I think she may be more weird in real life than the character she plays on Big Bang Theory.

I just can't abide by people who don't vaccinate. They really seem to have neglected all the dead children throughout history who died of measles, mumps, rubella, tetanus, diphtheria and everything else. Children no longer die of these diseases because of vaccinations. I chose to vaccinate because 1) I didn't want my kid to get any of those diseases and 2) I wouldn't dare want to be responsible for my kid being a carrier of one of those diseases and get some other kid sick.
