There are many who are ignorant of medicine, some of them actually have a medicine degree.
However you don't have to be a medic to interpret a graph that shows a clear decreasing path in time independent of vaccines. How is that possible? apparently there more important factors than vaccines in relation to the decrease of illnesses, such as improvements in food and health.

On a personal note: you can always ask for forgiveness, no no, not to god, I mean to @canadian-coconut for your lack of etiquette. I also advice you to have a quick look at the source of the graph, breath some times, and then answer this post, with style, you know, not with a childish attitude that most readers just avoid.
