Not just US. Everywhere got people that wont take a vaccine. However you dont need everyone to be vaccinated for covid to disappear. And look at it this way, they already have a headstart as more than 9 million (actual some estimate to be around 20 million) that have already been infected. These people can take one or dont and they will likely be less infectious already.
The vaccine is around USD20 per shot. Well within US or any developed country's budget. Spending money on manufacturing and logistics will fire up their economy as well.
They already announce stuffs like , if you get one today, it is free, if you want one X months later, it will be $1000. Will you take one?
