Thousands of Australians are repeatedly having close brushes with coronavirus without catching it and no one can work out why.
Sydney dad Craig Jeffs has never tested positive to Covid despite having at least three close calls with the virus.
‘At the start of the pandemic, I had dinner with a work colleague and it was the very beginning,’ he told A Current Affair.
‘We shared a steak and a glass of wine and I actually had some steak off his plate. He was positive at the time.’

In another close call Mr Jeffs sat next to a Covid-positive friend for a rugby match, and then recently isolated with his wife after she contracted the virus.
Given the contagious nature of Covid, most people would expect Mr Jeffs to test positive after at least one of these exposures but he never did.
Courtney Forth, 26, works as a supermarket manager and looked after both her sick parents without ever testing positive herself.
She said she was constantly around them while they had the virus.
‘Although Dad was really sick and he was laying in bed, I’d still go and take him dinner, or take him an icy pole, or something like that and I still haven’t got it,’ she said.

Professor Bruce Thompson from the University of Melbourne said Covid research was still in the ‘very, very early’ stages but new evidence suggested a history with the flu or common cold could result in the Covid ‘immunity’.
‘There’s some good data to suggest that if you’ve actually had a common cold, which is also part of the umbrella coronavirus group, then you may be a bit more protected,’ he said.
The research found ‘high levels of pre-existing T-cells’ – which are created by the immune system to ward off the common cold and flu – could be the answer to the immunity.
However, Dr Thompson said studies on the immune system itself were still a mystery and scientific evidence has drawn no conclusion on any immunity theory yet.
