Key Concepts

Passive Immunity

Passive immunity refers to the process by which an individual is given pre-made antibodies rather than producing them through their own immune response. This type of immunity provides immediate protection against pathogens but is typically temporary because the body’s own immune system is not actively producing the antibodies or establishing immunological memory.

Natural Passive Immunity

Natural passive immunity is acquired when antibodies are transferred from one individual to another through natural biological processes. This commonly occurs during pregnancy, where maternal antibodies cross the placenta, or through breastfeeding, where antibodies are passed in the colostrum and milk, offering the newborn early protection against infections.

Maternal Antibody Transfer

Maternal antibody transfer is the mechanism by which a mother’s antibodies are passed to her offspring. This process occurs naturally during pregnancy and through breastfeeding, providing the newborn with protection against pathogens during the early stages of life until its own immune system has matured enough to respond effectively.
