As Omicron surges and COVID records fall, will we have to close borders again and increase restrictions?

ABC  

Australia is on the brink of an identity crisis as our highly vaccinated, low-COVID nation faces its most significant confrontation yet with SARS-CoV-2. For Deakin University's chair of epidemiology, Professor Catherine Bennett, the wisdom of open borders has a straightforward answer: "If not now, when?" The decision to open borders in February all but guarantees months without COVID are drawing to a close and Hamilton believes Western Australians will "regret opening up". While anecdotal evidence to date is comforting – showing rising Omicron infections in South Africa are not showing an equivalent rise in hospital admissions — Professor Fiona Russell from the University of Melbourne points out that understanding how severe Omicron will be in different age groups and greater understanding of vaccine effectiveness is "critical" to charting the path forward. "There's a different arm of the immune system called T cells and even if your antibody levels go down to zero, it doesn't, doesn't mean you're not protected," says Professor Russell from University of Melbourne.
