Title: The Immunogenicity of Rotavirus Vaccine Under Different Age Schedules and the Impact of Withholding Breast Feeding Around the Time of Vaccination on the Immunogenicity of Rotarix Vaccine
Brief Summary: Rotavirus is one of the most common causes of severe diarrhea, responsible for 40% of all diarrhea related deaths in children worldwide. Two vaccines against Rotavirus, Rotarix® and Rotateq® were licensed in many high and middle income countries in 2006, but lack of efficacy data in low income countries had prevented WHO from making a universal recommendation of their use until recently. This study will be conducted in Pakistan and will look at two objectives:

1. To compare the immunogenicity of Rotarix® vaccine when administered at 6 and 10 weeks of life and at 6, 10 and 14 weeks of life.
2. To compare the immunogenicity of Rotarix® vaccine in infants breast fed at the time of vaccine administration with infants whose breast feeding is withheld for one hour before and after vaccine administration.
