STATEMENT: Novavax's updated COVID-19 vaccine is now approved in the EU (2)

GAITHERSBURG, Md., Nov. 1, 2023 /PRNewswire/ -- Novavax, Inc. (Nasdaq: NVAX), a global company developing protein-based vaccines with its Matrix-M™ adjuvant, today announced that the European Commission has granted approval of COVID-19 vaccine (recombinant, adjuvanted) (NVX-CoV2601) Nuvaxovid™ XBB.1.5 injectable dispersion for active immunization to prevent COVID-19 caused by SARS-CoV-2 in people 12 years or older. This decision follows the positive opinion for approval from the Committee for Medicinal Products for Human Use of the European Medicines Agency.

"Today's approval of the only updated non-mRNA protein-based COVID-19 vaccine in the EU is an important milestone as the need for vaccination continues," said John C. Jacobs, President and CEO of Novavax. "Novavax is working closely with national authorities to have our updated vaccine delivered and available in Europe in the coming weeks."

Novavax is working closely with EU member states that have ordered doses through the advance purchase agreement to confirm the timing of delivery of doses on a country-by-country basis.

The approval was based on non-clinical data showing that Novavax's updated COVID-19 vaccine induced functional immune responses against the XBB.1.5, XBB.1.16 and XBB.2.3 variants. Additional nonclinical data demonstrated that the Novavax vaccine induced neutralizing antibody responses to emerging subvariants BA.2.86, EG.5.1 FL.1.5.1, and XBB.1.16.6, as well as multifunctional cellular (T cell) CD4 responses against EG. . 5.1 and XBB.1.16.6. These data indicate that the Novavax vaccine can stimulate both arms of the immune system and can induce a broad response against circulating variants.1,2

In clinical trials, the most common adverse reactions associated with Novavax's prototype COVID-19 vaccine (NVX-CoV2373) included headache, nausea or vomiting, muscle pain, joint pain, injection site tenderness , pain at the injection site, fatigue and discomfort.

Novavax's vaccine is authorized for use in the US and is currently under review in other markets.

About Nuvaxovid™ XBB Injectable Dispersion attack the Omicron XBB.1.5 subvariant. It is a protein-based vaccine made by creating copies of the spike surface protein of SARS-CoV-2 that causes COVID. Using Novavax's unique recombinant nanoparticle technology, the non-infectious spike protein serves as an antigen that primes the immune system to recognize the virus, while Novavax's Matrix-M™ adjuvant enhances and amplifies the immune response. The vaccine is presented in a ready-to-use liquid formulation and is stored at a temperature between 2º and 8º C, allowing existing vaccine supply channels and the cold chain to be used.

About Matrix-M™ Adjuvant When added to vaccines, Novavax's patented saponin-based Matrix-M adjuvant enhances the immune system's response, making it broader and longer-lasting. Matrix-M adjuvant stimulates the entry of antigen-presenting cells at the injection site and enhances antigen presentation to local lymph nodes.
