So, to clarify, the seasonal flu shot always contains a seasonal H1N1 strain, an H3N2 strain, and a B-type. Swine flu is also an H1N1 strain. In 2009, that strain was provided as a separate shot. Last year they just stuck it in the seasonal shot (in the US, I don't know anything about Australia). Does that make sense?
The flu shot they suspended in Australia is the seasonal shot made by Fluvax and they've only suspended it for children under 5, while strongly urging children 6-10 to get a shot from an alternative company. Adults can get the vaccine from any of the 3 companies that are making the vax. The Fluvax suspension will continue into 2011, but the Australian gov't. is still recommending the seasonal shot for all age groups - just from a different source. They suspended the Fluvax version because a surprising number of children developed fevers and fever-induced convulsions after getting the shot. The expected incidence rate is 0.1%. Children given Fluvax had an incidence rate of 1%.
The pattern of the reactions is kind of interesting and I could totally geek out talking about it. But I'll refrain. :) I feel like I'm coming off as a vaccine-apologist in this thread. I'm not trying to talk anybody into getting a flu shot. I'm just ridiculously interested in public health and diseases.
