Re: herd immunity
Somebody has never heard of herd immunity. There are actually genuinely good reasons for specific people not to get vaccinations, so you need to hit another % of vaccinated population or the entire system breaks down and you end up killing the people who through no fault of their own can't be vaccinated. Personally I think it should be an executable offence but I'm old fashioned like that.
There's a lot of very nasty diseases out there that we're lucky in the west to be able to be vaccinated against safely, relatively cheaply and efficiently. People taking that for granted drive me wild.
