I never argued for "hasty" or "generalization."
Simple question: which sub-population are you talking about? Please exclude any sub-population where a statistically significant sample of vaccinated individuals already exists, unless your concern is limited solely to long-term side effects.
If you are concerned about long-term side effects, please cite at least one scientific study explaining why you are concerned about that PARTICULAR sub-group being vulnerable to that PARTICULAR side effect - we wouldn't want to waste time if you can't cite any scientific literature supporting your claim
(P.S. I've only made a single comment about vaccinated -vs- unvaccinated, so you might have me confused with someone else in this thread)
