Turkey (then Ottoman Empire)
Typhoid inoculation: The Ottoman surgeon, Dr. Haydar Cemal wrote "on the order of the Chief Sanitation Office of the Third Army in January 1916, when the spread of typhus was an acute problem, innocent Armenians slated for deportation at Erzincan were inoculated with the blood of typhoid fever patients without rendering that blood 'inactive'".
