There have always been anti vax conspiracy theorists banging on in the background.
Since that discredited Wakefield cunt, had that 'study' printed in The Lancet, people have been refusing vaccinations for their children in increasing numbers.
The so called research has been thoroughly debunked, the theory behind it discredited, he has been successfully prosecuted and discharged from medicine, but people don't want to let go of their convictions that vaccinations are painful, harmless and unnecessary.
No one wants to inflict pain on their child and no one wants to see their child upset, but vaccinations are one of those 'cruel to be kind' things that must be done.
People underestimate just how dangerous 'childhood' illnesses are and fail to grasp how some people can fight off an illness with almost no consequences, while others are seriously harmed or killed by the same bug.
