I think the worldwide disruption of the pandemic melted people's brains, and the recent surge in the anti-vax movement is a symptom. Along the lines of: if all this bad stuff happened and my life was significantly harmed, it must be someone's fault; all those doctors and scientists kept advising everyone on what they thought was happening and what to do, so they're probably the ones who caused the problem.

I say this as a committed fan of RNA vaccines and masking, who believed we could have contained covid with more serious lockdowns very early in the pandemic: In point of fact, it was someone's fault, and the someones whose fault it was - the ones doing gain of function research - were the same people who took control of lockdown policy in the US. That would be enough to melt a lot of people's brains, even if it weren't for the psychological effects of lockdowns, remote schooling, and the consequent arrested development of an entire generation. At a bare minimum, the concealment by the CCP of what they knew of covid was an act of war. The cover-up itself killed millions of people and caused untold economic damage to their adversaries, with the collusion of health officials in the US government who had offshored illegal research there.
