Why is childhood arthritis on the rise?

Several months ago I began receiving a newsletter from a group called PROVE--Parents Requesting Open Vaccine Education. They are based out of Texas and I have received many wonderful updates from them. This article on childhood arthritis really hit home. As you know, my oldest daughter was diagnosed with juvenile rheumatoid arthritis, JRA, at age 3. Dr. Tenpenny helped me understand what had happened to my sweet little girl. Celeste, my daughter, does have a genetic propensity to the disease as her paternal grandmother has it, also.
