But Prof Cunningham said there was some good news, thanks to T-cells, the likelihood of severe disease when reinfected with Omicron was much lower. Professor Catherine Bennett, Epidemiology chair at Deakin University, explained on ABC TV that reinfection was how Omicron was discovered. The research showed that antibodies developed during the first wave had reduced effectiveness against six variants, including those observed in the second wave in Australia, as well as three variants of concern that had driven the global pandemic in the UK, Brazil and South Africa.
He explained this is why it was so important for immunocompromised people to get their four doses of the vaccine.“There’s a particular type of leukaemia where people are being treated with immunosuppressant drugs where it’s incredibly difficult to get them to develop antibodies and they may even be treated with antibodies themselves – in other words they’re given people’s antibodies not their own.
