"Right now, there are thousands of people saying, ‘See, I told you so'"

“This is devastating,” said Frank Luntz, a longtime GOP pollster who has been working to win over vaccine-hesitant Republicans. “At the very moment that conservatives were starting to reconsider their hesitancy, they are told that their fears are real and justified. Right now, there are thousands of people saying, ‘See, I told you so.’ ”... “We’re very concerned that this announcement for very rare side effects could have a disproportionate impact in triggering and bringing fears to the surface,” said Douglas Kriner, a government professor at Cornell University who has studied vaccine hesitancy. Kriner said survey respondents had raised questions about coronavirus vaccines that ranged from understandable to improbable. “Four percent of people volunteered in an open-ended question that death was a common side effect” of getting vaccinated, Kriner said.
