To Determine the Safety and Efficacy of Liquid ROTAVAC 5C Vaccine Against Childhood Diarrhea Caused by Rotavirus

Study Rationale A single Rotavirus vaccine container with the vaccine virus and antacid buffer would be ideal for logistical, administrative and distribution ease, especially in routine immunization program. * The advantages of the liquid vaccines are: Liquid vaccines take lesser time to administer compared to the current practice of giving antacid buffer prior to vaccine which takes 40% more time to administer. * Easier to transport as it is stable at 2-80C compared to the frozen formulation that needs to be stored at -200C and transported in dry ice. * Chances of human error during administration are lesser than the sequential administration of antacid and vaccine.
