Do you get the flu vaccine every year?
Yes.
And flu is potentially serious for the older and the more vulnerable, which is why it is freely available to them every year, even though (a) humans, even the vulnerable, have a higher degree of natural resistance to flu on account of it usually not being a novel virus and (b) flu is nowhere near as dangerous to people as Covid currently is.
I have very little doubt that at some point in time, what we now know as Covid will probably be no more serious than flu currently is to us. But you need to remember that flu kills thousands every year, and a "very bad flu year" can easily result in 40-50,000 associated deaths in the UK alone. We have to learn to live with it unless it conveniently dies out like Spanish Flu did. But that doesn't mean that right now, at this moment in time, we should be putting the most vulnerable at risk of something with heightened morbidities.
But I do think there is a balance that has to be struck. If your frail and elderly mother lives in a care home, are you absolutely fine with someone working in physical contact with her who is refusing to be vaccinated against a virus that might be asymptomatic in the worker, but could kill your mother?
I am not in favour of forcing people to have a vaccine that they do not want. But there are many examples of occupational requirements that we accept simply because they exist; and right now when we have so many people vulnerable to a virus that is new to us, perhaps we do need to consider that some occupations or types of contact do need to be conducted by vaccinated people. Yes, people should have the free choice to take the vaccine or not. Shouldn't vulnerable people have the same right to make decisions about their lives? And shouldn't employers who are legally responsible for employees and clients also have the same right?
I honestly don't know what the "right" answer is, but it is nowhere hear as black and white as people want it to be. There simply isn't a "yes" or "no" answer to this matter. But ignoring it won't make it go away.
And as for those worried about the two tier society - we have plenty of tiers in society already. One more is irrelevant. But may actually be more necessary than some of the ones we happily live with all the time.
