Sterne's Vaccine
The Austrian-South African immunologist Max Sterne (1905-1997) developed an attenuated live animal vaccine in 1935 that is still employed and derivatives of his strain account for almost all veterinary anthrax vaccines used in the world today. Beginning in 1934 at the Onderstepoort Veterinary Research Institute, north of Pretoria, he prepared an attenuated anthrax vaccine, using the method developed by Pasteur. A persistent problem with Pasteur's vaccine was achieving the correct balance between virulence and immunogenicity during preparation. This notoriously difficult procedure regularly produced casualties among vaccinated animals. With little help from colleagues, Sterne performed small-scale experiments which isolated the "Sterne strain" (34F2) of anthrax which became, and remains today, the basis of most of the improved livestock anthrax vaccines throughout the world.

Famous quotes containing the word sterne:
“Digressions, incontestably, are the sunshine;Mthey are the life, the soul of reading!—take them out of this book, for instance,—you might as well take the book along with them;Mone cold external winter would reign in every page of it; restore them to the writer;Mhe steps forth like a bridegroom,—bids All-hail; brings in variety, and forbids the appetite to fail.”
—Laurence Sterne (1713–1768)
