How did Edward Jenner test his idea?
Edward Jenner (1749 – 1823) In 1796, he carried out his now famous experiment on eight-year-old James Phipps. Jenner inserted pus taken from a cowpox pustule and inserted it into an incision on the boy’s arm.
How did Edward Jenner discover the vaccine for smallpox?
On May 14, 1796, Jenner took fluid from a cowpox blister and scratched it into the skin of James Phipps, an eight-year-old boy. A single blister rose up on the spot, but James soon recovered. On July 1, Jenner inoculated the boy again, this time with smallpox matter, and no disease developed. The vaccine was a success.
How did Edward Jenner’s research on smallpox change the world?
Jenner, a country physician, invented vaccination with cowpox to replace the fearful dangers of inoculation with smallpox. This development resulted in immunity to smallpox and ushered in the era of preventive measures for contagious diseases (World Health News.

What good things did Edward Jenner do?
Edward Jenner was a very famous English scientist whose name has gone down in medical history. Edward Jenner was responsible for discovering the world’s first-ever vaccine and his work saved so many lives – in fact Jenner’s work is said to have saved more lives than the work of any other human!
Why did milkmaids not get smallpox?
And the milkmaids themselves were getting similar bumps on their hands and were coincidentally not getting smallpox. Milkmaids were thought to be immune to smallpox and, before long, it became known that if you too wanted to be immune, all you had to do was get exposed to “cowpox.”
Why did cowpox prevent smallpox?
After inoculation, vaccination using the cowpox virus became the primary defense against smallpox. After infection by the cowpox virus, the body (usually) gains the ability to recognize the similar smallpox virus from its antigens and is able to fight the smallpox disease much more efficiently.
