'vermitteln' and 'impfen' can both mean that someone passes on an idea, an opinion, or an attitude to others. 'vermitteln' sounds neutral and fits well when you explain something or make it understandable. 'impfen' is meant figuratively here and sounds stronger: an idea is almost impressed on someone, often over a long period of time or with a lot of influence. In everyday language, 'vermitteln' is much more common and more factual. 'impfen' fits better when you want to emphasize that an attitude is deeply anchored in someone.
