A 20-year-old college student developed an immunologic hypersensitivity reaction, erythema multiforme minor, 1-2 weeks after receiving a meningococcal conjugate vaccine. He had no history of erythema multiforme, nor had he received any other vaccine or drug therapy. The temporal relationship between the development of erythema multiforme and the vaccination suggests that the meningitis vaccine probably was the causal agent. The occurrence of this distinct cutaneous reaction, with the potential for a serious complication such as erythema multiforme major or Stevens-Johnson syndrome on rechallenge, should serve as a warning against repeated booster vaccinations in patients who develop reactions such as this one.
