The study, which used an extensive database of HMO records, contradicts recent research that shows the popular vaccines could cause serious inflammatory bowel disease in children. Crohn s disease affects any area of the gastrointestinal tract including the small intestine. The most common symptoms include abdominal children.
Ulcerative colitis affects the innermost lining of the colon.
People who have it usually experience a progressively loosening and bloody stool, abdominal pain and a severe urgency to have a bowel movement. The findings caused a significant drop in measles immunizations in the United Kingdom. To figure out whether measles shots cause inflammatory bowel disease, Davis and his colleagues reviewed the Vaccine Safety Datalink Study, a database run by the Centers for Disease Control and Prevention containing the medical records of children registered in 4 HMOs from Seattle, Oregon and California. After looking at the emergency room and hospital visits of people registered with the HMOs between 1958 and 1997, investigators identified more than 140 children with Crohn s disease or ulcerative colitis. Researchers then compared the onset of the illness to the patients immunization charts and found no significant evidence that the two were related.
