Etymology
The word 'immunized' traces its lineage to the Latin legal term 'immunis', meaning "exempt from public service or burden," formed from the prefix 'in-' (not) and 'munis' (service, duty). This concept of exemption was metaphorically extended into the biological realm in the 19th century to describe the body's exemption from disease. The suffix '-ize', of Greek origin, was added to form the verb 'immunize', meaning "to render exempt," and the past participle '-ed' creates the adjective describing the resultant state. Thus, the modern medical meaning logically evolves from the ancient idea of being freed from a common obligation or threat.
