A recent study from Australia found that delayed vaccination with the first dose of Diphtheria, Tetanus, and acellular Pertussis(DTaP)-containing vaccine is associated with reduced risk of atopic dermatitis (aOR: 0.57; 95% CI: 0.34-0.97, P = 0.04) and reduced use of medication against atopic dermatitis (aOR: 0.45; 95% CI: 0.24-0.83, P = 0.01)(Kiraly et al., 2016).
