History of Vaccines

Before the modern era of childhood immunization, who would have thought that it would be possible for the future generations to be able to protect their children from many serious and complicated diseases!


It started 200 years ago, in the year 1796, when a scientist named Edward Jenner introduced the smallpox vaccine. Jenner had learnt that the dairy workers in rural areas would never develop smallpox (a fatal and disfiguring disease) since they had already contracted cowpox, which has a mild effect in humans. Knowing this, Jenner took out the pus from a milkmaid’s hand infected with cowpox, scratched it on to the arm of an 8-year-old boy and 6 weeks later inoculated him with smallpox. Much to his surprise, Jenner later found that the same boy did not develop smallpox.  This vaccine was then tried on many people and it was confirmed that the vaccine prevented small pox. Thus, the small pox vaccine was invented!

Who coined the term vaccine? 


Dr. Pasteur was the one who used a vaccine to successfully prevent rabies in a boy who was bitten by a rabid dog.

Other Vaccine inventions?

Thereafter, later in the 18th century, Pasteur developed chicken cholera and anthrax vaccines and from the nineteenth century, the new era of vaccination began! From the 20th century onwards, vaccination was considered a regular practice and compulsory immunization laws were passed.

Luckily, the times have changed now! We are healthier today, thanks to the vaccines introduced many decades ago!.
