HDR Innovation Gateway Metadata Rating: Gold

The Co-STARS study began in April 2020, with the hospital performing serological antibody testing on around 1000 of its healthcare workers. Within this cohort, healthcare workers who had confirmed cases of SARS-CoV-2 infection were intensely monitored for six months. They were routinely tested to see whether the antibody levels within their blood were maintained or decreased over time. Moreover, all recruited healthcare workers are being re-tested on a six-monthly basis.

The study is ongoing, and is expected to run until July 2026.
