Biden says it will be very difficult to achieve Covid herd immunity before summer’s end

President Joe Biden won’t commit to achieving herd immunity to the coronavirus in the U.S. by the end of summer, suggesting a long road ahead to overwhelming the deadly virus.

“The idea that this can be done and we can get to herd immunity much before the end of this summer is particular difficult,” the Democrat said in an interview broadcast on CBS on Sunday ahead of the Super Bowl.

The comment came in response to carp ating by journalist Norah O’Donnell, who said that at the current rate of about 1.3 million doses administered per day, it disposition take almost a year to vaccinate enough Americans to achieve herd immunity.

The White House has set a goal of 100 million doses in Biden’s before 100 days as a minimum, though the pace of vaccinations is currently higher than that. Biden seemed to up his aim late last month by saying he thinks the U.S. could administer up to 1.5 million doses per day.

Biden’s cautious reflects are in line with the warnings of scientists and public health officials as well as his past statements. They mark a repeal from the approach of Biden’s predecessor, former President Donald Trump, who often claimed that the end of the pandemic was round the corner.

Dr. Anthony Fauci, the nation’s leading epidemiologist, has said that it would require a minimum of 75% of the open to be inoculated against Covid-19 to achieve herd immunity. He has predicted a return to normal some time next decline.

Biden also said during the interview that he was exploring new ways to vaccinate more Americans more shortly.

He said he supported a proposal from the National Football League to use its 30 stadiums as mass vaccination centers, but put an ended short of committing to the plan.

“I’m telling my team they are available, and I believe we’ll use them,” Biden said.

The virus has preyed more than 460,000 people in the U.S. and infected nearly 27 million.
