My sweet uncle (who suffers from asthma) asked me several months ago if I'm going to take the vaccine, and I told him no, because of the possible side effects and unknown long term effects. He said he's also unsure. But his wife is kinda pro-vax, so I didn't push anything as I didn't want to cause any friction, and also because ultimately it's his own choice. So, we didn't talk about it that much since then.
Well, not too long ago, he took the Pfizer vaccine, after many talks with the GP who reassured him. On day 5 or so, he woke up in the middle of the night with a strange sensation over his body, he stood up from his bed and his whole body started to itch, he couldn't breathe anymore and he knew for 99% that he was going to die, that this was it, that he's going to die from the vaccine. His body was frozen, he couldn't move, but he managed to drop himself to the floor. Afterwards, he was able to breathe a bit and gain a bit of energy to scream to wake his wife up. Thankfully she woke up, he was taken to the hospital, got treatment and is doing well now. He will be referred to an allergy institution or something where they will do tests to see if there's a component from the vaccine that he's allergic to.
I told him hopefully he'll get the corona pass without ever having to vaccinate again, because he can now show the strong reaction he has to it. But it'll probably depend on the results from that institution. I'm just relieved he's okay now.
