Vaccines have side effects. The side effects of mumps monovalent vaccines are well documented. Wakefield claimed there aren't any (to promote singles over MMR) - I think he is lying, but of course, there is always the possibility that he doesn't know his stuff.
Wakefield lives in a HUGE multimillion dollar house in Texas (briandeer.com/solved/images/slapp-introduction-house.jpg). He has a 900 square foot bedroom, 6 bathrooms, a gym, a pool, 5 acres of land (which, granted, would probably cost less in Texas than in the UK). In any case, for a man who "has lost so much", he is doing very very well, I'd say.
