Study information

Scientific title

A phase III randomised, open label clinical trial evaluating the immunogenicity of a 10-valent pneumococcal conjugate vaccine booster compared to the standard 13-valent pneumococcal conjugate vaccine booster given at 12 months of age to healthy children who have received the 13-valent pneumococcal conjugate vaccine at 2 and 4 months of age


Study hypothesis

This is a study to evaluate an alternative booster for pneumococcal conjugate vaccination (PCV) for children at 12 months of age. Currently in the UK, a vaccine called Prevenar 13 (PCV-13), which contains 13 pneumococcal types attached to a molecule (carrier protein) called CRM197, is given to children at 2, 4 and 12 months of age. There is some evidence that a vaccine called Synflorix (PHiD-CV) may be at least as good as the currently used vaccine when given at 12 months of age. Although PHiDCV contains only 10 pneumococcal types, there is evidence that it generates crossreactive antibodies against two of the three additional types included in PCV-13 which might be enough to protect children against these disease types. Furthermore, previous studies have shown that PHiD-CV confers protection against a common otitis media pathogen in children called nontypeable H. influenzae (NTHi) by attachment to a carrier protein called Protein D, which is derived from NTHi. In addition, the use of a carrier protein, which is not closely related to an antigen included in any coadministered or previously administered routine vaccine minimises the risk of interference related to it.

Blood sampling: Study nurse/doctor at the participants' home.

Diary cards: Participants will be asked to record any local/general reactions to vaccine for 4 days after vaccination. In addition any medically significant adverse events occuring between the study visits are to be recorded. All concomitant medication used during this period will also be recorded.

Health assessment: Study nurse/doctor at the participants' home.

Routine vaccines: MMR-Hib-MenC
