How Do You Spell PASSIVE IMMUNITY?

1. Passive immunity refers to the temporary protection against a specific pathogen or toxin that is acquired via the transfer of pre-formed antibodies or immune cells from one individual to another. This type of immunity does not involve the individual's own immune response but rather relies on the borrowed immune components to provide immediate defense against the attacking agent.

   The transfer of immunity can occur naturally, through the passage of antibodies from a mother to her fetus through the placenta or through the transfer of antibodies in breast milk. Artificially acquired passive immunity can be achieved through the administration of immune components such as monoclonal antibodies, antitoxins, or immune globulins, derived from humans or animals previously exposed to the pathogen. These immune components may be injected into the bloodstream or given orally.

   Passive immunity provides immediate protection against infections or toxins but is temporary because the borrowed immune components eventually degrade within the body. Unlike active immunity, which involves the stimulation of the individual's own immune system to generate long-lasting protection, passive immunity offers immediate but short-lived defense. This type of immunity is particularly useful in emergency situations where time is limited, or in individuals who are unable to mount an effective immune response of their own, such as those with compromised immune systems or newborns.
