I had it at 28 weeks and am very pro-vaccine. I read up on it and there is an increasing number of cases of babies developing whooping cough in their first 8 wks of life before any other jabs given and this is why it is now considered best to be given to mum in pregnancy. Also when my mother had me and whooping cough vaccine was offered when i was a couple of months old (albeit 1982), she refused it as there was a bit of bad press about it at the time - i ended up contracting whooping cough at 8 months old and being quite seriously ill in hosp, it really is a horrific illness from what my mum told me as u do literally cough till u are choking and struggling to breathe. She really regrets listening to scaremongering and not vaccinating me x
