Edward Jenner Inoculates his Own Son –  Edward Jenner

Scientist Edward Jenner (1749-1823). Small-pox, once a dreadful disease has become extinct now, with the result that vaccination against small-pox has been abandoned.

But the efforts of great people like Scientist Edward Jenner remain immortal. During his time many died of small-pox; few who survived became either blind or disfigured.

Distressed at the horror, Scientist Edward Jenner, launched a drive to protect people against this scourge.

Nucleus of thought of Scientist Edward Jenner pursuit

Cow-pox is an infection caused by the Vaccinia virus; it is similar to small-pox.

There was a local belief that if once a person contracted cow-pox, usually caused due to the sores of cow’s udders while milking, he will not contract small-pox.

Cow-pox is a mild disease in which sores appear on the fingers and hands.

So Scientist Jenner decided to put this belief to test.

On May 14, 1796 he inoculated an eight-year-old boy, James Phipps with the fluid from the cow-pox vesicles from the hands of a dairy maid.

The boy developed mild attack of cow-pox. On July 1 he inoculated the boy with the fluid obtained from the vesicles of a man suffering from small-pox, amidst all opposition.

To everyone’s surprise, the boy did not develop small-pox, i.e., he became immune to small pox.

Subsequently, Scientist Jenner inoculated his own son, Robert with the small-pox virus. That’s how Jenner had sown the seed of the theory of vaccination to control infectious diseases.

Scientist Jenner’s fame spread world-wide. Napoleon became an enthusiastic patron of vaccination.

The clergyman in Holland, Switzerland, medical men in Russia — all favoured vaccination for the people, especially children.

Present status

Immunization is achieved through vaccination. By this process, the defense mechanism of the body is strengthened.

EPI (Expanded Programme of Immunization) started in 1970 by the Government of India as a part of the National Health Policy, intended to control six vaccine – preventable diseases, viz., polio, diphtheria, pertussis (whooping cough), tetanus, tuberculosis and measles [pdpttm].

Vaccination against Hepatitis B has been included, of late.

It is hoped that polio will be completely eradicated in the world in the near future.
