Which statement best describes what will most likely happen when an individual receives a vaccination containing a weakened pathogen?
A
The ability to fight disease will increase due to antibodies received from the pathogen.
B
The ability to fight disease caused by the pathogen will increase due to antibody production.
C
The ability to produce antibodies will decrease after the vaccination.
D
The ability to resist most types of diseases will increase.
Explanation: 

Detailed explanation-1: -When you get a vaccine, your immune system responds to the vaccine the same way it would to the real germ. It: Recognizes the germ in the vaccine as being foreign. Responds by making antibodies to the germ in the vaccine, just as it would for the real germ.

Detailed explanation-2: -Active Immunity Vaccine-induced immunity is acquired through the introduction of a killed or weakened form of the disease organism through vaccination.

Detailed explanation-3: -This is called an antigen. When a person gets a vaccine, their immune system recognises the antigen as foreign. This activates the immune cells so that they kill the disease-causing virus or bacterium and make antibodies against it.

Detailed explanation-4: -Adaptive immune responses are the basis for effective immunization against infectious diseases. The cells of the adaptive immune system include: antigen-specific T cells, which are activated to proliferate through the action of APCs, and B cells which differentiate into plasma cells to produce antibodies.
