A person acquires active immunity when their own immune system produces antibodies in response to the presence of a pathogen. Active immunity can result from either getting the disease or being vaccinated.
By a disease in the body
Active immunity is long term protection that generally lasts 20-30 years and passive immunity is immediate protection. there are two forms, naturally acquired and artificially acquired. in active immunity the naturally acquired immunity is when you suffer from the disease then recover again. the artificially acquired way is by getting a vaccination. in passive immunity, the naturally acquired way is to receive antibodies from mother in pregnancy and breastfeeding, the artificial way is to have antibodies injected in a serum for immediate response for example when you have been bitten by a poisonous animal. note they are not vaccinated.
Natural immunity occurs through contact with a disease. There are two types of natural immunity. Actively acquired and passively acquired. Actively acquired - When the body has already experience an infection by that pathogen Passively acquired - Antibodies pass across placenta providing a newborn baby with immunity against disease. Antibodies are also present in breatsmilk. Artificial immunity develops through delibereate action such as vaccine. There are two types: Actively acquired and passively acquired Actively acquired - This is by vaccination at a suitable time in the person's life, not when they are infected. eg TB vaccine Passively acquired - The vaccine contains ready-made antibodies which provide immediate relief by destroying the antigens. This is given when the person has been infected with the antigen and has no preivous immunity eg tetanus
passive transport and active transport.
After a person has had a disease, the lymphocytes remain to produce more antibodies for that pathogen if the disease is encountered again. This is called IMMUNITY.
Cells use the energy from ATP for active transport and cell division.
active acquired immunity and passive acquired immunity
There is innate immunity (that you are born with) and acquired immunity. Acquired immunity you get when you are vaccinated or you get the disease and fight it off. The best example is that of what we call common colds. There are about 100 different viruses that cause them. This is one reason that babies and young children seem to be always be coming down with one or getting over one.

Active immunity is of two kinds: Natural active immunity: This is acquired when a pathogen enters the body and immune response occurs. This is stored by the memory cells and eliminates the pathogen for the second time as soon as it enters the body. Acquired active immunity: This artificial and it is induced through a artificial source like vaccines.
passive and active immunity
The two types of immunity are natural immunity and acquired immunity. Natural immunity is the ability for the body to fight and prevent illness on its own, acquired immunity needs the help of vaccinations or exposure.

Innate immunity (also called nonspecific or natural immunity) refers to the inborn ability of the body to resist and is genetically transmitted from one generation to the next. This immunity offers resistance to any microorganism or foreign material encountered by the host. It includes general mechanisms inherited as part of the innate structure and function of each vertebrate and acts as the first line of defense. Innate immunity lacks immunological memory, i.e., it occurs to the same extent each time a microorganism or foreign material is encountered.
Humoral Immunity- acquired immunity in which the role of circulating antibodies is predominant. Natural Immunity- the resistance of the normal animal to infection
passive and active
1. mother to fetus2. Through exposure to the antigen(virus, toxins,or cancer cells).
Active immunity is generated by your body. So you get active immunity as a result of infections or due to vaccines. Passive immunity is not generated by your body. Here the antibodies are to be supplied. Child gets the antibodies from mother. Alternately you get the antibodies via injections. The effect of active immunity is long lasting. The effect of passive immunity is short lived. So the active immunity is considered as better. The passive immunity has one advantage. It is available with immediate effect, while it takes about two to three weeks, before the effects of active immunity is available.
