Analysis of health outcomes in vaccinated and unvaccinated children: Developmental delays, asthma, ear infections and gastrointestinal disorders
This study on children from three medical practices found higher rates of developmental delays, asthma, and ear infections among vaccinated children compared to unvaccinated children. However, a significant portion of children didn't receive all recommended vaccines, and the study lacked important demographic information, limiting its conclusions. Also, it is unclear whether the effect estimates would remain after controlling for parental education, which is known to be linked to vaccination hesitancy.
