Last year was the year I first encountered the anti-vaccer movement, and such a strange movement it is. People risk serious injury and consequences by not vaccinating. All because they are scared of either autism or the mercury in vaccines (or a combination of both).

Especially the mercury concern is something I don’t understand. As a tuna sandwich contains more mercury than a vaccine, and that’s something most of them eat without a second thought. Or even let their children eat it, while they refuse to vaccinate them.

But the biggest thing I don’t understand is the failure of risk assessment. The following video gives a nice simple demonstration what it means to vaccinate or not. And how the risk of autism, real or not, compares to it. A nice little video to get yourself thinking again after new years eve.
