Assess Feasibility of an Acellular Pertussis Vaccine (Pa) Given Soon After Birth, Followed by 3-dose Primary Vaccination With the DTPa-HBV-IPV/Hib Vaccine

This study will assess immunogenicity, safety and reactogenicity of primary and booster vaccination.

"There will be two groups in this study:

* one group will receive a birth dose of Pa vaccine and 3 doses of DTPa-HBV-IPV/Hib vaccine as primary vaccination and a dose of DTPa-HBV-IPV/Hib vaccine as booster vaccination
* the control group will receive a birth dose of hepatitis B vaccine and 3 doses of DTPa-HBV-IPV/Hib vaccine as primary vaccination and a dose of DTPa-HBV-IPV/Hib vaccine as booster vaccination".
