Immunity obtained either from the development of antibodies in response to exposure to an antigen, as from vaccination or an attack of an infectious disease, or from the transmission of antibodies, as from mother to fetus through the placenta or the injection of antiserum. Results in resistance to further infection.
immunity to a particular disease that is not innate but has been acquired during life; immunity can be acquired by the development of antibodies after an attack of an infectious disease or by a pregnant mother passing antibodies through the placenta to a fetus or by vaccination
is gaining the ability to prevent a particular infection. Immunity can be acquired by receiving a vaccination, or getting a disease once and then the body's immune system prevents further infection to that disease.
A form of cellular defense, which identifies certain foreign substances (antigens) as harmful to the body. For this reason, the body can acquire resistance to a particular foreign agent.
Specific antibodies obtained during the life of an individual.
Immunity resulting from prior exposure to a pathogen or vaccine. This immunity is characterized by memory, specificity for a single pathogen or foreign protein and an accelerated secondary response. Acquired immunity is also called active immunity or adaptive immunity and can be divided into two responses: cellular immunity and humoral immunity
