Brief Summary:

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).


Condition or disease Intervention/treatment Phase
SARS-CoV Infection Biological: COMIRNATY - BioNTech Manufacturing GmbH Biological: COVID-19 Vaccine Moderna dispersion for injection - MODERNA BIOTECH Biological: COVID-19 Vaccine AstraZeneca suspension for injection Phase 4

Detailed Description:

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

Primary Outcome Measures :
  1. Assessment of the effectiveness of citizens being vaccinated with one of the SARS-CoV-2 vaccines [ Time Frame: The change from Base-line in MPNAT measured via profiling of antibodies against SARS-CoV-2 Spike epitopes at 24 month ]
    Primary outcome is the minimal protective neutralising antibody titre (MPNAT); i.e. the minimum level of neutralising antibodies sufficient to protect the person from becoming infected.


Secondary Outcome Measures :
  1. Number of breakthrough infections in the 24 months period will be used to compare the effectiveness between the vaccines [ Time Frame: The change from first vaccination until 24 month ]
    Number of confirmed positive SARS-CoV-2 tests reported via the national testing system.

  2. Assessment of the safety of the vaccines will be compared between groups [ Time Frame: From first vaccine until Day 90 ]
    Reports of participants with local and systemic reactions to the vaccination will be collected

  3. Assessment of any Adverse Event from the vaccines will be compared between groups [ Time Frame: From first vaccine until Day 90 ]
    Reports of participants with grade 3 and 4 Adverse Events and any Serious Adverse will be collected
