“I’ve done some of that; I’m going to try to stop and listen, in fact, to what people’s specific questions are,” NIH Director Francis Collins said Sunday on NBC’s “Meet the Press.” An NBC News poll released Sunday showed that 82% of Democrats had already been vaccinated or plan to be as soon as possible, against 45% of Republicans. Almost one-quarter of Republicans said they won’t get vaccinated and another 10% said they’ll do so only if required. That hesitancy has been seen as a roadblock to the U.S. achieving herd immunity against Covid 19. “We’re all in this together. And clearly, if we’re going to be able to put Covid-19 behind us, we need to have all Americans take part in getting us to that point,” Collins said.
