Half the time when I present scientific papers to a pro vaccine advocate that criticize vaccines, they ignore them. Same goes when I provide lectures given by medical professionals that criticize vaccines, again they are ignored. That's hardly "scientific rigour" when you refuse to acknowledge science that criticizes your position.
In fact I provided links to a site or two that provided such such scientific evidence, complete with citations of scientific papers which you can download as pdfs. And I can get you more information if you'd like.
