Mark Crislip, M. D. has this to say, in Amanda Peet is My Hero1
Green our vaccines? The only green you will see by getting rid of vaccines or decreasing their use is the grass growing on the graves of children needlessly killed by preventable infections.
He deflects the usual "conflict of interest" argument with:
In the interests of full disclosure, I am an Infectious Disease doctor. I make a living from treating diagnosing and treating infections. I don’t make dime one if people do not get infected, so I am against any and all vaccines as they cut into my bottom line2
1 I would not have used the term parasites, however, to characterize parents who do not vaccinate their children. Freeloaders? Sponges? Ignorant? Uninformed? Dumb as a box of rocks? Incompetent? Child abusers?
