ELI5: Who benefits financially from the anti-vaccine movement?

I have read opposing views on this topic that both site scientific evidence.  Usually when I'm deciding what to believe I like to "follow the money".  For example, scientific evidence will site that oats are good for you but the study might be funded by General Mills.  

Who benefits financially from telling people not to vaccinate their kids?  I don't understand a direct money trail for that viewpoint.

While "following the money" *can* be a good strategy, it's probably remiss to assume that it *must* be a factor in everything.

The anti-vaccine movement is driven by emotional advocates: people who *think* they have suffered (either directly or indirectly) as a result of vaccination, and have access to *just* enough medical knowledge to make vaguely-true-but-misleading claims, etc. They're not benefitting financially from it; they just genuinely believe it's putting people's lives at risk, and they want to stop it.

The only people who'd make money off it are the lawyers (prosecuting the case), and maybe the 'alternative medicine' crowd pushing their alternative products.
