It is also suitable for people with immune system deficiencies. Artificial passive immunity comes from injected antibodies created within a different person or an animal. Passive immunity gives temporary protection by transfer of certain immune substances from resistant individuals. Passive immunity is that derived from the delivery of pre-formed antibodies into the calf and provide short-term protection. Examples of passive immunity in the following topics: Passive Immunization. This transfer only occurs during the first few hours following birth. Immunity is the ability of a body to guard itself against diseases. 2. Active immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. These antibody-containing preparations are termed antiserum. Almost all vaccines exert an effect via active immunisation. That is a natural passive immunity.

Since the recipient’s immune system is not involved in this process and transfer of antibodies taking place quite naturally it is referred as “natural acquired passive immunity”. A prominent difference between active and passive immunity is that active immunity is developed due to the production of antibodies in one’s own body, while passive immunity is developed by antibodies that are produced outside and then introduced into the body. This is the first line of defense against any microbial attacks on the baby. Examples include TAT, DAT, and HBAT. For example, the antibody that can be passed from mother to child. Active Immunity .

Active immunisation is when the immune system is primed to form antibodies against a specific pathogen. However, unlike active immunity… Certain pathogens cause disease by secreting an exotoxin: these include tetanus, diphtheria, botulism and cholera—in addition, some infections, for example pertussis, appear to be partly toxin mediated [3,4].In tetanus, the principal toxin (termed tetanospasmin) binds to specific membrane receptors located only on pre-synaptic motor nerve cells.
