NCT00168558

Brief Summary

The specific aims are to examine in Guinea-Bissau:

  • whether the standard titre Schwarz (SW) or standard-titre Edmonston-Zagreb (EZ) measles vaccine will be the best vaccine strain for use in a routine one-dose measles vaccination schedule and a two-dose measles vaccination schedule in terms of antibody response, protection against measles and child survival, and
  • whether the standard-titre Edmonston-Zagreb (EZ) vaccine will be suitable for use in a very early two-dose schedule vaccinating at 4½ and 9 months of age

Study Arms (3)

1

ACTIVE COMPARATOR

Standard titre Edmonston-Zagreb measles vaccine at 4½ and 9 months of age

Biological: Measles vaccine

2

ACTIVE COMPARATOR

Standard titre Schwarz measles vaccine at 9 months of age

Biological: Measles vaccine

3

Interventions

Measles vaccineBIOLOGICAL

The children will be randomised to the following three arms: Arm 1 - Very early two-dose: V (EZ) 4½ mo of age + V (EZ) 9 mo of age. Arm 2 - 9 months one- or two-dose: V (SW) 9 mo of age + V (SW)/or nothing 18 mo of age. Arm 3 - 9 months one- or two-dose: V (EZ) 9 mo of age + V (EZ)/or nothing 18 mo of age. V = measles vaccination, EZ = standard titre Edmonston-Zagreb measles vaccine, SW = standard titre Schwarz measles vaccine
