Vaccine advocates – although propagandists would be a more accurate term – often correctly claim that there is no scientific evidence proving that vaccines have ever killed anyone or caused autism. Therefore, they claim vaccines can be considered the cause of nothing but a cure for cancer, an end to war and the elimination of all human disease except that caused by dirty, unvaccinated children who are homeschooled by religious bigots. To even consider the mere possibility of questioning the intrinsic and perfect goodness of vaccines, any vaccine given for any reason, is to be not only anti-science, but personally responsible for murdering anyone who died of a disease that would have been prevented by vaccination.
The reason that the vaccine propagandist claim is correct is because there is also no scientific evidence that vaccines have not killed anyone or caused autism, because there is absolutely no valid scientific evidence on the matter. Most of the “science” in the studies that are widely cited by those who insist that vaccines are safe are simply statistical reviews, which involve as much use of actual science as polling former Playboy models. In the very few cases where an actual scientific experiment has been performed, the populations compared have not been between a vaccinated group and an unvaccinated control group, but rather two different groups that are both vaccinated to varying degrees.
The vaccine propagandists defend the failure of scientists to gather scientific evidence by begging the question. They insist that it would be unethical to permit a control group of children to go without vaccination, due to their assumption that the risks of vaccination are significantly outweighed by the dangers of the diseases vaccinated against. Thus, they perpetuate ignorance on the actual safety or danger of the current U.S. vaccine schedule.
Day goes on to argue that "It is estimated that between 90 percent and 99 percent of all vaccine-related events go unreported" because infant deaths reported as Sudden Infant Death Syndrome (SIDS) are actually because of vaccines.
