No particular expertise was needed to understand submitting to a poorly tested injection (untested medium to long term) employing a radical technology which has never been used as a vaccine, even on livestock, for a virus which poses no meaningful danger to the great majority of people (see IFR data) was obviously foolhardy. That was evident to anyone who did some basic homework before the injections were rolled out. And now we know COVID injections have proven dreadfully dangerous in the short term (see VAERS) while any efficacy wanes rapidly.
