B. Immunization against polio
C. Vaccination against smallpox
D. Immunization against smallpox

Answer 1

Vaccination is when a vaccine in the form of a dead pathogen or inactivated pathogen is administered to a person to create immunity from that disease and the immune response created in response to the foreign particle inside the body is called immunization.

Complete answer:
Edward Jenner developed the first vaccine in the world by taking the fluid from a cowpox blister and injected it into the skin of James Phipps, an eight-year-old boy. A single blister rose up on the spot, but James soon recovered and then after inoculating the boy again, this time with smallpox matter and no disease developed. Smallpox has been eradicated now from the world. The term vaccine is derived from the Latin word for cow, illustrating the origins of smallpox vaccination and the cowpox served as a natural vaccine until the modern smallpox vaccine emerged in the 19th century and from 1958 to 1977, the World Health Organization conducted a global vaccination campaign that eradicated smallpox that is the only human disease to be eradicated. Smallpox is caused by one of the two virus variants namely Variola major and Variola minor. Its initial symptom includes fever and vomiting. and later soreness in the mouth and skin rashes.
Hence, the correct answer is option C.

Note: There are different types of smallpox vaccines like dry vac which is calf lymph in freeze-dried form and was the oldest vaccine used. Immune and ACAM-200 are the other smallpox vaccines used. It is a communicable disease that is transmitted from infected individuals and contaminated objects.
