Dictionary definition of immunity

The state or condition of being immune, which implies having a heightened resistance or protection against a particular disease, infection, or harmful substance.
"A strong immune system is essential for maintaining overall health and well-being."

Detailed meaning of immunity

It is the ability of an organism, such as a human or animal, to defend itself against pathogens or toxins and prevent their detrimental effects. Immunity is a complex biological process involving the immune system, which consists of various specialized cells, tissues, and organs. When the immune system recognizes a foreign invader, such as a virus or bacteria, it mounts a response to neutralize or destroy the threat. Immunity can be acquired naturally through previous exposure to a pathogen, resulting in the development of antibodies and memory cells that provide long-term protection. It can also be obtained artificially through vaccination, where a weakened or inactivated form of the pathogen is introduced to stimulate an immune response without causing illness. Immunity plays a crucial role in maintaining overall health and well-being by safeguarding the body against harmful agents and promoting resilience in the face of potential threats.

History and etymology of immunity

The noun 'immunity' is derived from the same Latin root as the adjective 'immune.' It originates from the Latin word 'immunitas,' which combines 'in' (meaning 'not') and 'munus' (meaning 'obligation' or 'duty'). In ancient Rome, 'immunitas' referred to the exemption from certain civic duties or obligations, often granted as a special privilege. Over time, the term expanded to encompass the concept of protection from diseases, infections, or harmful substances. 'Immunity' thus denotes the state or condition of being immune, implying a heightened resistance or protection against specific diseases, infections, or harmful agents. The etymology of 'immunity' highlights the idea of exemption or protection, underlining the role of our immune system in safeguarding the body against health threats.
