The Toronto Sun has reported that 17 cases had fallen seriously ill after the H1N1 vaccines. Four of these cases came down with the dreaded but rare Guillain-Barre Syndrome.It is not clear what the relationship is between these vaccines and the earlier GSK batch that had been yanked off the shelves.
The Canadian form of the vaccine appears to be slightly different from that which has been supplied to Singapore. It is called Arepanrix, and manufactured in Alberta, Canada. The one supplied to Singapore is called Pandemrix. They are essentially the same formulation but manufactured in different locations. Apparently Arepanrix has more turbidity even though the manufacturing process is same as Pandemrix.
