I have a mysterious condition that comes with a lot of neurological-type symptoms, but has gone undiagnosed because no test (as yet) has seemed to be able to determine what's wrong. Since for now I am able to live a largely 'normal' life (albeit with accompanying pain and fatigue), I certainly don't want to gamble with the possibility of making it any worse, and for that reason, I have decided not to have the vaccine. I, like many others who, conversely, may have decided to take the vaccine, have a family and a 'self' to take care of and do my absolute best for, and for me, this currently feels like the safest option. I also don't feel we know enough yet about potential long term effects to be comfortable having it.
This is all just my opinion. In an ideal world, everyone should do what is best for them and their family, without fear of judgement or criticism from one side or the other. I personally respect everybody's choice, and would hope to be afforded the same basic courtesy, but sadly suspect this will not be the case.
I do find it depressing when some people are so arrogant as to assume that they know better than somebody else what is right for that person and their own body; whether they are taking the vaccine or not, it's not fair.
All that being said, I don't particularly fancy Covid either, but as an otherwise healthy and young person with a fully functional immune system, I don't consider myself to be at huge risk.
