> Fauci indicated that he based his shifting statements on public polling on the popularity of coronavirus vaccines.
> "When polls said only about half of all Americans would take a vaccine, I was saying herd immunity would take 70 to 75 percent," Fauci said. "Then, when newer surveys said 60 percent or more would take it, I thought, 'I can nudge this up a bit,' so I went to 80, 85."
> He continued: "We really don’t know what the real number is. I think the real range is somewhere between 70 to 90 percent. But, I’m not going to say 90 percent."

Edit: Do we have enough doses even today to vaccinate everyone, worldwide? I think we do not.
As to goalposts, the goalposts moved themselves. If everybody vaccinated when they had a chance there would not be any talk of goalposts.
Instead we will have more millions of people die because couple people died of vaccine and everybody else does not understand law of large numbers.
