Novavax, Inc. is a US vaccine development company headquartered in Gaithersburg, Maryland, with additional facilities in Rockville, Maryland and Uppsala, Sweden. In 2020, the company will undergo Phase III clinical testing of adults for its candidate vaccines for seasonal flu, NanoFlu and candidate vaccines for COVID-19 prevention.

Coronavirus: what we know about the Novavax vaccine

On March 11, 2021, Novavax reported that its COVID-19 vaccine is 96% efficacious in reducing mild, moderate or severe disease. The Maryland-based company joins the handful of manufacturers that have reported encouraging data on a COVID-19 vaccine; three, Pfizer-BioNTech, Moderna and Johnson & Johnson’s Janssen Pharmaceuticals, have already received emergency use authorization for their shots from the U.S. Food and Drug Administration.

Before that, on Thursday, January, 28, 2021, the Novavax’s company CEO Stanley Erck, said that their vaccine would be 89.3% effective, according to clinical trials conducted by the American biotechnology company Novavax. “NVX-CoV2373 has the potential to play an important role in solving this global public health crisis”.

In detail, its effectiveness was estimated at 95.6% against the initial strain and at 85.6% against the British variant. The only downside is that it is less for the South African mutation (49.4%). The company said it is immediately embarking on the development of a new vaccine targeting this variant.

How does the Novavax vaccine work? Unlike the vaccines from Pfizer and Moderna, which use messenger RNA technology, biotech has developed a so-called “subunit” recombinant version, which also requires two injections 3 weeks apart. The virus has spikes (viral proteins) on its surface to come into contact with the cells to be infected. The injection of the Novavax vaccine thus comprises fragments of the coronavirus which make it possible to provoke an immune response in the human body.
