It is sad that the intelligence of the average person is now so low that we must use dumbed down cartoons to communicate with them.
Post Hoc Ergo Procter Hoc. While you may well be correct, this specific argument is fallacious and can not lead to a valid conclusion.Since the anti vax campaigns where fewer people are being vaccinated there have been several measles outbreaks in the USA. What does THAT lead you to believe?
Dr. Watt obviously knew the number of unvaccinated cases. Thus his ability to claim a "significant" number. In science, "significance" usually means statistical significance. So where the heck are the statistics showing the significance? The lack of such references leads me to believe that in fact specific statistics do not strengthen his case. i.e. that there was also a "significant" number of cases among the "immune herd".
