I was heavily pregnant last winter and declined the SF vaccine. I started showing symptoms just after Christmas and was hospitalised a few days later as I'd had D&V and was getting dehydrated. When we got there we discovered our baby had died - we declined an autopsy, as maternal blood pressure of 60/30 suggested "lack of oxygen" would be the answer, if there was an answer at all.
Our MW knew of 5 other women who'd been pregnant and had SF confirmed - all of whom had been absolutely fine. And one other lady who'd caught a different variant of flu and had also lost her baby.
There is and always will be limited information on the safety of new medicines for pregnant women and their babies - its unethical to include pregnant women in medical testing. In consequence, the only results we have tend to be from women that have a forced choice due to other circumstances (such as asthma increasing the risk of not having the vaccine). In an ideal world we'd have data on plenty of pregnancies and be able to do an analysis on any impact identified after 1, 5, 10, 20 years - but that will never be possible for a disease that is new.
I do not believe we have an accurate picture of how widespread the SF outbreak was last winter, as the symptoms I showed did not match those publicised at the time even though I was swabbed and tested +ve. I do think that SF affected a disproportionately large number of young adults when compared to other flu variants - but without having accurate data on the number of SF cases that will be impossible to establish. I do believe that, in general, SF turned out to be a lot milder than was feared - possibly adding to the lack of official diagnosis and further confusing the actual data, and certainly adding weight to the argument that it was never a problem and vaccination was a complete waste of time.
This page from the NHS has been updated in the last couple of weeks. From what I can gather;
- SF was a pandemic (as it was a virus that spread around the globe), although the WHO have announced it to be over
- SF was much milder than feared
- all pregnant women are still recommended to have the SF vaccine, either as a SF vaccine or as 2010/2011 seasonal flu vaccine (which will include H1N1)
If you want to try and make a reasoned decision you have to try and do a risk/consequence assessment of how likely you think you are to catch SF and have complications vs. how likely your baby is to suffer side effects from the vaccine, whilst factoring in the knowledge that the vaccine isn't 100% effective (ie even if you have it you may still catch SF and develop complications). From what I can gather there is insufficient evidence to quantify either set of risks so it really is impossible to make an informed decision. Even given what happened I still can't say, hand on heart, that if I could do it all again, I'd have the jab.
At the end of the day, all you can do is make the decision that you feel most comfortable with and then try not to revisit it.
