Our eldest grandson (15) was born in 2002 when there was MMR scare suggesting it could cause autism. His parents decided not to have him vaccinated. He is the only one of our grandchildren to be diagnosed as autistic. All the others had their jabs. He had his in the end too, after the diagnosis.
When I was born in 1950 it was obligatory in my home for all children to be give the vaccinations, which were available in those days. I am not sure if that is still the case today.
It is crazy to deny your child vaccinations, unless they have a medical problem, which would be made worse if they are vaccinated.
