TGA On Monday 24 May 2021, the TGA approved an application from Pfizer Australia Pty Ltd to change its current storage conditions for its COVID-19 vaccine, COMIRNATY TM. The TGA received the application on Thursday May 20, 2021. This change extends the approved storage period of the unopened thawed vial at 2-8°C (i.e. in a normal refrigerator after taking out of deep-freeze conditions) at the point of use from five days up to one month (31 days). The changed storage requirements will enable much greater flexibility in the distribution of the vaccine and have a significant impact on the roll out of the vaccine across Australia.
