my friend had the vaccine when she was young like everybody .As an adult, she went to mexico on vacation... she didn't know she was 3 weeks pregnant at the time and she went to a house where a little girl had rubela... when she came back and found out she was expecting, she told her doctor right away and he ran some blood tests to see if she had been immunized, he found that she did have the antibodies so he said not to worry.
Her son was born with a small head, lung problems, blind, deaf and with a mental capacity that will never exceed the age of 6 or 7 years old. He's very handicapped. Turns out she was not immuned to that particular strain of the virus (different strain than the one she had been immune to)
she since has given birth to 2 other kids that are perfectly healthy
I'm thinking they can treat her for the virus now that she has miscarried and she will get a vaccination too. You have to wait 3 months after the vaccine before you can get pregnant. I found out that I was not immuned to it, even though I had been vaccinated twice as a child. So, when I had my last miscarriage (not because of the virus), I got the vaccination since we went to a RE and were running all kinds of tests and we knew we wouldn't be getting pregnant before the 3 month period anyway.
