Dr. Weeks’ Comment: Comparing outcomes of vaccinated kids with unvaccinated kids helps us appreciate the pros and cons of vaccinations. But Big Pharma has resisted doing these essential studies. Now we have some damning data to access.

The aim of this study was to compare the health of vaccinated versus unvaccinated pediatric populations. Methods: Using data from three medical practices in the United States with children born between November 2005 and June 2015, vaccinated children were compared to unvaccinated children during the first year of life for later incidence of developmental delays, asthma, ear infections and gastrointestinal disorders. All diagnoses utilized International Classification of Diseases–9 and International Classification of Diseases–10 codes through medical chart review.
Subjects were a minimum of 3 years of age, stratified based on medical practice, year of birth and gender and compared using a logistic regression model. Results: Vaccination before 1year of age was associated with increased odds of developmental delays (OR=2.18, 95% CI 1.47–3.24), asthma (OR=4.49, 95% CI 2.04–9.88) and ear infections (OR=2.13, 95% CI 1.63–2.78). In a quartile analysis, subjects were grouped by number of vaccine doses received in the first year of life. Higher odds ratios were observed in Quartiles 3 and 4 (where more vaccine doses were received) for all four health conditions considered, as compared to Quartile 1. In a temporal analysis, developmental delays showed a linear increase as the age cut-offs increased from 6 to 12 to 18 to 24months of age (ORs=1.95, 2.18, 2.92 and 3.51, respectively). Slightly higher ORs were also observed for all four health conditions when time permitted for a diagnosis was extended from⩾3years of age to⩾5 years of age.
In this study, which only allowed for the calculation of unadjusted observational associations, higher ORs were observed within the vaccinated versus unvaccinated group for developmental delays, asthma and ear infections. Further study is necessary to understand the full spectrum of health effects associated with childhood vaccination.
In this study, based on a convenience sample of children born into one of three distinct pediatric medical practices, higher ORs were observed within the vaccinated versus unvaccinated group for developmental delays, asthma and ear infections. No association was found for gastrointestinal disorders in the primary analysis, but a significant relationship was detected in the third and fourth quartiles (where more vaccine doses were administered), at the 6-month cutoff in the temporal analysis, and when time permitted for a diagnosis was extended from children ⩾ 3 years of age to children ⩾ 5 years of age. Similar results have been observed in earlier studies by Mawson et al.3 and Delong.20 The findings in this study must be weighed against the strengths and limitations of the available data and study design, which only allowed for the calculation of unadjusted observational associations. Additional research utilizing a larger sample from a variety of pediatric medical practices will yield greater certainty in results and allow for the investigation of health conditions with lower prevalence, such as autism. A thorough evaluation of vaccinated versus unvaccinated populations is essential to understanding the full spectrum of health effects associated with specific vaccines and the childhood vaccine schedule in totality.
