The Food and Drug Administration has authorized Moderna’ Covid-19 vaccine for emergency use, according to a statement posted on the agency’s website Friday.
The experimental vaccine is the second shot to get an emergency authorization in the U.S after the FDA cleared Pfizer and its partner BioNTech’s vaccine last week.
Moderna’s shot, which uses a similar new messenger-RNA technology as Pfizer-BioNTech’s, is 94.1% effective at preventing symptomatic Covid-19, the FDA’s staff said in a report on Tuesday.
