Marko has a valid opinion. Vaccinating is safer than not. However that is not saying that vaccines are perfectly safe, just that statistically they are safer than nothing.
What amazes me is that a man can pound someone else as "unscientific" and have a huge amount of commentors who are spouting psuedo-science supporting him.
Marko claims that there is no credible evidence linking vaccines and autism. That is false as there are multiple studies that have found varying degrees of correlation between vaccines and autism. One of the problems with "credibility" in science when it comes to public health and safety issues is that each side attacks the credibility of the other side. The IPCC reports are prime examples of political doctrine with a bunch of Ph.D's who signed on. Vaccination has even less serious research going into it than climate change, so we can expect REAL science to move forward at an even slower pace.
As a human being I know that when there is no clear road map we really will try anything to see if there is benefit. Parents of autistic children are no different. But blatantly repeating "Vaccines are safe" and insulting parents who don't agree is not going to solve anything.
