From the article:
“The study was based on medical records of over 2000 children born between November 2005 and June 2015. The study followed children continuously for a minimum of 3 years from birth. Vaccination status was determined based on any vaccination received prior to one year of age which yielded 30.9% of the children in the unvaccinated group. Results show that vaccination before one year of age led to significantly increased odds of medical diagnoses of developmental delays, asthma and ear infections in children.
In a separate analysis, children receiving more vaccines by one year of age were more likely to be diagnosed with gastrointestinal disorders compared to those who received no vaccines within the same timeframe. In temporal analyses, children vaccinated prior to six months of age showed significant risks of each of the disorders studied as compared to unvaccinated children.”
