TULAREMIA VACCINE

A report on the efficacy of a vaccine for tularemia by Saslaw and associates of the Ohio State University Health Center has been published in the current issue of Archives of Internal Medicine. Thirty-one male volunteers, inmates of the Ohio State Penitentiary, were the experimental subjects. These included a vaccinated group of 14, a nonvaccinated group of 4, and a control group of 8.
