Can't even give the stuff away now, you guys are hopeless
What is hopeless is how they are rolling the crap out. Anybody who REALLY wanted it now have it. And you have probably 20% of the population who might get it, but are not going to go out of their way. And the longer they don't get it, the more likely they are to say "we are going back to normal- I don't need it."
If Mohamed will not go to the mountain, bring the mountain to Mohamed. Offer it at sporting events. Set up a table at every major air port (these are people who want to fly and get out.) Bring it to the schools, the slaughterhouses and the employers with over 200 employees. No appointment needed- you don't need to even go to a pharmacy.
I suppose if you start doing that, you start to dilute the "exclusivity" of the vaccine. But those who want to feel like they have "done their part" or are the part of society that cares about others and will do their civic duty already have their vaccines in their arms. Now it needs to turn to those who would be willing to get it but are not going to go out of their way.
Oh, and something that I would disagree with, but would encourage others is "peer pressure." At the ball game you would get a conversation like "son, there is no reason for you not to be vaccinated, go over to that nice nurse and get your damn shot." You can introduce effective social pressure without giving the individual the "out" like saying "I will set up an appointment tomorrow, dad.," without following through.
