yes, they should and women planning a pregnancy should be given a blood test to confirm whether they are immune or not, then get vaxed before TTC
(I've just posted this on another thread, but I think it is worth repeating)
Last year when I was 7 months pg with DD I worked briefly with some children at DS4's school and one of the children was confirmed being ill with measles, another suspected.
the time line we worked out meant that I was borderline in danger of having caught it - my mum was adamant I was vaxed as a kid, but blood test showed otherwise!
perhaps it didn't take and she later remembered I may have missed out because I was very ill at the time I should have had it.
we checked it online and when I was 2yrs the policy changed, so it never got done, as it wasn't compulsory anymore! (this was mid-seventies in Hungary).
so yes, bad luck and less info at the time (my mum felt terrible guilyy as well as worried).
if I had know, I would have gotten vaccinated before getting pg with eldest, but there are no routine tests for this!
measles in pg women can cause a late miscarriage or still birth, so I was terrified of loosing my DD and was furious at the thought that if that kid wasn't vaxed by choice I could potentially lose her due to something that could have been so easily avoided!
Thank God I didn't catch it, so all was fine, but those two weeks were just horrendous, I don't wish that on anyone!
