FDA Finds Moderna Vaccine To Be “Highly Effective”

The Wall Street Journal reports:

The Food and Drug Administration said Tuesday that the Covid-19 vaccine developed by Moderna is “highly effective,” suggesting the vaccine could soon be added to the arsenal against the pandemic.

Moderna’s documents posted by the FDA included new data suggesting that its vaccine begins to prevent asymptomatic infections after the first dose.

The ability of a vaccine to prevent asymptomatic infections is important because it could help significantly slow the spread of the coronavirus.
