Simplified etymology

Immune comes from Latin immunis, “exempt from public service,” literally “not ready for service.” From the 15th through the 17th century it generally meant “free from a liability”; the biological sense “able to resist infection” dates from the mid-19th century.

From Middle English, from Middle French immun, from Latin immūnis (“exempt from public service”), from in- (“not”) + mūnus (“service”).
