Some preliminary studies have seen a strong correlation (like, double the expected infection rate). They don't know at this point if it's actually causation, or even whether the numbers will hold up - that's why I said "there's a chance that it might." But why take the risk? It's enough for the public health authorities in three Canadian provinces to put their seasonal flu vaccinations on hold until there's adequate H1N1 vaccine.
