Systemic reactions due to thiomersal.

This article reports on case studies of patients suffering from systematic reactions caused due to the preservative vaccine "thiomersal." The first case study reports on a 66 year-old woman who was admitted with acute urticaria 3 days after she had been vaccinated against influenza with a vaccine containing 0.01% thiomersal concentration. The rash disappeared within a few days without the treatment. The second case study presents information of a 31-year-old doctor, who developed acute urticaria one day after vaccination against hepatitits B with a vaccine containing 0.05% of thiomersal. Both patients presented a sytematic cutaneous reaction after injection of parenteral solutions containing thiomersal as preservative. Since the patch tests revealed sensitization it was believed that systematic reactions was caused due to the presence of Thiomersal.
