how contagious is 'mumps' if you've had your mmr vaccination? . i have 1 grandchild out of 11 that has developed mumps. he has had his mmr. is it safe to have him and his siblings over with the other family members?
the mmr offers good protection. but unfortunately not 100%. mumps is contagious but i do not know what stage of the illness your grandchild is in so this question needs to be addressed to the medical provider who made this diagnosis. <link>
