Taking a vaccine is not just about self-protection. It the the route to the much discussed herd immunity, and protects everybody. With a high enough level of immunisation, transmission is suppressed. Vaccines do not prevent people from getting infections, nor do they eliminate infections. They build the herd immunity whereby the ability of a virus to transmit is disrupted. So those who say "I'm not at risk so I won't" are really selfish, and far worse than the people I am sure they attack for not wearing masks or breaking lockdown rules. They are hypocrites.
I am certainly not in favour of forcing people to do anything. But anyone refusing the vaccine when it is available to them should not have the protection of society either - they should have to continue to wear masks, they should have to socially distance and not visit or mix with people indoors. Because they become to the risk to everyone else. Since they are so happy for everyone to have to continue to live like that for their own selfish ends, it shouldn't be too hard for them to continue to do so.
And in answer, not only will I, but I already have. I volunteered the minute it was possible, and was called up a few weeks ago. Because even a trial vaccine is far safer, and the odds far better, than many other things that are risky about life, and I happen to believe that contributing to knowledge and the welfare of the whole human race is worth something. Our ability to be selfless is supposed to be one of the factors that raise us above other animals. What a shame that it is in such short supply. Not surprising, but shameful.
