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.
