This is also the fourth vaccine the United States has added to its arsenal. Novavax Inc said that the jabs are 90% effective at preventing symptomatic Covid-19 and showed 100% effectiveness at preventing moderate and severe symptoms.
The vaccine showed 93% effectiveness against variants of concern based on test results from a secondary analysis which mostly consisted of cases of the alpha variant which is predominant in the United States.
