The big picture: As of late April, 43% of respondents said they'd already gotten a shot and another 12% said they plan to go to get one the first day they're able to. 10% said they'll get the vaccine whenever they get around to it, and 21% said they will wait awhile and see before getting the vaccine. 14% of respondents said they won't get a vaccine — virtually unchanged since January. In the real world, about 56% of U.S. adults had received at least one shot as of Saturday, per the CDC, suggesting that we're getting very close to the end of the "vaccine eager" population.
