Since the drug is out there, why don’t they just let people who want it get it for themselves?
Once they institute the vaccination as an optional policy (no vaccination choice allowed), very soon it will morph into a standard policy with the onus to opt out on the shoulders of the dissenters. After that, it will go the way of most bureaucratic operations, i.e., the pressure will be brought to bear on the non-conformists. Soon after, it will be uniform compliance without exception.
In the long run, I dont really think they want to prevent you from getting cancer? If the doctor gave you a pill to make you healthy, you would never come back.
