You need to be more specific. Do you mean the Naturally acquired active immunity process or the Artificially acquired active immunity process? Both are of the Adaptive Immunity process. There are also passive processes for each.
Your own body
I’m ask you the Question
If you mean the body is mounting an immune response to foreign antibodies, this can be a case of Type III Hypersensitivity (e.g. serum sickness).
The process at work at Mount Etna is volcanism, which should come as no surprise since Mount Etna is an active volcano. A link is provided to the Wikipedia article on this historic Italian landmark.

By definition, antibodies act against particles, proteins, microbes, and viruses. Each antibody has to be a "match" or a "fit" to work against what it is working on. So if you have had chicken pox, you made antibodies to act against it and inactivate it. If you are exposed again, you will not get it. If you get a blood transfusion it must match or your antibodies will inactive it and will cause a reaction that will hurt you. Think of all the things you have come across: different pollen from different plants, different colds, different flu (you have to get a new shot every year as it is different), different vaccines. It just goes on and on.

a vaccine is dead or weakened form of the virus you want to get immunity for. After the white blood cells fight them off, they already have the necessary antibodies to fight off stronger ones to come.
It exposes your body to a small dose of that disease which your body starts making anti bodies for. Your body then knows how to deal with that disease if it ever should come.
Yes, lupus antibodies can *come and go*. Usually antibodies remain present in the patient, but they may be more difficult to find in a blood test. It is possible to have lupus and have negative antibodies.
Own body cells.
antibodies
produce antibodies Plasma cells are antibody-manufacturing cells derived from B lymphocytes, following their activation by an antigen. They are responsible for humoral immunity - immunity conferred by antibodies present in the blood plasma. Plasma cells are capable of synthesising and secreting antibodies at a rate of 2000 molecules per second. Each cell will only synthesise and secrete one type of antibody. This antibody will bind specifically to the antigen that initially activated the precursor B lymphocyte. Plasma cells will synthesise and secrete antibody molecules over their short life span of 4 to 5 days. The secreted antibodies circulate in the blood or lymph and bind to their complementary antigen, thus marking them for destruction by other mechanisms.
herd immunity is immunizing a sufficient amount of people in a community so that if one person come in with the disease they wont cause an epidemic.
That could come under immunology?
Antibodies are continuous being produced by activated B cells in your body as a response to your constant exposure to invaders. Antibodies are proteins and synthesized like proteins. Therefore, antibodies will be produced until you die. However, antibodies against a certain type of invaders may disappear when the invaders are eliminated. The ability of the body to respond to the same invaders when they come again lies in the preservation of the B cells that produced these antibodies, not the actual antibodies themselves.
You are born with innate immunity which consists of natural barriers to infection. Acquired is developed after birth when you come into contact with antigens
One of the ways of fighting it is by ANTIBODIES! These are made up of white blood cells. When the antibodies come into contact with the bacterium, they will either burst them or consume them. When the bacteria gets burst, the fluids come out and then the bacterium is dead.
