Poor communication and complex reporting systems for adverse events post vaccination led to a slow response of government officials when it came to withdrawal of the seasonal flu vaccine for children under five. An independent review into the flu crisis found that only limited clinical trials (low 100s) were performed in children aged between 6 months and 3 years of age. The number of participants in the clinical trial was about average for the seasonal flu vaccine however it is very difficult to find any data from the TGA website as to whether an increased risk of febrile convulsions was observed in this trial. By April the number of febrile convulsions believed to be triggered from Fluvax had been reported at 9 per 1000 children, up form one per 1000. The review ordered by Health Minister Kim Hames suggested that the reporting process was confusing and did not allow for quick collation of data on events such as these.
