Is someone somewhere doing something they haven't been given permission to do?
The states ability to keep track of vaccines administered and to whom, seems not so great to begin with (this would also be a problem for vaccine passports), and if vaccines are expiring and being thrown out anyway because unvaxed people are refusing them, why not I guess, except there's not really much evidence a 3rd shot is needed with mRNA at least. But ... but ... they shold be going to other countries. Yes, but that's beyond the ability of anyone getting a first or a 3rd vaccine to influence. Anymore than eating my broccoli is going to save the starving children.
