Which of the following statements is false?
a. vaccination introduces antibodies into the body in a form that does not cause disease.
b. vaccination generates memory cells.
c. during attenuation, a virus to be included in a vaccine is made less virulent.
d. heat-killed pathogens can be injected as a vaccination against certain diseases.
e. vaccination initiates a primary immune response but does not cause disease.

The correct answer is a. Vaccination introduces antibodies into the body in a form that does not cause disease.

Explanation:

Vaccination is the type of passive immunity provided to an individual from outside. Vaccine is killed or attenuated pathogenic organisms that do not have the ability to cause disease but initiate a primary immune response in the body.

Through this primary response memory B-cells are generated which recognize the pathogen when it encounters the body next time and provide immunity to the body against that pathogen.

So vaccination does not introduce antibodies rather it introduces attenuate or killed antigens into the body that does not cause disease. Therefore the false statement is a. Vaccination introduces antibodies into the body in a form that does not cause disease.

changing it is a matter of considerable debate. some people are just lucky. they inherited genes that promote a faster metabolism and can eat more than others without gaining weight.
