title: Streptococcal abscesses following diphtheria-tetanus toxoid-pertussis vaccination.
abstract: Abscesses developed in seven children who received diphtheria-tetanus toxoid-pertussis vaccine at a clinic in Indiana. Epidemiologic investigation revealed that all seven children had received vaccine from the same multidose vial and had been vaccinated by the same nurse at the office of one physician. Group A beta-hemolytic Streptococcus was isolated from abscesses in six of the seven children. No source was identified as the cause of this cluster of abscesses. Vaccine of the same lot number used elsewhere was not associated with the development of abscesses. It appears that the vaccine became contaminated during use.
