I did spend much of last February and March in London. Then last summer, we moved back to the UK for two or three years, although not to London.
Yes, of course my attitude towards Covid and the vaccines is influenced by my dad's illness (nothing to do with Roger Federer!), although I did have the same opinions previously. I honestly would get my cats vaccinated asap if I were able to!
I do agree with you that Covid shows up that our society and environment are not doing well and need to be improved. However, I don't think that that means not caring about the fate of existing human beings whose suffering needs to be tended to.
1) Most people who are skeptical about the vaccines are substantially under-estimating the risk that Covid poses to them and at the same time substantially over-estimating the risk that the vaccines pose to them. For example, there's been a lot of talk about myocarditis on these threads as a reason not to get vaccinated. However, just this week, even the famous vaccine skeptic Joe Rogan had to admit that data show that in all age groups the risk of myocarditis is many times higher from Covid itself than it is from the vaccines.
Moreover, many are pointing to the VAERYS statistics showing many adverse reactions to vaccines in the USA, including 10,000-11,000 deaths. However, VAERYS data are self-reported and when the CDC studied those deaths they could only show that nine of them were caused by the vaccines. But even if all of them were caused by the vaccine, that is still only about 1/80th of the deaths from Covid in the USA. In short, the vaccines are much safer than most skeptics think they are, and Covid is more of a threat than many realize. The vaccines are doing a decent job at preventing serious illness and especially death, and even with transmission, it seems to me that they are still doing something (not as much as with prior variants, admittedly).
2) Even if there were people who were at more risk from the vaccine than from Covid itself, I still think they ought to get the vaccine, because the primary reason to get the vaccine is to prevent the spread of Covid. When I got the vaccine, I didn't think that I would get seriously ill if I got Covid, but I would feel absolutely terrible if I got Covid and transmitted it to someone who did get seriously ill because of Covid. One way in which I clearly am influenced by my dad's illness is that I get extremely angry when I read that, "Only old and ill people die of Covid," as though that means it doesn't matter. Of course it matters! My dad turns 76 in the next week or two so he is not young by any means, but he could live another decade, maybe more. Even people in their early 60s are at substantially increased risk of Covid and many of them will live another three decades if they don't die of Covid.
Even a small reduction in transmissibility for each individual can mean a major reduction in case load overall, so even with Omicron, the vaccines can help with overall spread (and even more so with hospital resources, which are seriously overstretched). I wrote a different post about this yesterday or the day before. So, while you are obviously at your discretion to take or not take whatever medicines you like if it's not treatment for an infectious disease, I think we all have a moral obligation to get the vaccine to minimize the risk that we'll harm someone else. If we don't get the vaccine, we should take other precautions such as wearing masks and such as distancing if exposed or positive. The fact that Novak did the L'Equipe interview while positive, didn't tell the interviewer or photographer, and took his mask off for the photos suggests to me in the strongest possible terms that he is not thinking about the danger he poses to others.
I agree with you that if someone is suffering they shouldn't have to stay alive, but I don't think we should take that decision for them without some word from them. (A good reason to write a living will!)
