Study Title: Aluminum-Adsorbed Vaccines and Chronic Diseases in Childhood: A Nationwide Cohort Study
Publication: Annals of Internal Medicine
Key findings:
No Association found: The study found no association between cumulative aluminum exposure from early childhood vaccinations and an increased risk of any of the 50 chronic disorders assessed. Specific Disorder Groups:
Autoimmune Disorders: Adjusted hazard ratio of 0.98 (95% CI, 0.94 to 1.02) per 1-mg increase in aluminum exposure. Atopic or Allergic Disorders: Adjusted hazard ratio of 0.99 (CI, 0.98 to 1.01) per 1-mg increase in aluminum exposure. Neurodevelopmental Disorders: adjusted hazard ratio of 0.93 (CI, 0.90 to 0.97) per 1-mg increase in aluminum exposure.
Incompatibility with Larger Risks: For most individual outcomes, the study’s findings were incompatible with relative increases in risk greater than 10% or 30%.
limitations: Individual medical records were not reviewed.
Conclusion: The study did not find evidence to support an increased risk of autoimmune, atopic/allergic, or neurodevelopmental disorders linked to early childhood exposure to aluminum-adsorbed vaccines.However,small relative effects,especially for rarer disorders,could not be statistically ruled out.
Study Design:
Type: Cohort study
Data Source: Nationwide registry data (vaccinations, diagnoses, confounders)
Setting: Denmark
Timeframe: 1997 to 2020
Participants: 1,224,176 children born in Denmark between 1997 and 2018, alive and residing in the country at age 2.
Intervention Measured: Cumulative aluminum amount received through vaccination in the first 2 years of life.
Outcomes Measured: Incident events of 50 chronic disorders (autoimmune, atopic/allergic, neurodevelopmental).
Background:
aluminum is used as an adjuvant in nonlive vaccines.
There are ongoing concerns about potential links between aluminum-adsorbed vaccines and chronic autoimmunity,atopy/allergy,and neurodevelopmental disorders.
Large-scale safety data were limited.
Funding:
* Primary Funding Source: None.In essence, this study, conducted in Denmark with a large cohort of children, found no evidence that aluminum in vaccines increases the risk of autoimmune, allergic, or neurodevelopmental disorders.
