Mumps went around when I was in the 5th grade but I never caught it................
I remember having all those “childhood” diseases.
I was born after 1957 and was told that I could not have had MMR because of the vaccines they had started giving.
I convinced them to draw tigers to check and sure enough, both IgG and IgM antibodies were high. (IgG is the titer that is elevated when you’ve been vaccinated, IgM is elevated if you’ve had the illness)
The doc that said that I could not have had the diseases informed me that “ wow, you had all those illnesses”.
I just looked at him with an l told you so look.
My sister had the mumps when she was in HS. She had no trouble conceiving.
