Children Developing Gastro Intestinal Symptoms after Oral Polio Vaccination - Beware of CMPA

Child hood immunization to prevent infectious diseases was one of the most successful health care steps in the last century. Presently allergy is increasing all over the world. Cow’s Milk Protein Allergy is the commonest food protein allergy in infancy, at the highest vaccine receiving age of life. Few children with CMPA showed Gastrointestinal symptoms like diarrhoea, vomiting and screaming episodes following Oral Polio Vaccination. This initiated the following retrospective observational study to see the present relation and pattern of reactions after polio vaccination in children with CMPA and whether this type of reactions can give a hint towards diagnosis of CMPA in undiagnosed or missed CMPA cases.
