My response to a similar post on another board:

I mean, medically the vaccines are an abject failure in almost every objective, measurable way, and as predicted, carry severe side effects for a larger-than-negligible percent of the population. The only thing they've been effective at doing is providing geriatric socialists a new means with which to control the movement of people and create a global apartied system (also, as predicted) while lining the pockets of politicians, bureaucrats, and big pharma CEOs.

When for two years, your entire base has been saying this is exactly what was going to happen, and then you get up on a stage and try to pimp vaccines to them, you don't get to act surprised when people react negatively to that.
