Wild smallpox case occurred in 1949.
How was smallpox vaccine discovered. Successful use of smallpox vaccine led to the gradual reduction of smallpox cases. The use of RNA as a vaccine tool was discovered in the 1990s in the form of self-amplifying mRNA. When Edward Jenner invented the smallpox vaccine in 1796 by taking fluid from a cowpox vaccine and scratching it on to the skin of a young boy he.
The smallpox vaccine was discovered by an English scientist Edward Anthony Jenner from Berkeley Gloucestershire. But smallpox was also one of the first diseases to be controlled by a vaccine particularly following the great experiments of English physician Edward Jenner in 1796.

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. After intensive vaccination campaigns in the 1960s and 1970s the last case of wild smallpox.
