Genuine question:
For those who favor these sorts of mandates, is it based on the belief that the vaccines prevent infection, and people who don't get them are therefore a danger to others because they're much more likely to infect others with covid? Or is it enough that vaccines reduce a vaccinated person's risk of death, so people should be required to do it for their own good regardless of whether anyone else is affected?
Your points aren't subjective beliefs, it's a fact that if you are vaccinated you are less likely to catch Covid, less likely to pass it on, and less likely to get ill with it if you do get it.
I am in favour of mandates for certain jobs, certainly. Jobs where someone's personal choice not to protect themselves might have a knock on negative effect on others. The moral question is where do my rights (not to have) end and my responsibilities (to those I come into contact with) begin.
Yes, (obviously) the vaccine isn't perfect, and yes, protection wanes over time. The people accusing science of having lied and gaslighted them into thinking otherwise are simply showing their own lack of knowledge about how this type of vaccine (and others) work.
The article in any case is all hypothetical, as others have said.
Might it happen? Sure.
Is it a certainty? No.
Will the majority of people at whatever age take up the booster? Yes
