“让我们说清楚: the day we got here, 4000 people a day were dying and one percent of Americans were vaccinated. 今天, deaths are down 75 百分, and almost 200 million Americans are fully vax’ed,” 他 说过 in a tweet. “We still have a LOT of work to do.”
“But if anyone wants to have a debate about COVID, bring it on,” Klain added.
According to Biden, he is taking advice on how to deal with the omicron variant from 博士. 安东尼·福西 and the Centers for Disease Control and Prevention (CDC), which recommended the newly established travel restrictions.
