The US Food and Drug Administration has discussed with vaccine-maker Novavax the need for an additional trial of its Covid-19 vaccine as a post-approval commitment, a source familiar with the matter told CNN.

Federal regulators have asked Novavax to complete an additional clinical trial on its COVID-19 vaccine after previously delaying approval, the Wall Street Journal reported on Friday, citing people familiar with the matter.

Novavax has been available since 2022 through a pandemic-era Emergency Use Authorization. A decision on full approval – which rival mRNA shots from Moderna and Pfizer and its partner BioNTech already have - was due from the Food and Drug Administration by April 1, but had been delayed by the FDA without explanation.
