Adverse events following immunization: perception and evidence Jan Bonhoeffer and Ulrich Heininger Purpose of review Introduction The aim of this article is to highlight the evidence on new Immunization safety is a real concern because all vaccines and ongoing vaccine safety concerns in the light of several may cause side effects.

Therefore, maintaining the SMR standard mortality rate success of immunization programs critically relies on public confidence, which is based on public perception. ß 2007 Lippincott Williams & Wilkins Public perception depends on the quality of information 0951-7375 provided. Information about the safety of immunizations needs to be placed on the most rigorous scientific basis possible, because concerns may lead to withdrawal of the product from the market, modification of the pertinent recommendations, or loss of public confidence. Immunization safety concerns often follow a recognizable pattern: the alleged AEFI is a prevalent medical entity of increasing prevalence or unknown cause; the AEFI is suggested to be caused by immunization by some inves- tigators; the methodology of the ‘index study’ (and sub- sequent studies by the same study group) is inadequate (typically poorly or not controlled case series); public communication is made prematurely, resonating with 237 Copyright © Lippincott Williams & Wilkins.
