What are you trying to say? Why is the rate of autism in Canada and the US higher than Cuba's because of... what exactly? Vaccinations?

According to the World Health Organization, Cuba has far better immunization coverage and outcomes than either the US or Canada. The Cuban vaccine schedule targets all Cuban children for immunization against 13 diseases with 11 vaccines and achieves a coverage rate of about 99%. By comparison vaccination rates in the United States for most shots are about 85%. 

So, logically, a better vaccination program in Cuba coupled with a much lower rate of autism suggests either that more vaccinations either reduce the incident of autism, or, more likely, that vaccinations and autism are not linked.

Of course we should be examining the rise of autism. Trump, however, has called into question vaccinations, not autism.
