Delay in Vaccine & Reduced Risk of Asthma (PDF)


“Early childhood immunizations have been viewed as promoters of asthma development by stimulating a TH2-type immune response or decreasing microbial pressure, which shifts the balance between TH1 and TH2 immunity.

Results: Among 11, 531 children who received at least 4 doses of DPT, the risk of asthma was reduced to ½ in children whose first dose of DPT was delayed by more than 2 months. The likelihoodof asthma in children with delays in all 3 doses was 0.39 (95% CI, 0.18-0.86).

Conclusion: We found a negative association between delay inadministration of the first dose of whole-cell DPT immunization in childhood and the development of asthma; the association was greater with delays in all of the first 3 doses.”
