- Children should not have:
- received more than 4 doses of Hib or meningococcal serogroup C and Y vaccine
- Written informed consent obtained from the parent or guardian of the subject.
- Healthy subjects as established by medical history and clinical examination before entering into the study
- Having completed the fourth dose vaccination of study Hib-MenCY-TT-005/006
