My daughter had whooping cough 4 1/2 years ago when i was pregnant with ds1. She wasn't allowed the vaccination when she was due it, and nor was I as a child. She saw 6 different doctors before someone realised what it was, and that was only due to the fact that he had worked abroad a lot and seen so much of it there. Doctors over here knew v little about it, and couldn't even tell me if I was at risk of passing it to ds1 while he was inside me, as I hadn't been vaccinated either.
She caught it in August, and it finally went enough for her to return to school in January.We spent night after night with her watching her face turn purple from coughing so hard and unable to draw breath, finally vomiting from the force of it. I didn't think someone could cough so hard and for so long without something bursting, honestly it was really really distressing for her and me. If I ever doubted about whether or not to give the vaccine to my others then this changed my mind. She couldn't attend school, couldn't eat properly, sleep properly, her chest hurt, her throat was sore, she was terrified each time a bout started, which made it worse by panicking. The school was a complete a**e about it,when I made a fuss about the lack of help in trying to get her back to school they had a fit. I said I wasn't going to send her in if they wouldn't help her in a coughing fit ( she was no longer contagious after about 3 months of having it) so they threatened to prosecute me! I ended up getting a physiotherapist to see her to sign her off school until the new year, and she gave her some breathing exercises to do when she started a spate of coughing, to help her get it under control again.
Eventually these worked and she was able to go back to school, but it was something I would never want anyone to go through.
Interestingly enough on finding a doctor who knew about whooping cough,they said the vaccination either works completely or not at all ,so even if she had been done, she could still have caught it.
Ds1 was born during this time and fortunately he was ok, but it didn't help my stress levels worrying about it at the time.
