The COMMUNITY (COVID-19 Immunity) Study

The COMMUNITY (COVID-19 Immunity) Study was initiated in April 2020 and comprises a large longitudinal cohort including 2149 healthcare workers and 118 hospitalized COVID-19 patients. The overall aim is to obtain deep understanding of the generation and dynamics of SARS-CoV-2 immunity (humoral and cellular) following infection and/or vaccination.


Blood and airway samples are obtained every four months, and relevant clinical data are mapped by continuous data collection through a smart-phone app system. Data on vaccination and SARS-CoV-2 infections are obtained from national registers. Substudies, such as regular qPCR screening studies are conducted in subgroups.

The majority of study participants are now vaccinated with either Pfizer's mRNA vaccine BNT162b2, Astra Zeneca's adenovirus vector vaccine ChAdOx1 nCoV-19, and/or Moderna’s mRNA vaccine mRNA-1273.

Key results

The COMMUNITY project is financed by Jonas and Christina af Jochnick Foundation, Region Stockholm, Folkhälsomyndigheten, Lundblad Family Foundation, Hjärtlung fonden, and Knut and Alice Wallenberg Foundation.
