A comment on the website read as follows:
“Perhaps the food allergy problems are linked more to the genetic engineering of our food. I have a young son with celiac disease, alopecia, and thyroid issues. He has never been vaccinated and he had a natural child birth. I am a non vaccinator but I don’t think that the vaccines are the whole issue. There is so much propaganda on all sides that it is impossible to make a clear argument for or against. My reasons for not vaccinating my child were from both a medical standpoint and a biblical one. We should be looking at the whole picture rather than focusing on the vaccines. I imagine that there is much money to be had by taking the anti stance and promoting a biased view. Until someone decides to take a truly unbiased view we will have to rely upon our gut as parents to do what is best for our children.”
The immune system is complex beyond belief and I don’t think they’ll ever figure out one factor that contributes to allergies.
I suspect it’s a whole range of factors, and different for each person, depending on genetic inclinations.
