The interaction between Taunt and Immune is similar to the interaction of Taunt and Stealth. If a Taunt minion possesses either of these other keywords, it stops working until that keyword is removed.

These interactions have been in Hearthstone since the start, but Immune as a Keyword in the collectible set is quite rare and typically doesn’t last more than a turn.
