GlaxoSmithKline1,259 enrolled

Overview

The purpose of this study is to compare two measles, mumps and rubella conjugate vaccines (manufactured by GSK and Merck and Company ) in terms of the immune response elicited and safety with a six month follow-up after first vaccination. Additionally, antibody persistence will be assessed one and two years after administration of MMR vaccine. The Protocol Posting has been updated following Protocol amendment 1 and 2, Oct 2009.
