The study will evaluate the safety, immunogenicity,immune persistence and lot-to-lot consistency of Diphtheria,Tetanus and Acellular Pertussis (Three Components) Combined Vaccine, Adsorbed, (DTacP) including 2 parts: PART 1 will evaluate the safety and immunogenicity of DTacP in health infants aged 2 months and 3 months compared with an adsorption Tetanus-diphtheria-acellular Pertussis (DTaP) Vaccine and Diphtheria,tetanus,pertussis(acellular,component),poliomyelitis(inactivated) vaccine(absorbed) and Haemophilus influenzae type b conjugate vaccine (PENTAXIM),compare the safety and immunogenicity of DTacP with different immunization schedules, and observe the immune persistence. PART 2 will evaluate the lot-to-lot consistency of DTacP in health infants aged 3 months with the 3-dose schedule of 3-4-5 month.
