People learn at varying rates and they learn different things, but they do indeed learn. It looks like millions of people have learned that vaccines, at best, don’t work, and at their worst, can be deadly. From eugyppius at eugyppius.com:
Vaccine credulity may still be the mainstream, politically acceptable position, but revealed preferences show that enormous majorities everywhere are done with mass vaccination. Pharmaceutical executives can sing their doubtful hymns to the miraculous safety and efficacy of their jabs, but the quiet worldwide rejection of their garbage products is a stinging rebuke, suggesting that billions across the world harbour unexpressed scepticism towards the mRNA Covid vaccines.
From here, it is only downhill for the vaccinators.
