Agreed. Potential immediate aches/pains/reaction are nothing versus unknowable potential longer-term ramifications. As I understand it, these vaccines are completely different from any other prior vaccine in that they are entirely *novel* in approach. And not well tested. So, basically, there is a worldwide experiment underway. No telling how it will work out. This is completely (ultimately criminally?) downplayed in the push to get people to consent to vaccination.
If you are younger and your 25 Hydroxy vitamin D3 level is in the 60-80ng/ml range, your odds of being killed or harmed by this virus are miniscule, and taking the vaccine would be a senseless risk. If you are older, higher risk with co-morbidities, if 'long-term' for you means say 5 or 10 years, then perhaps consenting to the vaccine is a sensible gamble. IMO.
