"I am not 'anti-vaccine.' This is not a change in my stance nor is it a new position that I have recently adopted. For years, I have repeatedly stated that I am, in fact, 'pro-vaccine' and for years I have been wrongly branded as 'anti-vaccine'," McCarthy wrote in the Chicago Sun-Times Saturday.
McCarthy has become a lightning rod in the debate over childhood vaccines. She and Kristin Cavallari have been widely criticized for promoting an anti-vaccine agenda, which flies in the face of science.
McCarthy is insisting she is not "anti-vaccine" at all but simply wants to discuss how many shots a child should get and on what schedule.
"I believe in the importance of a vaccine program and I believe parents have the right to choose one poke per visit. I've never told anyone to not vaccinate," she wrote.
"Should a child with the flu receive six vaccines in one doctor visit? Should a child with a compromised immune system be treated the same way as a robust, healthy child? Shouldn't a child with a family history of vaccine reactions have a different plan? Or at least the right to ask questions?"
Her message, McCarthy insisted in her opinion piece, is that "one size does not fit all."
