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.
In all, 196 cases of symptomatic COVID-19 occurred at least 14 days after participants received their second shot 185 cases in the placebo group, and 11 in the vaccine group.

Review concludes universal mask use by lay persons reduces the spread of viral infections including SARS-CoV-2
Findings affirm policy promised by President-Elect Biden, who will ask Americans on Inauguration Day to wear masks for 100 days

Even small reductions in the transmission rate can lead to large reductions in the number of people becoming infected over time.
