Nobel Prize in Physiology or Medicine
On October 3, 2011, Ralph M. Steinman was posthumously awarded the Nobel Prize in Physiology or Medicine for his discovery of the dendritic cell and its role in adaptive immunity. Steinman's discovery was crucial in the development of new therapeutic strategies for vaccines and diseases like cancer. Notably, the Nobel Prize was announced just three days after Steinman had passed away from pancreatic cancer, which led to a unique situation where the prize was awarded despite the Nobel committee's rules against posthumous nominations.
