There have been a lot of debates about vaccines in the public forum. We still see literally hundred of thousands of people completely sure that vaccines cause autism, that the ethyl mercury in thiomersal causes alzheimers, and many other spurious assumptions.

Vaccines aren’t perfect (they do carry some risks, but autism isn’t one of them), and the science behind them is pretty complex. Luckily, this little comic does a pretty good job laying out the bigger picture (although it does not mention any of the potential risks outlined in the link above, it does rectify some common misunderstandings.)
