No matter how many near-tragedies and public health crises can be directly attributable to the anti-vax movement, the fight to curb its influence is still an ongoing and difficult one.
After all, parents will, naturally, never stop worrying about the well-being of their children and as long as people find the right way to exploit that fear, they can almost guarantee an audience for themselves.
But when a group of people so fervently cry that vaccines cause autism, it becomes very easy to get so caught up in trying to prove them wrong that we miss the uncomfortable implications behind what they're saying.
And those implications are a large part of why the anti-vax movement is causing as many problems for actual autistic people as it is for public health.
