Protecting adults against pneumococcal disease
Study hypothesis

Condition
Pneumococcal disease
Intervention
Interventions used are the Heptavalent pneumococcal conjugate vaccine (Prevenar ®, Wyeth Vaccines) and 23-valent pneumococcal polysaccharide vaccine (Pneumovax® II, Sanofi Pasteur MSD). Participants will be randomised to receive either:
1. Two doses of the 7-serotype vaccine (Prevenar®) followed by one dose of the 23-serotype vaccine (Pneumovax® II)
2. One dose of the 23-serotype vaccine (Pneumovax® II) followed by two doses of the 7-serotype vaccine (Prevenar®)
3. One dose of the 7-serotype vaccine (Prevenar®) followed by one dose of the 23-serotype vaccine (Pneumovax® II, followed by a further dose of the 7-serotype vaccine (Prevenar®)
All vaccines will be administered at 0, 6 and 12 months.

Primary outcome measures
Absolute antibody concentration to Pn23 after a one or 2 dose priming immunisation with Pnc7.
Secondary outcome measures
1. Characterisation and measurement of the B cell responses and assessment of memory induction following the three different immunisation regimes
2. Number and nature of any adverse events occurring during the study

9. Have any condition which, in the opinion of the investigator, might interfere with the evaluation of the study objectives
10. Participation in another clinical trial investigating a vaccine, a drug, a medical device, or a medical procedure
