“Parental asthma and nasal allergy increase asthma incidence in offspring up to adulthood. Avoiding tobacco smoke exposure during pregnancy, receiving vaccinations in early childhood, and starting day care between 1.5 and 3 years of age might prevent or delay the development of asthma.”

“The prevalence of allergic diseases and non-specific infections in children and adolescents was not found to depend on vaccination status.
Protective vaccinations are among the most important and effective preventive measures in modern medicine (1). They make a substantial contribution to reducing the probability of contracting many infectious diseases as well as their severity. The immediate goal of a vaccination is to protect the vaccinated person from a disease. Achieving high rates of vaccinated persons additionally results in the so called herd immunity.

“We use data from the Cebu Longitudinal Health and Nutrition Survey (CLHNS) in the Philippines to link vaccination in the first 2 years of life with later physical and cognitive development in children. We use propensity score matching to estimate the causal effect of vaccination on child development. We find no effect of vaccination on later height or weight, but full childhood vaccination for measles, polio, Tuberculosis (TB), Diphtheria, Pertussis and Tetanus (DPT) significantly increases cognitive test scores relative to matched children who received no vaccinations. The size of the effect is large, raising test scores, on average, by about half an SD.”
