I have had both (was Pfizer as I’m HCP) and had a sore arm after 1st, slight headache after second.
I think you should get the vaccine- the side-effects are mild for the vast, vast majority of people. Some people do feel tired after- but I do have my suspicions that at least some of that may have other origins. I have nothing but anecdote and my observations of friends/family/acquaintances/patients to substantiate that, so perhaps rong. But, I have with almost perfect accuracy been able to guess which of the people I know would have “a bad reaction” or feel well “for weeks/months” prior to them having it. So I wonder if self-fulfilling prophecy. I’m not saying that it’s the same in every case, there are good physiological/immunological reasons why you’d have a sore arm/ache all over etc after having a vaccine- your body had to raise an immune response to trigger antibody development. But, for most people that should give rise to short-lived symptoms.
What I can say for sure is that if you catch covid and become seriously unwell, you’ll have some or all of those symptoms- only worse- possibly for many months. Or possibly years, or lifelong (we just don’t know). If you were to contract covid but only have mild symptoms- you could still develop long-covid- all those symptoms and more (chest pain, breathlessness, extend fatigue, palpitations). Of you could have it with few/no symptoms and pass it on to someone who goes on to develop serious illness/long-covid. The problem is, you just don’t know. I genuinely believe the risk of feeling slightly unwell for a short while is vastly outweighed by the benefits of having the vaccine in the vast majority of cases.
If you just want everyone else to have it, so you can see if it works out ok in the long run, I think that’s pretty unethical. What if everyone /far too many to allow efficacy did that? Where would we be?
I think you’re reasons for not having it seem pretty weak, but at the end of the day it’s up to you.
