PHE’s ‘SIREN’ (SARS-CoV-2 Immunity & REinfection EvaluatioN) study has studied volunteer health workers from across the NHS in order to establish the extent and duration of protection conveyed by naturally-acquired immunity as a result of COVID-19 infection.
Journalists dialled in to this briefing to hear from the study investigators as they present the first set of results from this study, and answer some of their questions.
Please note this data is a preprint, so it has not yet been through peer-review and is not published in a journal.
