I never heard of this until my OB appt. yesterday, but apparently 20-30% of women lose their immunity to Rubella when the vaccine they received as a child wears off. Unfortunately, I am one of the 20-30%.
Any one else? If so, are you concerned?
I wouldn't be concerned, but the preschool that I work in doesn't strictly enforce the MMR vaccination. So there are a handful of children who haven't had the vaccine in my school.
On a side note, I can't believe I wasn't aware of this until now. Why didn't my OBGYN say anything when I mentioned we were TTC, or when I went to the doctor regarding my m/c last fall? It would have been helpful to have been tested prior to getting pregnant!
