NCT04644159

Brief Summary

An initial retrospective epidemiological investigation was conducted in a city north of France after the diagnosis of the first case of COVID-19 on February 2020. Sero-epidemiological studies were conducted in this town by the Institut Pasteur in early 2020 among families, teachers and non-teaching staff of the high and elementary schools. The goal of this new project is to better characterize the specific immunity generated by the infection within this community. The specific immune response to the SARS-CoV-2 virus will be followed for a period of 2 years from the initial circulation of the virus, within a large cohort of participants covering all age groups from 5 years-old onwards. The study will focus on systemic humoral and cell responses, immunity of the nasopharyngeal mucosa and the humoral response present in saliva. Follow-up of participants in this cohort and monitoring of the virus circulation within this community would help to determine the protective character against re-infection of the natural immunity generated by SARS-CoV-2.
