Dr. Anthony Fauci on Sunday defended raising the bar on his projections about herd immunity for COVID-19 — insisting that he’s only been offering “estimates” all along.

“We have to realize that we have to be humble and realize what we don’t know. These are pure estimates,” Fauci told CNN anchor Dana Bash on “State of the Union.”…

But asked Sunday why he “wasn’t straight with the American public to begin with,” Fauci denied that he had been sugarcoating his predictions.

“No actually, Dana, I don’t think it can be interpreted as being straight or not,” the director of the National Institute of Allergy and Infectious Diseases said.
