According to a U.S. report published on Friday, the majority of the 43 COVID-19 cases caused by the Omicron variant identified in the United States so far were in people who were fully vaccinated, and one-third of them had received a booster dose.
According to Reuters, the Centers for Disease Control and Prevention (CDC) in the United States reported that 34 of the 43 cases attributed to the Omicron variant had been fully vaccinated. Fourteen of them had also received a booster shot, though five of those cases occurred within 14 days of the additional shot before full protection kicked in.
