Two more GP practices have been caught failing to follow national vaccine storage guidelines and dozens more are being investigated by NSW health authorities. 

A statewide vaccine storage audit was launched last month after a patient reported a GP clinic in Sydney was using out-of-date vaccines apparently stored in a household fridge.

The incident led to a public health response to track down 3000 patients and tell them to see another GP for revaccination.  

But a subsequent audit identified 44 so-called “high-risk” practices, according to Dr Vicky Sheppeard, the director of communicable diseases for NSW Health.
