Two Professors In Medical School Cited For Vaccine Aid

Two professors in the Harvard Medical school, Dr. Andrew W. Sellards and Dr. Hans Theiler are cited in a report made to the French Academy of Sciences for having contributed important aid to Dr. Jean L'Aigret of the Pasteur Institute of Tunis, in perfecting a wholly successful vaccine for yellow fever.

Dr. Theiler used mice and monkeys as the subjects for the initial experiments, and when Pasteur authorities refused permission to inoculate persons as a final test, the doctors transferred their activities to Tunis, where the experiments were continued.

After convincing the director of the Pastcur Institute in Tunis of the efficacy of the vaccine,and gaining the permission of the governor of West Africa, 3,000 whites were successfully inoculated against the dread yellow fever. The Pasteur Institute of Paris is being urged to begin production of the new vaccine.
