Long before vaccination, communities in parts of Asia and Africa practiced forms of variolation: introducing material from a person with smallpox in hopes of causing a milder infection and later protection. The method carried serious risks, but knowledge of it traveled to other regions. Edward Jenner’s work therefore began within a longer, international history of preventing smallpox.
In England, Jenner also learned from rural observations that people who had caught cowpox seemed protected from smallpox. In 1796, he used material linked to cowpox from Sarah Nelmes in an experiment on James Phipps, his gardener’s eight-year-old son. Jenner later deliberately exposed Phipps to smallpox, and the boy did not develop the disease.
That experiment helped demonstrate a path toward vaccination, but its methods raise serious ethical concerns. An eight-year-old could not give informed consent as an adult could. Deliberately exposing a child to a potentially fatal disease would not meet current research protections.
Jenner did not end smallpox alone. Researchers, vaccine producers, governments, the World Health Organization, and local health workers built later campaigns. Vaccination was combined with case finding, surveillance, and rapid containment across many countries. In 1980, the World Health Assembly declared smallpox eradicated. The achievement joined earlier knowledge, scientific testing, public-health organization, and sustained work by many people.

Question 1 of 4
Which statement best summarizes the passage?
The answer is A: Earlier knowledge and Jenner’s experiment contributed to vaccination; eradication later required collective work.
The account connects earlier prevention practices, Jenner’s contribution and ethical problems, and the later international eradication campaign.
-
Question 2 of 4
What practice existed before Jenner’s vaccination experiment?
The answer is C: Variolation in parts of Asia and Africa
The opening paragraph describes forms of variolation practiced before vaccination.
-
Question 3 of 4
Why does the passage discuss informed consent?
The answer is B: To evaluate the experiment’s method as well as its later importance
The passage distinguishes the experiment’s contribution from whether its treatment of a child would be acceptable today.

Question 4 of 4
In the final paragraph, “eradicated” means
The answer is B: eliminated worldwide
The declaration followed coordinated work across many countries, so “eradicated” means eliminated worldwide.
