In 1930, following on the 1909 discovery of Charles Nicolle that lice were the vector of epidemic typhus and on the work for the vaccine for the closely related Rocky Mountain Spotted Fever, Weigl took the next step and developed a technique to produce the vaccine by growing infected lice and crushing them into a vaccine paste. Year 1930 ( MCMXXX) was a Common year starting on Wednesday (link will display 1930 calendar of the Gregorian calendar.

He refined this technique over the years until 1933 when he performed large-scale testing. Year 1933 ( MCMXXXIII) was a Common year starting on Sunday (link will display full calendar of the Gregorian calendar. The method specifically broke into 4 major steps:
Growing lice meant feeding them blood, the more human the better. At first he tested his method on Guinea pigs but around 1933 he commenced large-scale testing on humans, feeding the lice on human blood by letting them suck on human legs through a screen. The Guinea pig (also commonly called the cavy after its scientific name Cavia porcellus) is a species of Rodent belonging to the family Caviidae Year 1933 ( MCMXXXIII) was a Common year starting on Sunday (link will display full calendar of the Gregorian calendar. This could cause typhus during the latter phase, when the lice were infected. He alleviated this problem by vaccinating the human "injectors" heavily, which successfully prevented them from death (though some did develop the disease). [2] Dr. Weigl himself developed the disease, but recovered.
The first major application of this vaccine was between 1936 and 1943 by Belgian missionaries in China.

This vaccine was dangerous to produce and was hard to make on a large scale. Other vaccines were developed over time that were less dangerous and more economical to produce, including the Cox vaccine developed from egg yolk.
