The evolution of vaccines
The evolution of vaccinesWho invented vaccination?
It is widely believed that the story of vaccination began with Edward Jenner, but it had, in fact, started nearly a millennium earlier when people in India, China and Africa deliberately exposed themselves to milder strains of a disease in order to protect themselves against more virulent forms. In 1796 Jenner infected a young with cowpox. When the boy recovered from the cowpox he was then deliberately infected with smallpox and fortunately he did not contract the disease.


Science and Technology in Action has been developed with the active participation of many of our leading science oriented organisations from the private and public sectors.

It is an innovative and attractive resource for teaching and learning that benefits both industry and education.
