FWIW, I think there are more people in the "meh, maybe" category than in the ardent anti category.
For example, I teach IT classes at a junior college. I had a student whose parents are on very different sides of the fence and have given him very mixed messages about the vaccine. My student had kinda waffled back and forth on it, thinking that he might get it at some point, but not really taking any action.
Today, we partnered with a local pharmacy to have a vaccine clinic on-site during class hours. Guess what? He got vaccinated.
I think as the convenience factor increases -- like with Walmart announcing people can walk in to any of their pharmacies nationwide without an appointment -- we will see many of those kinds of people start to get vaccinated.
I don't think the situation is as dire as some think it is.
