On June 30, 2022, local media reported that SSI was seeking approval to export millions of versions of the Novavax vaccine Covovax to the United States in July 2022 under the Nuvaxovid ™ brand name.

As of July 2, 2022, Nuvaxovid has been approved for adult use in more than 40 countries. Recently, the Taiwan Food and Drug Administration has granted Nuvaxovid an EUA.

Nuvaxovid (NVX-CoV2373) is a protein-based vaccine designed from the gene sequence of the first strain of SARS-CoV-2 beta coronavirus.

This Novavax vaccine integrates a patented saponin-based Matrix-M adjuvant. It has a powerful and well-tolerated effect by stimulating the invasion of antigen-presenting cells into the injection site, enhancing antigen presentation in local lymph nodes, and promoting an immune response. Helps immunized people make antibodies against the virus.

In July 2020, Novavax was awarded $ 1.6 billion by the US Federal Government to complete late-stage clinical development and provide 100 million doses of the NVX-CoV2373 vaccine.
