ComCor study: new results on places of infection with SARS-CoV-2 and analysis of the efficacy of messenger RNA vaccines against the Delta variant
From May 23 to August 13, 2021, the Institut Pasteur, in partnership with the French National Health Insurance Fund (CNAM), Santé publique France and the Ipsos institute, conducted the fourth part of the ComCor epidemiological study on circumstances and places of infection with the SARS-CoV-2 virus in France. The aim of the study was to identify the socio-demographic factors, places visited and behaviors associated with a higher risk of infection with SARS-CoV-2. The study was also used to carry out a real-world analysis of the effect of previous infection with COVID-19 and the efficacy of messenger RNA vaccines against symptomatic infection with the Delta variant.
