The Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices is set to meet to discuss clinical recommendations on the updated vaccine's recipients, including considerations for vulnerable groups like the immunocompromised and elderly.

While the FDA approved the updated vaccines from Moderna and Pfizer, they will not be available immediately to Americans. A CDC advisory panel is scheduled to meet to decide on the use of the vaccines.

Once the CDC director gives a nod to any recommendations, vaccination distribution can start across various sites.

Shares of Novavax Inc NVAX, a company also in the race to update its COVID-19 vaccine, fell almost 13% after the approval of Pfizer's and Moderna's vaccines. Novavax's vaccine, which uses protein-based technology, is still awaiting FDA approval.
