The first successful vaccination against yellow fever was developed by Dr. Max Theiler in the 1930s, but prior to that, yellow fever was a significant public health threat in the 19th century. The first known deaths from yellow fever can be traced back to outbreaks in the late 17th century, particularly in places like the Americas. However, the specific question regarding "doctor dieginos" seems unclear or may contain a typographical error, as there is no widely recognized historical figure by that name associated with yellow fever.
