The 8th wonder of the world: One of the biggest inventions that has changed the world

Edward Jenner is considered the founder of vaccinology in the West in 1796, after he inoculated a 13 year-old-boy with vaccinia virus (cowpox), and demonstrated immunity to smallpox. In 1798, the first smallpox vaccine was developed.

The word vaccine is something that is used so commonly, but its origin is actually based on the Latin word for cow, which is vacca, and for cowpox which is vaccinia; therefore, Jenner decided to call this new ‘inoculation’ procedure vaccination.

 This is a timeline of the development of prophylactic human vaccines.
