The local medicines authority here insists on conducting their own data review before they approve any vaccine for local use despite competent authority approvals overseas. Why?
The local medical authorities in the UK and US have given emergency 'approval' for the use of couple of vaccines because their situation is critical and bordering on unmanageable. Ours is not.
Some months ago most medical authorities around the world, including here, suggested that the complete results of testing of a number of the vaccines would be complete in March. I guess it was on that basis that the Australian Government set it's timeline.
