There are so many layers to unravel before many people will trust pharmaceutical companies. It doesn't help that Marxists (naturally the most charismatic and wise advocates, so well respected in communities and likely to be listened to) are usually the ones most critical of bourgeois governments and big pharma.

I have a rather low opinion of anti vaxxers but like you, I don't hate them; we can't hate them until they've ignored us after we've instigated a system of revolutionary education. But to blame them personally in the meantime? I don't see many revolutionaries rolling out educational programs nowadays. Not near me at least. I don't have stats but most of the anti vaxxers I know (it's unfortunately quite a few) are not well educated.
