उत्तर
The vaccination against small pox means the introduction of weakened germs.
Explanation:
The vaccination against small pox involves the introduction of weakened or attenuated germs of a related virus (cowpox virus) to stimulate the body’s immune system to develop immunity without causing the disease itself. This principle was first demonstrated by Edward Jenner using cowpox to protect against small pox, which led to the development of vaccines based on weakened or attenuated organisms.
