Summary:

      The purpose of the study is to evaluate the immunogenicity and safety of Kinrix when
      co-administered with varicella (Varivax® [varicella virus vaccine live], Merck and Company)
      and (measles mumps rubella) MMR vaccines, compared to Kinrix co-administered with MMR vaccine
      alone. Both Kinrix and the second dose of Varivax are indicated in children 4-6 years of age,
      and there is great potential for the vaccines to be given concurrently. The aim of this trial
      is to demonstrate that co-administered Varivax does not negatively affect the immunogenicity
      or reactogenicity of Kinrix.
