The problem
Intervention: Timely neonatal BCG-M and hepatitis B vaccination
Who it was tested with: 2,279 children born between 2018 and 2022, followed to 36 months of age.
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"AD incidence was comparable between vaccinated (20.5%) and non-vaccinated (17.5%) children (chi-squared with Yates' correction, p = 0.192), indicating no statistically significant overall impact of immunization on AD risk." The study uses cohort comparison between vaccinated and unvaccinated groups with statistical testing to evaluate the relationship between vaccination and outcome.
Observational study design cannot definitively establish causation; country context not specified; potential for confounding by factors not measured or adjusted for; follow-up limited to 36 months.
