Answer:
Option). all of the above.
Explanation:
Polio, influenza, and small pox are viral diseases caused by polio virus, pox virus, and influenza virus, respectively. If a person gets infected with polio, influenza, or small pox, there is no drugs or cure to treat these diseases.
However, these diseases can be prevented by vaccination before getting infected. Vaccination develops autoimmunity in individuals by triggering production of specific memory cells against the pathogens.
When a pathogen enters to the body, these memory cells make antibodies specific for particular pathogens and help the immune system to eliminate them.
Thus, the correct option is 'all of the above.'
