The percentage of Americans willing to take a Covid-19 vaccine appears to be falling – and if only half of the country is willing to get vaccinated, Covid-19 could stick around for years, Dr. Francis Collins, director of the National Institutes of Health, warned on Friday.
"When I look at the attitudes that are out there now about this vaccine and about who would be interested in taking it – it's really, really troubling," Collins said, speaking at a National Press Club in a virtual event.
"I've been talking so optimistically about how we are likely to have a vaccine by the end of the year, but if only 50% of Americans are interested in taking it, we're never going to get to that point of immunity across the population where Covid-19 goes away. It could be here for years," Collins said.
Only 51% of Americans said they would try to get a Covid-19 vaccine once one is widely available at a low cost, according to a CNN poll conducted by SSRS earlier this month, and that percentage has dropped since May.
