Hepatitis B (HepB) vaccination for all newborns is the safety net to prevent hepatitis B virus (HBV) infection and its consequences. This study identified socio-demographic factors associated with non-receipt of the HepB birth dose among infants in the United States. National Immunization Survey 2009 data were analyzed. Multivariable logistic models for complex survey data were applied to estimate adjusted risk ratios. The birth dose was defined as receipt of HepB vaccine by day 3 of life. Infants whose parents delayed or refused vaccines, who had one vaccination provider, or were uninsured exhibited higher risks of non-receipt of HepB birth dose (adjusted risk ratio [RR] 1.11 [1.04-1.19], 1.20 [1.11-1.31], and 1.18 [1.08-1.28]). Lack of a state universal policy that supplies HepB vaccine free displayed higher risk of not receiving HepB birth dose (adjusted [RR] 1.19 [1.11-1.29]).
