No cases of severe COVID-19 occurred among participants who received the vaccine, known as mRNA-1273, and there were no safety concerns.
The US Food and Drug Administration on December 18 issued an emergency use authorization for the vaccine, a lipid-nanoparticle-encapsulated mRNA vaccine expressing the prefusion-stabilized spike glycoprotein.
The trial began in July and enrolled 30,420 adults in the United States. Volunteers were randomly assigned in a 1:1 ratio to receive either two doses of the vaccine or two shots of saline placebo 28 days apart. The average age of the participants was 51 years.
