Dear Therapeutic Goods Administration,

It is of great importance to monitor the specific batch number associated with individual adverse event case reports.  It is de rigueur for quality control and is a best practice requirement world wide.

It is clear that while a particular medication may be deemed safe and batch testing completed, particular batches can still vary in important ways (such as percentage of active ingredient) and the very first indication of a problem would be the accumulation of adverse events associated with any particular batch number.

It has been demonstrated by International databases that a small percentage (As low as 5%) of batch numbers account for the majority of adverse events.

Searching the DAEN database, case numbers are provided without batch numbers.

I can't imagine you would not have collected this information as It would be incompetent in the extreme not to be monitoring such a central, significant  and vitally important safety signal.

Can you please provide this information* or point to where it is publicly available.

Specifically, please provide me with a list of batch numbers listing the case report numbers associated with each** for the period of the COVID-19 vaccination rollout to date.

*The batch or lot number associated with each individual case report number.
**I am aware that lot numbers are listed separately in the batch release assessment report online.

Yours faithfully,

Scott Bennett
