(E) The FDA has just approved the Novavax vaccine, which is now the four Covid-19 vaccine in the U.S after Pfizer, Moderna, and J&J.

The vaccine is highly effective, according to the clinical data: two doses were 90% effective at preventing illness from Covid when tested in a study involving about 30,000 adults ages 18 and older.

Following is a short tutorial on Novavx’s recombinant protein technology:
