The first and foremost difference between active immunity and passive immunity is that active immunity is being produced for the contact with pathogen or the antigen, whereas passive immunity is being produced for the antibodies that are obtained from outside. It eventually helps in the successful reduction of symptoms for diseases include immune suppression. The maternal passive immunity can be referred to as the kind of naturally acquired passive immunity, which subsequently refers to an antibody-mediated immunity conveyed to the foetus by the respective mother.

Active immunity can be defined as the immunity, which develops only after major expose to any disease caused contagious microorganism as well as the other foreign substances like following proper vaccination and infection. The fourth difference between these two immunities is that the antibodies are being produced by the human body as per response to the antigen or pathogen, whereas in passive immunity, these distinctive antibodies are being gained from the inside body. For human beings, MatAb or maternal antibody is being passed on through placenta to infant or foetus through the receptor of FcRn over the cells of placenta. Immunity can be defined as the capability of a human body for destroying pathogens as well as any other foreign particles and even for preventing a further case of any kind of infectious disease.

This kind of immunity could take place naturally, for example when a newborn baby is receiving the antibodies from his or her mother by breast milk or placenta; or it could even occur artificially, for example when any specific person is receiving these antibodies within the form of an injection like gamma globulin injections. Active immunity … In the case of passive immunity, protection is immediate. The immunity that is being derived from the passive immunization majorly lasts for only a few weeks to almost 3 to 4 months/ There also exists a major threat for the hypersensitivity reactions such as gamma reactions. This can be done through breast milk or via an infusion. On the other hand, passive immunity is when an individual receives lymphocytes and antibodies produced from the immune system of another individual. Active immunity requires an individual to be exposed to the pathogen or antigen, but passive immunity … Let's take a closer look at active and passive immunity and the differences between them. All rights reserved. It is also termed as the most utilized antibody of more than 5 kinds of antibodies that are found within the body.

Active immunity is induced by microbial infection or by contact with antigens. It needs to be presented before it is recognized. Passive Immunity Active immunity is the type of adaptive immunity that comes in direct contact with the pathogens, antigens or the foreign harmful elements, whereas passive immunity is the type of adaptive immunity that does not need to be in direct contact with the bacteria, pathogen or any other harmful foreign elements.
