A peer-reviewed study published this month in the Journal of Translational Science found children who were fully or partially vaccinated were diagnosed with autism, severe allergies, gastrointestinal disorders, asthma, recurring ear infections and ADD/ADHD more often than children who were completely unvaccinated.

The study also showed there was a protective effect against these disorders when children were unvaccinated and breastfed for a minimum of six months, or unvaccinated and born vaginally.

The study, “Health Effects in Vaccinated Versus Unvaccinated Children, With Covariates for Breastfeeding Status and Type of Birth,” is based on a cohort of 1,565 children from three medical practices in the U.S.

Within the three practices, parents completed questionnaires based on their children’s vaccination status and health. Results of questionnaires were confirmed using chart records from each practice.

According to the study:

“The findings in this study must be weighed against the strengths and limitations of the available data and study design. Additional research utilizing a larger sample from diverse medical practices will yield greater certainty in results, essential to understanding the full scope of health effects associated with childhood vaccination.”

The research adds to a growing body of literature demonstrating that unvaccinated children are healthier. Similar studies have been published previously by Hooker and Miller (2020), Lyons-Weiler and Thomas (2021) and Mawson et al. (2017).

“This study provides another very important piece of evidence regarding the overall health of vaccinated versus unvaccinated children,” said co-author Brian S. Hooker, Ph.D., P.E., Children’s Health Defense chief scientific officer and professor of biology at Simpson University.

“It is imperative that health officials take this research seriously for the best protection of children in the U.S. and worldwide,” Hooker said.

Hooker said that given the study’s results, “it is imperative” the Centers for Disease Control and Prevention opens up its own Vaccine Safety Datalink to independent researchers so additional study on the effect of the entire infant/child vaccination schedule may be ascertained.

Neil Z. Miller, a medical research journalist, director of the ThinkTwice Global Vaccine Institute, co-authored the study with Hooker.
