The discovery of penicillin changed the world of medicine enormously. With its development, infections that were previously severe and often fatal, like bacterial endocarditis, bacterial meningitis and pneumococcal pneumonia, could be easily treated.....and let's say that you are in 1920 have an tonsil infection ,that is very easy to get what would you prefer the discovery of penicillin or the rabies -vaccine?
