It is.
You can't argue against it with facts.
A few actually snap out of it when you mention aborted fetus cells being used for vaccine production, but that's only a few.
>They don't know they are being fed lies.
It's a religion.
It's a religion for most quacks and most pharmanarcisists. Same shit there. Mention facts, you get ignored. The follow-up problem is that tons of people believe these religious vaccine-zealots.
So again: what do want to do?
If they haven't figured it out by now that the vaccine is not only useless, but also dangerous, then there is not much you can do. The lies are so blatant and obvious.
This here is about all vaccines. With this shit all other vaccines will end as well, but only when people snap out of their belief.
