SARS-CoV Infection Clinical Trial
Official title:
National Cohort Study of Effectiveness and Safety of SARS-CoV-2/COVID-19 Vaccines
National cohort study of effectiveness and safety of SARS-CoV-2 vaccines (ENFORCE is an equivalence trial to evaluate the effectiveness and safety of multiple new SARS-CoV-2 vaccines approved for use in the EU, and which are being offered at participating units. The design is an open-labelled, non-randomised, parallel group, phase IV study with historical controls. A sub-study will be embedded within this master protocol addressing basic and translational research questions requiring additional sampling of biological material (under separate participant informed consent).
First phase will enrol 10,000 persons initiating vaccination (assuming 4 vaccines). If more vaccines become available additional 2,500 persons per vaccine will be included. Subsequent phases with larger sections of the population included may be implemented. Participants will have 6 study visits and be followed for 2 years after the first vaccination, which offers the participants an extra close follow up on vaccine effectiveness. Safety data will be collected at study visits until 3 months after the first vaccination. Research samples will be collected at each study visit during the two year follow-up ;
