What is the difference between active immunity and passive immunity?

Answer 1

Active immunity: being infected by a live antigen (bacteria/virus) active immunity can be developed through a vacciation.

Passive immunity: due to aquiring pre-formed antibodies from another individual

Answer 2

Passive immunity is the one in which ready-made antibodies are given, so that immune system of body dont have to do any active work. In active immunity, we give substances (like vaccines which are most of the time less active disease causing agent itself) which promote antibody formation in the body. - Dr. Akash Singh

Answer 3

if you are doing a lab for mrs.o.....and you just copied and pasted this question to this website...then go to Google cause you will not find it here..

who did this I actually needed to find this answer and this is what i get who is mrs.o

the answer after an hour of looking because my computer was slow is

-passive immunity is (Immunity acquired by the transfer of antibodies from another individual)

-active immunity is (Immunity resulting from the development of antibodies in response to the presence of an antigen)

I dont know if this is exactly correct but its better than that answer.

Answer 4

Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response.
Artificially acquired active immunity can be induced by a vaccine, a substance that contains the antigen. A vaccine stimulates a primary response against the antigen without causing symptoms of the disease.
Artificially acquired passive immunity is a short-term immunization by the injection of antibodies, such as gamma globulin, that are not produced by the recipient's cells.
Naturally acquired passive immunity occurs during pregnancy, in which certain antibodies are passed from the maternal into the fetal bloodstream. Immunologic tolerance for foreign antigens can be induced experimentally by creating conditions of high-zone tolerance, i.e., by injecting large amounts of a foreign antigen into the host organism, or low-zone tolerance, i.e., injecting small amounts of foreign antigen over long periods of time
