The federal Health Department's Technical Advisory Group on Immunisation (TAGI) is heading the investigation. Chairman Terry Nolan said last night that the Australian Childhood Immunisation Register was not up to date and added, We still have concerns about the accuracy of the data. He expressed doubts regarding the inclusion of swine flu vaccine in the seasonal flu as the cause for such reactions. CSL, a Melbourne based pharmaceutical company that made the flu shots denied that the particular batch was responsible for the reactions. A spokesman said this Tuesday, CSL is continuing to work with the Therapeutic Goods Administration (TGA) and WA Health to urgently investigate the adverse event reports What we have been able to analyze so far indicates that it is not batch related...our evidence shows it was not a bad batch.

At present vaccination techniques is also scrutinized for clues. The Australian Medical Association (AMA) has also urged more details of vaccination and adverse events from SA Health. The data collated at the TGS might shed some light. AMA South Australian president Andrew Lavender feels, The medical community believes there should be nothing to hide, so why give that perception? I think the more information we can put out there with the public and with the medical profession, I think the more informed discussion we can have .But in the absence of information then I think we're going to end up with some confusing and possibly some downright wrong speculation. The public needs to know and the medical profession needs to know so that parents who are concerned about vaccination can be given adequate information to make informed decisions.
