cantpissinpeace, what do you mean that you have no responsibility to random pregnant women? What you are saying is, I don't give a shit about the rest of society as long as me and mine are okay.
I'll add to this with a story from when my mother was pregnant with me, before there was a rubella vaccine.
My mum went to visit her cousin not long after she found out she was pregnant (mum's pregnancy not cousin). My cousin had a toddler the same age as my older brother and they obviously played together, both sat on the knees of their own mothers and their 'aunties' knee. A fun family time with tea and biscuits and orange squash for the children.
A couple of days later the cousin's child was ill and taken to the Dr who diagnosed German measles (as it was called then).
The cousin burst into tears, not because of her daughter but because of what may happen to my mother's pregnancy, the very real risk that I could be born deaf and blind with heart defects and autism.
Also my brother could have caught the disease causing a further exposure for my mother and I.
My mother's only option was gamma globulin injections, these are blood products so there is a risk of hepatitis and other blood born disease.
In 1996 there was an outbreak of rubella in the UK, 12 children were born with 'congenial rubella syndrome'.
12 children disabled by the selfish actions of people like you cantpissinpeace.
12 children with lives made immeasurably harder, 12 families changed for ever.
