I concur @garethnelsonuk one article and a few likes can get people into a total spin about anything.

Growing up in Africa we got vaccines at school, the nurses arrived you took the shots and got given a sweet, that was it. OK so in today's world parents have to give permission, agree but also disagree since if you protect a nation all should have the vaccinations.

Fast forward to the parents of today, science has developed and new findings happen daily, some right and perhaps some take a few years to be proven wrong. Before this generation we never heard of Autism nor Aspergers, now I know of 50% children known to me suffer with either or both diseases.

Modern disease? Additives to foods? Crop spraying? Water recycling? Dirt in the oxygen we breathe? Vaccinations? I do not believe there are any simple answer to the question, however moving forward we do not protection.
