You can get passive immunity through a placenta when you are a fetus in your mothers womb or you can be injected with antibodies that have most likely been forced to grow due to somebody putting a disease in an animal such as a rabbit. Unfortunately passive immunity does not last very long because the antibodies are detached from their white blood cells which keeps them a live and also stores the antibodies in their memory so you can not become immune forever via passive immunity as it is only passive e.g. short lived/quick
Passive immunity is not obtained.
It is things like the intact barrier of the skin.
Passive immunity occurs with the transfer of active humoral immunity of ready made antibodies, from person to person, from mother to child in utero.
Injection antibodies
Through vaccines
Passive natural immunity
Natural Passive Immunity
Passive immunity occurs naturally. An example of passive immunity occur when antibodies are transferred to the fetus from the placenta during pregnancy.
Passive immunity can be given naturaly or artificially.Natural Passive Immunity can be acquired from the maternal colustrum and maternal placenta.While artificial passive immunity is given parenteraly examples are: anti tetanus serum and antivenin.
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.
Passive immunity because the antibodies pass from mother to fetus.
passive
active immunity is the immunity that is stimulated internally as a a result of antibodies entering the body. Passive is stimulated by substances from an external source
antitoxin
The three types of immunity is innate immunity, adaptive immunity, and passive immunity.
Passive immunity happens when the antibody is already given to you. For example, the antibody that can be passed from mother to child. That is a natural passive immunity. The vaccine given to you when had rabies is also an example of passive immunity because again, what is given to you is already an antibody.
Passive immunity is different from active immunity because it means that you can get it from another person and you can give it someone else. Active immunity is when you get it by yourself, not from another person, and you cannot pass it to another person.
