Thanks for the link Mso, I've seen that one before. There certainly does seem to be a lot of contradictory info about this.
For example GBS is listed on the Novartis H1N1 vaccine package insert as an "Adverse Reactions Associated with Influenza Vaccination". It is also stated that "The 1976 swine influenza vaccine was associated with an increased frequency of Guillain-Barré syndrome (GBS). Evidence for a causal relation of GBS with subsequent vaccines prepared from other influenza viruses is unclear."
The Institute of Medicine states on its website that "the evidence favored acceptance of a causal relationship between the 1976 Swine Influenza vaccine and GBS".
Now, I'm not saying that bacon sandwichs are related to twisted ankles, vaccine reactions or anything else because that, obviously, would be very very silly.
What I am saying is that here we have a relatively rare syndrome that has been associated with a certain vaccine and a teenager who has received a similar vaccine has just developed that relatively rare syndrome.
Considering that this syndrome is a documented possible side effect of this type of vaccine it seems reasonable to state that what happened to this boy is possibly a vaccine reaction. It seems, to me, less reasonable to say that his developing a documented side effect of this type of vaccine was a coincidence and more likely to be related to the bacon sandwich he ate at lunchtime.
Now we may well find out that this particular case of GBS does turn out to be a bacon sandwich reaction or due to a viral illness or similar. In the meantime it is entirely possibly that it is a vaccine reaction and it is scientifically dishonest to imply that that is not reasonable to come to this conclusion.
There has been a case in France too. The women developed GBS 6 days after H1N1 vaccination. In this article (sorry it's in French) they give some info about the US.
Thsy state that there are 5 cases of GBS following H1N1 vaccination which are being investigated in the US by the CDC.
It is also stated that Jordan McFarland (from the original link) had headaches and muscle weakness 24 hours after vaccination and that he was unable to walk one week later. (They also state that he should be able to walk again within 5 to 6 weeks.)
