Yes, some jumpers are knitted with wool which has the lanolin left in. E.G. I used to spin direct from the fleece and my wife knitted me jumpers from the wool. The wool was washed gently and a lot of lanolin was left in. It helped to make the woolies waterproof.
I used to treat the chamois liners of my cycling trousers with neat lanolin so I know I'm not allergic to it.
