Trump jumps gun on FDA, says Moderna vaccine 'approved'
The Food and Drug Administration is expected to issue formal approval Friday. This would make Moderna's vaccine the second to be approved in a Western country following the one developed by Pfizer-BioNTech.
Pence indicated that formal approval for Moderna would be a matter of hours.
"We have one, perhaps within hours two, safe and effective coronavirus vaccines," he said.
Thursday's hearing came as the number of deaths from the coronavirus quickly approaches 310,000 in the country with the world's biggest Covid-19 outbreak, which this week began vaccinating health care workers and long-term care residents with the Pfizer vaccine.
Both of the frontrunner vaccines are based on cutting-edge mRNA (messenger ribonucleic acid) technology, which had never been approved prior to the pandemic, and both are two-dose regimens.
