A member asked:

Is it possible to contract mumps if you have had the mmr jab?

A doctor has provided 1 answer

Yes: Post licensing studies show the effectiveness of a single dose of mumps vaccine at 80% while 2 doses bring the total to 88-95%.There is some suggestion that vaccine induced immunity might weaken over time in a minority of individuals.Repeated doses can boost immunity at any age and do not harm those receiving the vaccine.
