Sometimes a study comes along that shows some amazing results and one published in The Lancet does just that.

The study - which looked at people aged between 30 and 85 who were overweight or had obesity - has found a "globally available, low-cost, and safe" diabetes drug called metformin could drastically reduce the instances of long COVID by 40 per cent.

Sadly they didn't find the same results with ivermectin (and they looked).

So what could be going on? How could this old drug be so good at what it's doing? And how could this drug be used to help bring down long COVID cases?

That's on this week's Coronacast - along with a clarification of NSW hospital data and antiviral prescriptions.
