The Food and Drug Administration on Wednesday authorized use of Pfizer's Paxlovid, a series of pills, taken at home that prevent nearly 90% of severe COVID-19 among those at high risk. On Thursday, the FDA authorized use of a second antiviral, molnupiravir, which appears to prevent progression to severe disease about 30% of the time.
