Novavax Secures FDA Approval for COVID-19 Vaccine Amid Controversy

The US FDA has approved Novavax's protein-based COVID-19 vaccine, Nuvaxovid, for adults aged 65 and older, as well as individuals between 12 and 64 with underlying health conditions. The vaccine has been available under emergency use authorization since July 2022. Novavax had initially sought approval for a broader population, but the FDA's decision restricts the vaccine's use. The company remains confident in its shot's ability to play a role in the endemic market, citing market research and CDC statistics indicating that older individuals and those with underlying conditions are most likely to seek vaccination.
