In Europe several years after the H1N1 Pandemic, it was found that people who had received the vaccine for it were contracting narcolepsy, especially children[1].
Research[2] into it has been unable to determine the exact cause[3], but the conclusion of the CDC is still "An increased risk of narcolepsy was found following vaccination with Pandemrix, a monovalent 2009 H1N1 influenza vaccine that was used in several European countries during the H1N1 influenza pandemic".

Sure - that's true of any source though, including those links you just posted. I included the podcast link because it was informative and the experts are trustworthy, whether you agree with that is up to you.
You're completely right about there being risk albeit small - but it's important to weigh up the risk on both sides which is why I think FDA emergency approval is important.
Some key points i) we have more data on these vaccines than any other in history ii) though we don't have long term data, there has never in the history of vaccines been side effects that wouldn't be detectable at this stage iii) the FDA is really dragging its feet and should have given approval by June, latest. Vaccine companies have submitted all the data for review a long time ago and previous FDA commissioners generally agree it's taking far too long. The current FDA commissioner said approval will take until January next year!
