Per-protocol analysis on the 902 non-immunized participants who were able to be contacted.

¹Period of stay was longer than 3 mo;

²Couverture médicale universelle, health insurance coverage that is given to persons living in precarious situations (i.e. unemployed, poverty, etc;

³Couverture médicale universelle complémentaire, additional health insurance coverage that is given to stable residents in France living with limited financial resources;

⁴Aide médicale d’état, health insurace generally given to immigrants without proper documentation;

⁵When constructing the multivariable model, gender was not included due to collinearity with men who have sex with men.
