I don't personally know any people like this. Myself, I was so itchy to get vaccinated I was in line for the soft rollout, i.e. before the program officially started.
Here's my projection: I think there are going to be foot draggers, lazies, doubters, foolish nay sayers. It just doesn't seem a thrill to people to get in line to roll up their sleeve and have a stranger poke in a needle and then experience unknown side effects. They don't think that, it's just the whole gestalt. What's going to happen is these people will start to realize that they are being left behind. Vaccination certification is going to be something they wish they had... vaccination envy is going to be a thing. Universities right now are beginning to stipulate that if you want to get back on campus, you have to certify you've been vaccinated. I think it's going to be a thing with travel, possibly with getting into sporting events, entertainment, possibly your work place, maybe even restaurants. I hope the government doesn't get in the way of this. We'll see.
I've seen a few good ads on TV. Popular media people of all sorts, iconic figures, are going to be in TV spots. People don't want to be left behind and if it becomes apparent that not being vaccinated is a downer, people will get their appointments. Some 5,000,000 people in the USA right now are late in getting their 2nd shots. That's not a big deal, they have a lot of protection, but it's not good.
If they had it in January I'd say odds at at least 80% they'll test negative now. There's only one way to find out, get tested. Another thing they can do is GET VACCINATED. 2 weeks after that they'll be certifiably vaccinated and good as gold.
