Title

A randomized controlled trial of two versus three doses of Rotarix™ vaccine for boosting and longevity of vaccine immune responses in Zambia.

Objectives

Objective 1. Assess boosting and longevity of antibody responses between infants receiving two versus three doses of Rotarix™ vaccine and evaluate safety of third dose. Objective 2: Profile innate and adaptive cellular, cytokines and secretory antibodies responses to Rotarix™ vaccination and investigate influence of cytomegalovirus exposure Objective 3: Determine genotypes and phenotypes of HBGA profiles and assess association with Rotarix™ vaccine immunogenicity Objective 4: Profile changes in rotavirus specific antibody titres and non-immunological components in maternal breastmilk over time and determine association with infant vaccine response

Study Design

The proposed clinical trial is a phase IV or post licensure trial. It will have two arms and will be an open-label randomized controlled trial of two versus three doses of live, attenuated, oral Rotarix™ administered at 6 & 10 weeks (the standard of care arm) and at 6 & 10 weeks plus 9 months infants age (the experimental arm). The intervention in the experimental arm is an added third dose of Rotarix™ vaccine given at 9 months infant age
