Textbook Question
Chapter 15, Problem 8MCQ
The earliest smallpox vaccines were infected tissue rubbed into the skin of a healthy person. The recipient of such a vaccine usually developed a mild case of smallpox, recovered, and was immune thereafter. What is the most likely reason this vaccine did not kill more people?
- a. Skin is the wrong portal of entry for smallpox.
- b. The vaccine consisted of a mild form of the virus.
- c. Smallpox is normally transmitted by skin-to-skin contact.
- d. Smallpox is a virus.
- e. The virus mutated.

Students have asked these similar questions
Why was it so interesting that the woman had lesions inside of her body, and not just on the outside?
A.
Scientists never knew that lesions could form inside the human body.
B.
Lesions are only found inside the bodies of individuals who had very severe smallpox.
C.
None of these are correct.
D.
It had never been documented before that smallpox lesions were present inside the bodies of those who were severely infected.
Why is smallpox so dangerous?
A.
It has killed more people in human history than any other disease that we know of.
B.
It's transmitted by aerosol droplets and is therefore very contagious.
C.
Transmission rates are around 60%, which is higher than Ebola.
D.
All of the above
