Seroprevalence of SARS-CoV-2-specific antibodies among Australian blood donors, February–March 2022
Following initial serosurveillance activities in 2020, the Australian COVID-19 Serosurveillance Network has embarked on a program of repeat surveys of blood donors. The program aims to estimate the prevalence of antibodies to SARS-CoV-2, whether derived from vaccination or natural infection and examine variations over time using repeat cross-sectional surveys of Australian blood donors.
