Family history of immigration from a tuberculosis endemic country and low family income are associated with a higher BCG vaccination coverage in Ile-de-France region, France

After withdrawal of multipuncture BCG device from the French market in January 2006, vaccination coverage (VC) with the intradermal device has dropped and since remained sub-optimal in Ile-de-France, the only region of mainland France where BCG is recommended to all children. We conducted a cross-sectional study to identify socio-economic factors associated with BCG VC in children of Paris metropolitan area born after January 2006. Two-stage random sampling was used to include 425 children up to 5 years old from Paris and its suburbs. Information was collected through face-to-face interviews and vaccination status confirmed by a vaccination document. Poisson regression analyzed the association between VC and potential determinants. VC of children from families with the lowest incomes (first quartile of family income/consumption unit (CU) (<883 (sic)) was close to 100% regardless of family origin. In families with higher incomes (>= 883 (sic)/CU), VC was significantly higher among children born to families from a tuberculosis highly endemic country (98.2%) compared with other children (76.2%) (p = 0.004). Children of low socio-economic background as well as those with a family history of immigration, regardless of family income, are correctly identified as being at high risk of tuberculosis and properly vaccinated with BCG in this area.
