The pace of vaccinations in the United States may be slowing down as vaccine hesitancy takes hold. About 1.8 million vaccination jabs were reported Tuesday, the lowest one-day number in two weeks. Some of the decline could be attributed to availability, dinged by a pause in Johnson & Johnson doses. But demand has softened at some vaccinations sites, even as vaccine availability has been opened up to every U.S. adult. About 1 in 4 Americans say they might decline vaccination. Public health officials and other advocates are countering with new ways to get arms under needles. DC Marijuana Justice promoted a "Joints for Jabs" program. Krispy Kreme offered doughnuts, Budweiser offered beers.
