Other Words from immune

immune noun

Is it immune from or immune to?

Many people find themselves confused about which preposition, to or from, to use after the word immune. The traditional wisdom of usage commentators is that you become immune to a disease or a drug (such as HIV or antibiotics) but immune from an obligation (such as a taxation) or something that can happen to you (such as prosecution). But some say that the choice of preposition depends on the relationship between the affecting thing and the object being affected. According to Bryan Garner in Modern English Usage, for example, “What you’re immune from can’t touch you; what you’re immune to may touch you, but it has no effect.” So if you are immune from prosecution, the prosecutor cannot go after you; if you are immune to a suitor’s charms, the suitor can keep wooing you, but it would be to no avail.

Actual usage shows that there are no perfectly clear-cut rules. One can, for example, be immune to legal consequences or be immune from typhoid. The best advice, then, might be to follow your own ear.
