Phase IV Interchangeability Study of a Liquid Pentavalent Combination Vaccine

Study Overview
=================
Brief Summary
-----------------
The objective of this study is to compare the Safety and Immunogenicity of a mixed sequence of 2 different pentavalent vaccines (Diphtheria-Tetanus- Pertussis, Hepatitis B and Hib combination Vaccines) with single sequence of Shan 5 in infants.

Official Title
-----------------
A Single Blind, Multicentric, Comparative, Vaccine Interchangeability Trial of Shan 5 (Liquid) and Easy Five (Liquid) [Diphtheria-Tetanus- Pertussis, Hepatitis B and Hib Pentavalent Combination Vaccines] in Indian Infants.

Conditions
-----------------
Diphtheria, Tetanus, Pertussis, Hepatitis B, Haemophilus Influenzae Type B

Intervention / Treatment
-----------------
* Biological: Shan 5
* Biological: Easy Five

Inclusion Criteria: Healthy children in the age group six to eight weeks Born after a normal gestational period (36 - 42 weeks) Mother's HBsAg assured negative. Father, mother or legally acceptable representative properly informed about the study and having signed the informed consent form. Parents willing to fill the Diary Card Exclusion Criteria: Administration of immunoglobulin or any blood products since birth. Use of any investigational, on-registered drug, or vaccine other than the study vaccine (with the exception of OPV & BCG vaccine) during the study period or within 30 days preceding the first dose of the study vaccine.

Major congenital or hereditary immunodeficiency. Infants having evidence of disease or fever, history of allergic disease or persistent hematological, hepatic, renal, cardiac or respiratory disease and signs of a CNS disorder at the time of vaccination. Infants showing any of the following reactions after any dose of study vaccine will be withdrawn for subsequent doses: body temperature more than 40.4 degree Celsius, persistent screaming or crying for 3 hours within 48 hours of vaccination, seizures, encephalopathy and hypersensitivity reaction. Parent/s or guardian of subject unable to maintain diary card Simultaneous participation in any other clinical study
