My personal opinion?'Scientific uncertainty' would err on the side of caution and not roll out an untested (long-term) new-tech Vaccine on the whole world, to combat a disease which - statistically - appears to be as dangerous for healthy 12-50 year olds as other viruses already out there.
This, pre-2020, would be regarded as a totally common-sense approach.
Moreover, i'm interested in your position: what are your views on folk not getting the Covid-vaccine in 2022 (and beyond) and should there be rules or laws to sanction them? Are you planning to partake in further shots and what is your reasoning?
Had a few friends / family members / colleagues either die or suffer serious long term consequences, pre-vaccine roll out. Within the age/health bracket you cite. So for those reasons I personally will get the jab. I'd advocate others getting it too.
However, it is individual choice.
On the original point, you are clearly trying to cause controversy.
