and Drug Administration (FDA) at the end of 2021. The company expects to submit a request for EUA for the vaccine in the U.S. after one month in accordance with guidance from the FDA regarding submission of all EUA vaccines.

Important Safety Information
- NVX-CoV2373 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. A second dose of the vaccine should not be given to those who have experienced anaphylaxis to the first dose of NVX-CoV2373.
- 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.
- NVX-CoV2373 should be given with caution in individuals receiving anticoagulant therapy or those with thrombocytopenia or any coagulation disorder (such as hemophilia) because bleeding or bruising may occur following an intramuscular administration in these individuals.
- The efficacy of NVX-CoV2373 may be lower in immunosuppressed individuals.
- Administration of NVX-CoV2373 in pregnancy should only be considered when the potential benefits outweigh any potential risks for the mother and fetus.
- The effects with NVX-CoV2373 may temporarily affect the ability to drive or use machines.
- Individuals may not be fully protected until 7 days after their second dose. As with all vaccines, vaccination with NVX-CoV2373 may not protect all vaccine recipients.
- The most common adverse reactions observed during clinical studies (frequency category of very common ≥1/10) were headache, nausea or vomiting, myalgia, arthralgia, injection site tenderness/pain, fatigue, and malaise.
