Immunogenicity and reactogenicity of a combined fully liquid DTPw–HepB–Hib pentavalent vaccine in healthy infants: no clinically relevant impact of a birth dose of hepatitis B vaccine

The present study demonstrated that the fully liquid DTPw-HepB-Hib vaccine was safe and immunogenic when administered using a 2-4-6 months immunization schedule, regardless of whether or not infants had received a dose of HepB vaccine at birth.
