I am hoping it is a small partof the course, Beach (which in turn is only a small part of further study)
have skipped ahead a little, and the whole autism/mmr subject seems to be glossed over nicely in a "some parents think that regression may be linked to mmr. however, autism becomes apparent around that age anyway, and so it is easy to confuse the two"
having had the pleasure of seeing an OU exercise on how Wakefield/mmr was handled, and reading the easily disproved lies contained within, I doubt that any actual thought or discussion is going to be sought - just regurgitating the somewhat dubious contents of the textbook.
