Another vaccine question from me!
My ds 8 had 2x single measles and rubella vaccines. 1x mumps. [Younger ds had 2x MMR].
To cover for mumps should he have MMR? If so urgent now or say wait until just before puberty [age 9 or 10?].
He doesn't like injections so MMR probably preferable to blood test to check for immunity with mumps.
Holiday most of August over seas so don't really want to do now in case of side affects.
