The Novavax vaccine is 90.4 per cent effective at preventing COVID-19 infection, according to the company's phase 3 trial. Novavax gave at least one dose of the vaccine to nearly 20,000 people, with about 10,000 receiving a placebo (sugar pill). Over three months, 14 vaccinated participants tested positive to COVID-19 and 77 placebo participants tested positive. Ten moderate and four severe cases occurred, all in the placebo group. Of the COVID-19 cases that were sequenced, four in five were a variant of interest or variant of concern.
