Question

in 1796, edward jenner made observations that dairymaids rarely got smallpox. smallpox was a deadly disease that caused a spotted rash that left disfiguring scars. the phrase “pretty as a milkmaid” likely originated from observations that dairymaids didnt usually get smallpox. jenner notes that dairymaids often got a similar illness that wasnt as deadly, called cowpox, because they dairymaid got it from cows. jenner proposed that cowpox was giving them an immunity to smallpox. he tested this by infecting a boy with cowpox. after the boy recovered from cowpox, jenner exposed him to smallpox. the boy didnt not get smallpox. in fact, the latin word for cow is “vaccinae” which is where we get the word vaccine from. reasoning: if cowpox grants an immunity to smallpox then... complete the sentence to illustrate how reasoning was used in the scientific discoveries. for each short story, identify the claim by highlighting green. find any evidence statements and highlight in yellow

Explanation:

Edward Jenner observed dairymaids' immunity to smallpox after getting cowpox. He tested by infecting a boy with cowpox and then exposing him to smallpox, and the boy didn't get sick. The Latin word "vaccinae" for cow is where the word vaccine comes from, showing how Jenner's reasoning led to the scientific discovery of vaccination.

Answer:

If cowpox grants an immunity to smallpox then the word vaccine comes from the Latin word "vaccinae" for cow, as demonstrated by Jenner's experiment of infecting a boy with cowpox and then exposing him to smallpox with the boy not getting sick.

Claims: Cowpox grants immunity to smallpox; Dairymaids often got a similar illness (cowpox) from cows and rarely got smallpox; The boy recovered from cowpox and didn't get smallpox after exposure.
Evidence: Jenner's observations of dairymaids; Jenner's experiment with the boy.
