The authorization would set the stage to further widen the U.S. booster campaign after earlier authorization of the Pfizer Inc.-BioNTech SE shot.
About 170 million fully vaccinated people in the U.S. received the Moderna or Pfizer shots, or 92% of the total inoculated so far.

105-year-old woman who survived 1918 flu, World War II dies from COVID-19
She lived a life of adventure that spanned two continents. She fell in love with a World War II fighter pilot, barely escaped Europe ahead of Benito Mussolini's fascists, ground steel for the U.S. war effort and advocated for her disabled daughter in a far less enlightened time. She was, her daughter said, someone who didn't make a habit of giving up.
And then this month, at age 105, Primetta Giacopini's life ended the way it began - in a pandemic.
Proposed bill would require COVID vaccine, negative test for domestic air travel ahead of holidays

Long haul COVID symptoms affect 1/3 of survivors, University of Oxford study finds
large study, involving more than 270,000 patients in the U.S. and the United Kingdom, conducted by the University of Oxford found 1/3 of all COVID survivors experience at least one symptom three to six months after getting infected.
Doctors at Northwestern Medicine's Comprehensive COVID-19 Center said their long COVID patients experience symptoms even longer.
Because no one knows how long symptoms last, doctors say society must be prepared for the long-term impact on the economy and the health care system. While doctors expect long haulers to improve, for now they continue to deal with what they call a second pandemic.
