COVID Herd Immunity Point Still Unclear, Biden Says

Steve Herman

   WHITE HOUSE - U.S. President Joe Biden on Tuesday will update the
   country on how it is faring in the battle against COVID-19 and the
   effort to get more Americans vaccinated against the coronavirus.

   The president, following remarks on Monday afternoon at a community
   college in Virginia, was asked by a reporter when the country will
   reach herd immunity -- meaning, when will a sufficient percentage of
   the population be immune to the coronavirus that causes COVID-19
   because of previous exposure or inoculation.

   "There's a debate about what constitutes herd immunity," he said. "Is
   it 70 percent, 68 percent, 81 percent?"

   No matter the precise percentage, Biden said he thinks "by the end of
   the summer, we'll be in a very different position."And what is critical
   now, according to the president, is for everyone to get vaccinated.
