Which of the following is an example of specific immunity?
zvonat [6]

Answer:

Immunity to Small Pox

When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.
