Résumé :

[BDSP. Notice produite par INIST 0s0R0xPB. Diffusion soumise à autorisation]. Objectives. Most vaccine safety data present only the postvaccuntion incidence of all adverse events rather than an estimate of attributable risk. This study sought to illustrate the difference between the 2 estinstes with data from a hepatitis B imnamization program. Methods. The incidence of health problems occurring before and after each dose of hepatitis B vaccine in a cobort of 1130 children were compared. Results. Although 47.5% of all children reported an adverse event during the 4 weeks following each of the 3 doses, adverse events attributable to immunization occurred in only 10.6% of children. Conclusions. Postimmunization incidence systematically overestimates the risk of adverse events, Estimating actual attributable risk is recessary to avoid false attributable risk is recessary to avoid false beliets regurding immunization.
