What is Passive Immunity?
Passive immunity, in contrast to active immunity, involves the transfer of pre-formed antibodies or immune cells from an external source to an individual. The recipient’s immune system does not actively participate in the production of these immune factors.
Passive immunity is a defense mechanism that relies on the transfer of pre-formed antibodies or immune cells from an external source. It provides immediate but temporary protection against specific pathogens without the recipient’s immune system actively participating in the production of immune factors. While passive immunity does not induce long-term immune memory, it serves as a valuable short-term defense, particularly in situations where immediate protection is needed or in individuals with compromised immune systems.
Difference Between Active And Passive Immunity
Difference Between Active And Passive Immunity: Active and passive immunity are two distinct mechanisms by which our bodies defend against infections and diseases. Active immunity, as the name suggests, is a proactive response initiated by our immune system. On the other hand, passive immunity takes a different approach, relying on external sources of protection. Both active and Passive immunity helps the organism to fight the disease.
