Dear Terrible Scientist,
So what's the real connection between vaccines and autism?
-I Luv Terrible Science
I decided not to vaccinate myself and as you can see, I'm totally fine.

It's well-known that vaccines do not cause autism; however, a research paper published in 2016 concluded that autism causes vaccines.
The problem with giving even a joking answer to this question is that someone, somewhere will miss the satire and proceed to not vaccinate their child because of it.
