I work in medicine/health care and anti-vaxxers really, really piss me off. Idiots try to tardsplain medicine to me every day but they can usually be ignored and/or told to fuck off with little consequence, the difference with anti-vaxxers is that they're fucking dangerous. There is also harm done by people who refuse to take their kid to the doctor until they're half dead, which is also neglect with a dash of stupidity, but oddly enough the anti-vax people tend to be the opposite end of the spectrum (bring their kid in for every little thing and liberally abuse the ER). Here they do have a "mandatory" vaccination schedule you must follow if you want your kid to attend school, but you can apply for an exemption on the grounds of "I don't fucking feel like it" so it's kind of useless. Unvaxxed kids can be given the boot in the event of an outbreak but that's likely an ass covering measure rather than a serious piece of public health legislation. Personally I think vaccination should be required to access any public health or education services and exemptions should be at the discretion of a doctor only, but I can't see it ever happening.
