Answer:
A polio antigen
Explanation:
<em>The substance in the polio vaccine that makes it effective in the mitigation of the disease is the polio antigen.</em>
<u>An antigen is any substance that is capable of eliciting an immune response in an individual through the production of antibodies.</u>
Antigens could be of two types;
- foreign or hetero antigens
- self or auto antigens
Foreign antigens are those whose sources are from outside of the body while self antigens are those within the body, a characteristic of people with auto-immune diseases.
The polio vaccine contains polio antigens which is an inactivated or weakened form of the pathogen responsible for causing the polio disease.
