Vaccine-related Aluminum exposure closely associated with asthma: Study

A new study conducted by Matthew Daley and colleagues showed a close link between aluminum exposure from vaccinations and persistent asthma. The findings of this study were published in The Official Journal of the Academic Pediatric Association.

Although the childhood immunization schedule is safe and effective, and vaccination rates among US children are still high in comparison to historical averages, sustaining high vaccination rates necessitates maintaining public faith in vaccine safety. This study looked at the relationship between cumulative aluminum exposure from vaccines before the age of 24 months and the incidence of persistent asthma from 24 to 59 months.

The Vaccine Safety Datalink (VSD) conducted a retrospective cohort analysis. Utilizing vaccination records, the total milligrams of aluminum connected with vaccines were calculated (mg). The definition of persistent asthma calls for either one inpatient or two outpatient asthma visits, as well as two prescriptions for long-term asthma control medication. Stratified by the presence or absence of eczema, Cox proportional hazard models were used to assess the relationship between aluminum exposure and the incidence of asthma. In order to account for factors like as birth month/year, sex, race/ethnicity, VSD location, preterm, medical complexity, food allergy, severe bronchiolitis, and health care use, adjusted hazard ratios (aHR) and 95% confidence intervals (CI) per 1 mg increase in aluminum exposure were determined.
