The majority of Australians have received at least two doses of a COVID vaccine — and they've most likely caught the virus as well.  New research suggests this hybrid immunity offers good protection against severe disease, although the risk of long COVID persists with even mild bouts of infection.  There could soon be a simple model to predict how likely you are to recover well from COVID, or whether you'll go on to develop post-viral symptoms.  Guest:  Professor Jeremy Nicholson Director, Australian National Phenome Centre, Health Futures Institute References: Protective effectiveness of previous SARS-CoV-2 infection and hybrid immunity against the omicron variant and severe disease: a systematic review and meta-regression A patient-centric modeling framework captures recovery from SARS-CoV-2 infection
