I going back to reply to the original post. I am new here so just got to reading this thread.
Vaccine? I think this speaks to exactly what is wrong with our world and why so many more people have celiac or NCGI these days. We are thinking the wrong way as a society. A vaccine just covers up a problem; it doesn't deal with the real problem. And the real problem is one, we have bastardized wheat to such an extent that our bodies have not evolved enough to keep up with the changes in wheat, and two, that we have become a wheat/processed carbohydrate dependent society.
We need to get back and look at the real issues here. A vaccine, while handy to some, is not the answer. It's like a band-aid solution. What's next? Will be need a vaccine in the future due to GMO corn, tomatoes, fruit......all because we think we are smarter than the innate Universe that originally designed REAL, honest-to-God food.
More big-pharma and GMO crops are not the answer - they are the problem.
