Brett Wilcox mentions the Urabe strain of mumps being used in the MMR vaccine on pp 82-83 in chapter 8 of his book 'Jabbed', published by Skyhorse (paperback edition, February 2020):
Each chapter has a comprehensive list of references and because the book is still fairly recent then most of the internet references are still accessible, in so far as I've been working my way through checking them.
