Adaptive Immune Response

The body's immune system's ability to recognize and specifically react to pathogens through the activation of lymphocytes, providing long-lasting protection.

Active Immunity

Immunity that develops as a result of exposure to antigens; it can occur naturally after recovery from a disease or can be artificially induced by immunization with a vaccine. Compare with passive immunity.

Passive Immunity

Temporary immunity that depends on the presence of immunoglobulins produced by another organism. Compare with active immunity.
