I am for one salute all the doctors and nurses who face these viruses and diseases on a daily basis. I am glad that you and your colleagues turned out fine and well.
We can't put blame on people who wouldn't want to take the vaccine as they might have the same reasons as mine, avoiding risk by letting others first.
I am not a doctor, nor have studied to medicine-related courses, but I will trust my gut and think that you're not a fake in this forum.
Please, keep the updates for your second dose of the vaccine, as well as the results a week later after the second one. I'll gladly use your information and insights if I will take the vaccine or not in February.
I will update after my second shot (1st february), but really this drug is already experimented and already administered to maybe a milion of people only in Italy, my experience is only a drop in the sea.
Severe reactions exist but are rare, we don't have data for longer term (years) reactions but I feel pretty confident that the mechanism (i described it above) is pretty safe, maybe safer than a traditional vaccine, although less "natural".
The video is frightening, I did never see seizures like that but I suppose they are possible. Acetilsalicilic acid can cause sudden death, and allergic reactions to simple things like nuts kill people every year. You cannot live without taking risks.
Especially for me, a worker in an hospital setting, the risk of the vaccine is IMHO less than the risk of the covid. One of my collegue lost her smell and taste SINCE MARCH after a covid infection, and this alone would be extremely disturbing for me because I love eating. Also, me and my wife are trying to have a son and the effect of the infection during the first months of pregnancy is unclear, I don't want to act as a vector and infect her. And my parents are almost 80 years old and I saw them like 3 or 4 times in the last year for the fear of killing them.
Value the risk balance and take your choice. Just one more thing, the ethical aspect: you are helping in saving lifes. If we manage to get a sufficient number of people vaccinated, we are out of this. Your choice is going to influence not only your life, but also other's one. The same goes for the mask and everything, flat-earthers does harm to nobody but covid negationists are actually killing people.
