Question

9. Which statement best describes what will most likely happen when an individual receives a

vaccination containing a weakened pathogen?
(1) The ability to fight disease will increase due to antibodies received from the pathogen.
(2) The ability to fight disease caused by the pathogen will increase due to antibody production.
(3) The ability to produce antibodies will decrease after the vaccination.
(4) The ability to resist most types of diseases will increase.

Answer 1

It should be 2. Bc.

Answer 2

Option (2) is the best statement that describes what will most likely happen when an individual receives a vaccination containing a weakened pathogen. The weakened pathogen triggers the body's immune response, leading to the production of antibodies that will recognize and attack the pathogen if the individual is exposed to it in the future. This creates immunity to the pathogen and enhances the body's ability to fight against the disease caused by the pathogen.
