Which animal's spinal cord did Louis Pasteur use to cultivate and weaken the virus for his landmark rabies vaccine?
Tap your pick
Louis Pasteur developed the rabies vaccine by transmitting the virus through rabbits and then drying their spinal cords to weaken the pathogen. In 1885, he successfully used this vaccine on Joseph Meister, a nine-year-old boy mauled by a rabid dog. Interestingly, Pasteur was not a licensed physician, which made treating the boy a significant legal and ethical risk at the time. Photo: Whispyhistory, Wikimedia Commons, CC BY-SA 4.0.
