The Food and Drug Administration will review pharmaceutical company Moderna’s application for a flu vaccine made with mRNA technology after all.

The Trump administration previously refused to review the company’s application for a new flu vaccine, claiming last week that Moderna had failed to present an “adequate and well-controlled” study.

But the agency has reversed course, Moderna announced Wednesday.
