Respuesta :
A(n) vaccination exposes a person to a specific antigen preparation in order to trigger a protective specific immune response without the person suffering any effects associated with the pathogen.
In the field of immunology, vaccines can be described as weakened, attenuated, or killed microorganisms that help to induce an immune response inside an organism. As these biological substances are weakened or killed, they hence do not harm a person but help the immune system in recognizing the particular antigen.
A system through which a vaccine is administered to a person is known as vaccination. Vaccines are important because whenever that particular antigen will infect the body of a person, the antibodies will immediately recognize it and effectively produce an immune response against it.
In this way, vaccination helps to trigger a protective immune response against antigens.
