You should read more about this guy. He was responsible for the research, methodology, and practices that created modern vaccination. It was so thoroughly accepted by WWI that every soldier and sailor was vaccinated with about dozen different serums. It is believed that this was what caused the 1918 Spanish Influenza.
Vaccines were invented in the 1700s by a White man named Edward Jenner, not some kike in the 1900s.
Even if the kike you mentioned did "invent" vaccines, it is well established that kike "scientists" steal every idea they have.
