Study of Typhus Vaccine
Drs. Rolla E. Dyer and Norman H. Topping of the U. S. Public Health Service, Washington, D. C., have gone to La Paz, Bolivia, to study the effects of a typhus vaccine developed at the Rocky Mountain laboratory of the service at Hamilton, Mont. A news report pointed out that the test was urgently needed because of the possibility that American troops might have to go into regions of South America where typhus exists and also that the United States may supply Britain with the vaccine. Sufficient vaccine for five thousand persons has been sent to Bolivia, which has the highest typhus rate in the Western Hemisphere, it was said.
