Abstract
The percentage of vaccinated children in a population of 931 three-year-olds was calculated by means of a questionnaire distributed in health centers in Edogawa Ward, Tokyo. The children were divided into two groups according to the presence or absence of allergic disease, and the percentage of vaccine-inoculated subjects and the incidence of side effects were investigated in each group. Vaccination rates were not different between the allergic and non-allergic groups, but the incidence of side effects to DPT vaccine was higher in allergic children than that in the non-allergic group.
We suggested that to reduce or prevent side effects in vaccination of allergic children, improved vaccines should be developed, and then vaccination rate should be increased among the population.
