"Impact of Childhood Vaccination on Short and Long-Term Chronic Health Outcomes in Children"

This study found that exposure to vaccination was independently associated with an overall 2.5-fold increase in the likelihood of developing a chronic health condition, when compared to children unexposed to vaccination. This association was primarily driven by asthma, atopic disease, eczema, autoimmune disease and neuro-developmental disorders.

This suggests that in certain children, exposure to vaccination may increase the likelihood of developing a chronic health condition, particularly for one of these conditions.

A total of 18,468 consecutive subjects met eligibility criteria for the study, of which 1,957 had no exposure to vaccination and 16,511 had received at least one vaccine during their enrollment in the plan with various levels of exposure.

There were no chronic health conditions associated with an increased risk in the unexposed group. The overall probability of being free of a chronic health condition at 10-years of follow up was 43% in the group exposed to vaccination and 83% in the unexposed group.

This study, to our knowledge, includes the largest cohort of children completely unexposed to vaccination, with observation in some subjects up to 18 years.
