If you can’t change the minds of the antivaxxers, you have to take the decision out of their hands and make it compulsory to have your children vaccinated. It’s everybody’s health that’s being put at risk by these numbskulls.
It is not everyone's health at risk. It is the health of their own children and that of children who are unable to be vaccinated.
The urgency, imo, is not sufficient to override the principle that medical intervention requires consent. The problem could probably be minimised by checking which children have not been vaccinated and ensuring that the issues are talked through with their parents - oh dear this costs money! Maybe the parents should be charged for weekly checks to certify that their children had not become infectious?
At the same time, much could be done to stop the internet and social media providers distributing false and misleading information and propaganda, and blocking malicious systems designed to undermine our society. But, oh dear, FB might lose advertising revenue when people stop clicking on inflammatory crap!
