This study aimed 1) to compare vaccinated and unvaccinated children on a broad range of health outcomes, and 2) to determine whether an association found between vaccination and neurodevelopmental disorders (NDDs), if any, remained significant after adjustment for other measured factors. Vaccination remained significantly associated with NDDs after controlling for other factors, and preterm birth coupled with vaccination was associated with an apparent synergistic increase in the odds of NDD.
