Question

Who discovered the smallpox vaccine?
A) Louis Pasteur
B) Selman Waksman
C) Cesar Milstein
D) Edward Jenner

Answer 1

Hint: The smallpox vaccine is the only solution to prevent smallpox. The vaccine is formed from a virus either weakened or attenuated, which is introduced into the blood.

Complete Answer:
1) Pasteur was a French biologist, microbiologist, and chemist who was famous for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is honoured for his remarkable breakthroughs within the causes and prevention of diseases, and his discoveries have saved many lives since then.
2) Selman Abraham Waksman was a Ukrainian-born Jewish-American inventor, biochemist and microbiologist who researched and studied the decomposition of organisms that sleep in soil enabled the invention of streptomycin and a number of other antibiotics.
3) César Milstein, CH, FRS was an Argentine biochemist in the field of antibody research. Milstein won the Nobel Prize in Physiology or Medicine in 1984 and shared it with Niels Kaj Jerne and Georges J. F. Köhler for developing the hybridoma technique for the assembly of monoclonal antibodies.
4) Edward Jenner found that vaccination with cowpox can protect individuals from smallpox. Edward Jenner is famous for his contribution to immunization and the eradication of smallpox. Jenner’s work is widely considered the inspiration of immunology and referred to as the father of immunology.

Thus, the correct answer is option D (Edward Jenner).

Additional information: The smallpox vaccine, introduced by Jenner in 1796, was the primary successful vaccine to be developed. He noticed that milkmaids who previously had caught cowpox didn’t catch smallpox and also showed that inoculated vaccinia protected against inoculated smallpox virus .

Note: The smallpox vaccine is no longer available to the public. In 1972, routine smallpox vaccination in the United States ended and in 1980, the World Health Organization (WHO) declared that smallpox was eliminated. Because of this, the public doesn’t need protection from the disease.
