New York Times reporting: An early study of coronavirus test results in South Africa suggests that, so far, patients infected with the omicron variant may be hospitalized less often than patients infected with earlier versions of the virus. The study — which was released Tuesday and is based on only three weeks of data — also shows that vaccines are not as effective against the variant, which poses a higher risk of breakthrough infections. Booster shots increased the Pfizer vaccine’s efficacy against infection.
