Like someone else said, Celiac is genetic for some people, how can a vaccine help that. Vaccines are for viruses, to build up antibodies to fight against a virus. Celiac, as far as I understand is not caused by a virus. It is an autoimmune disease, So how can they make a VACCINE against an autoimmune disease. I just don't think it is possible.
It scares me too that they might be wanting to play around with genetics. They are going to cause a lot more problems monkeying around with genetics. It almost feels like they are trying to play GOD. That is a dangerous game they are playing.
