Edward Jenner used cowpox material to create immunity to smallpox. The vaccine is given using a bifurcated two-pronged needle that is dipped into the vaccine solution. The two main categories of mRNA vaccines are non-amplifying conventional viral delivery and molecular self-amplifiying mRNA non-viral delivery.

More than two decades later there was Edward Jenner a doctor from England who is usually credited with the discovery and whose rigorous scientific approach helped the idea of vaccination take off more widely.
