J Allergy Clin Immunol 2006; 117: 1021-35 In 41 studies with information on the total number of AEs, 1047 adverse reactions in a total of 386,149 doses were identified (2.7 reactions/1,000 doses). In 49 studies with information on the number of patients, the AEs were 529 per 4378 patients (12%). In the trials that specified the severity of reaction, the occurrence of severe AE was 0.56 per 1,000 doses. Overall, 14 serious AEs probably related to the treatment were found.
