Question

How do you appreciate Edward Jenner's experiments?

Answer 1

Hint: Edward Jenner, a Gloucestershire English country doctor, is administering the first vaccine in the world as a preventive treatment for smallpox, a disease that has killed millions of people over the years.

Complete answer:
Cowpox is a rare, typically mild, disease in cattle that can be transmitted from a cow to a human through sores on the udder of the cow. Smallpox, by comparison, was a lethal human illness. About 30% of those infected were killed by it. Often, survivors bore deep, pitted scars on their faces and other body parts affected by the blistering disease. A leading cause of blindness was smallpox. Now we know that the virus which causes cowpox belongs to the virus family of Orthopox. Variola viruses, the ones that cause smallpox, are also included in Orthopoxviruses.

Smallpox has destroyed humanity for many decades. Thanks to Edward Jenner's remarkable work and later developments from his efforts, we don't have to worry about it in modern times. The historical origins of immunization are often forgotten, given the rapid pace of vaccine development in recent decades. For its groundbreaking contribution to immunization and the eventual eradication of smallpox, Edward Jenner is well recognized around the world. Despite the fact that he was neither the first to propose that cowpox infection conferred unique immunity to smallpox, nor the first to attempt cowpox inoculation for this reason, Jenner's work is widely regarded as the cornerstone of immunology.
The work of Jenner represented the first scientific effort to contain an infectious disease by using vaccination deliberately. He did not invent vaccination, strictly speaking, but was the first person to confer scientific status on the procedure and undertake its scientific investigation. Jesty used bovine udder material that he knew had cowpox and transferred the material to his wife's and two boys' arms with a small lancet.

Note:
Analysis and interpretation of data collected during the testing phase is a final step in scientific methods. This enables the researcher to form a data-based conclusion. A successful conclusion takes all the knowledge obtained into account and would focus on the hypothesis, whether or not it supports the hypothesis.
