Hoping to have a civil conversation about this. But I find this very worrisome. I don't post this to suggest that vaccines cause all T1D because I know first-hand an unvaccinated child with T1D (I believe there could be countless triggers for T1), but I think it could be a part of a very complex puzzle. We all know that once a person has one autoimmune disease the chance they develop another is significantly higher, so of course I worry about DD and my other kids. I read a book a few years ago on autoimmunity (can't remember the title now) where the author felt it wasn't in the best interest of someone with an autoimmune disease to get vaccinated. That's worried me ever since. And this study only intensifies those worries. The one part that I found surprising about this article was that damaged cells from mice injected into other mice caused autoimmunity in them as well, suggesting that anyone who had an autoimmune disease shouldn't donate blood. Charlotte is only 5 so donating blood hadn't ever crossed my mind. Is there already a "rule" about people with T1D donating blood? http://gaia-health.com/gaia-blog/20...vitably-cause-autoimmune-diseases-plos-study/ http://www.plosone.org/article/info:doi/10.1371/journal.pone.0008382 Just wondering what others' thoughts on this article are.
