There is plenty of evidence that some antivaxxers have deep-seated fears towards vaccines and their irrational behaviour and negative stance towards vaccines isn't easily resolved.
It would appear it's a long and slow process rehabilitating some antivaxxers and some are probably too far gone down the rabbit hole of pseudoscience and conspiracy to ever be cured of their irrational fears. This is a sad situation for the individuals concerned but government can only do so much, and the focus in these extreme cases may be to minimize the damage they inflict on society due to their persistent posting in social media sites.
