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.
Both active and passive immunity provide protection against specific pathogens. Active immunity is developed by the body after exposure to a pathogen or through vaccination, while passive immunity is acquired through the transfer of pre-formed antibodies from another source. Both types of immunity are specific to the pathogen encountered or targeted by the antibodies.
Active immunity can be acquired through natural exposure to an infectious agent, which triggers the body's immune response to produce antibodies. It can also be acquired through vaccination, where the immune system is exposed to a weakened or inactivated form of the pathogen, leading to the production of antibodies without causing illness.
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
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.
Active Immunity - Vaccines are used for health purposes to expose our bodies to a particular antigen. These antigens are usually killed or severely weakened to decrease their potency. After destroying these pathogens, the body stores some T cells as memory cells, due to the fact they code for a particular antigen and can be when needed. This memory in T cells can be a means of artificially acquiring immunity while a genuine attack by a pathogen is a naturally acquired type of immunity. Passive Immunity - This is where immunity to particular antigens as a result of genetic traits passed on from parents rendering the offspring immune to a particular pathogenic threat.
