My pediatrician and I were discussing vaccines. This happens every time I switch practices; I get 'the talk' about not vaccinating my children. The reason I don't is twofold; aborted fetal cell lines in vaccines, and the fact that Isabella contracted Whooping Cough from the old DTP vaccine (discontinued by the way). Christina is already delicate without risking her health to side effects of vaccines.
Here is a link to Dr William Sear's blog where he discusses a potential new study by the CDC into the claims that vaccines cause autism. I will be watching this closely.
For more information about the morality of those vaccines which use fetal cell lines go to Children of God for Life.
