As Omicron case numbers and reinfections rise, could the country benefit from making a second booster shot more widely available?
The answer from one immunologist is a firm, 'no'.
At the moment people over the age of 50, the immune-compromised and healthcare, aged care and disability workers are all eligible for a second booster shot, if it's been six months since their first.
Dr Nikki Turner, Medical Director of the Immunisation Advisory Centre, explains why second booster shots aren't being given to younger people just yet.
