When an animal receives a vaccine, about how long will it take before the animal's immune system will protect the animal from disease? a. two weeks b. two days c. two months d. two hours

The vaccinations triggers the active immunity in the organisms. The active immunity can be defined as the immunity when the immune system of the organism works to produce antibodies against the encountered antigen. Through the vaccination, the organism is given weakened antigens, which triggers the immune system to secrete antibody against it. This encounter to the antigen and release of the antibodies provides lifelong immunization to that particular antigen. After the vaccination is given, it takes almost two weeks for the animal to produce immunity against it.

The answer is option A.

Explanation:

The immunizations triggers the dynamic invulnerability in the living beings. The dynamic in susceptibility can be characterized as the resistance when the safe arrangement of the life form attempts to create antibodies against the experienced antigen. Through the immunization, the living being is given debilitated antigens, which triggers the insusceptible framework to emit immunize against it. This experience to the antigen and arrival of the antibodies gives deep rooted vaccination to that specific antigen. After the inoculation is given, it takes very nearly two weeks for the creature to deliver invulnerability against it.
