Evaluation of Vaccination Coverage and Determinants of Success of the COVID-19 Vaccination Program Among Populations in Very Precarious Situations

The main objective of the study is to assess the level of vaccination coverage (VC) against COVID-19 among migrants, homeless and travelling community, according to their living conditions and housing.

The secondary objectives are :

* to compare the estimated level of vaccination coverage in the different sites and strata (emergency shelters/hotels, camps, workers' hostels, on the street) with the estimated level in the general population of the same territory obtained from the French Health Insurance data (SIVAC). * identify the obstacles and leverage of vaccination (i.e. mobile team) according to living conditions and habitat (socio-demographic factors, personal health history, vaccine adherence, local health policies, etc.).
