6. “Working Group concluded that the data are adequate to assess the presence or absence of a signal. Additionally, the Working Group concluded that the data do not favor a signal between the outcomes examined and the H1N1 vaccines. A signal is defined as an event that could be temporally occurring more often after vaccine receipt than anticipated by chance alone.” Report Conclusions
