Clinical Trial Summary

The purpose of this trial is to assess if the rate of febrile reactions following the co-administration of a booster dose of pneumococcal conjugate vaccines with standard infant vaccines is lowered when paracetamol is given prophylactically and to assess the impact of pneumococcal conjugate vaccine on pneumococcal and H. influenzae nasopharyngeal carriage compared to control group receiving meningococcal conjugate vaccine (GSK134612).
