<span>Doctors do not administer vaccinations to people who are too sick because (option D.) the white blood cells of sick people may not be able to efficiently handle the weakened or dead form of the pathogen.

D. He or she will show some symptoms of the disease.
A carrier of a genetic disorder who does not show symptoms is most likely to be heterozygous for the trait and able to transmit it to offspring. This particular individual has inherited a recessive allele for a genetic trait or mutation but does not display that trait or show symptoms of the disease. They are referred to as genetic carriers. The chance of two carriers having an offspring with the disease or genetic disorder is 25%
