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>

The polio vaccine contains polio antigens which is an inactivated or weakened form of the pathogen responsible for causing the polio disease.
Somebody needs at least one XC to not be colorblind. XcY doesn't have XC, so they are colorblind. XcXC has XC, so they are not colorblind. (a colorblind female would need both to be colorblind - XcXc)
And XcXC female can pass colorblindless onto her children. For example, even if the father was a normal male (XCY), the one possible child could be XcY (with Xc from the mother and Y from the father), which doesn't have XC so its colorblind.
