On Oct. 3, 2023, Novavax announced that it’s COVID-19 Vaccine, Adjuvanted (2023-2024 Formula) (NVX-CoV2601) had received Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) for active immunization to prevent COVID-19 in individuals aged 12 and older. Immediately upon authorization, Novavax’s vaccine had also been included in the recommendations issued by the U.S. Centers for Disease Control and Prevention (CDC) on September 12, 2023.

Doses will be available nationwide at thousands of locations, including national and local retail pharmacies and physicians’ offices, following the Center for Biologics Evaluation and Research release of vaccine batches, expected in the coming days.

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

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, injection site pain, fatigue and malaise.

The EUA aligns with globally harmonized guidance from the FDA, European Medicines Agency and the World Health Organization to target the XBB strain this fall. Novavax is working with these and other global regulatory authorities on authorizations for its vaccine.
