B) Attenuated smallpox virus
C) Large dose of smallpox virus
D) Small dose of smallpox virus
Show Answer
Answer:
Correct Answer: A
Solution:
The correct option is A Attenuated cow’s pox virus
Vaccination is the administration of antigenic material (a vaccine) to stimulate an individual’s immune system to develop adaptive immunity to a pathogen.
Edward Jenner administered the world’s first vaccination as a preventive treatment for smallpox.
He took fluid from a cowpox blister, attenuated the cowpox virus and introduced it into the skin of James Phipps, an eight-year-old boy who is suffering from smallpox.
A single blister rose up on the spot, but James soon recovered. So, the correct answer is ‘Attenuated cow’s pox virus’.
