The US Army!: The US Army needed some way to reduce meningitis in recruits during the Vietnam war. Army doctors developed the first meningitis vaccine in the early 1970s. Vaccines aren't "discovered," they're created through rigorous research. The first one was for smallpox, which is now eradicated! The word "vaccine" is the name of cowpox which you get to gain this immunity. Thanks Dr. Edward Jenner!
