Dataset from A Phase I/II, Randomized, Observer Blinded Study to Evaluate and Compare the Safety, Reactogenicity and Immunogenicity of GlaxoSmithKline Biologicals' Investigational Pneumococcal Vaccine Formulations Versus a Licensed Non-GlaxoSmithKline Biologicals' Vaccine and GlaxoSmithKline Biologicals' Aluminum-based 10-valent Pneumococcal Conjugate Vaccine, in Healthy Elderly Subjects

As the licensed pneumococcal vaccine is not always satisfactory in elderly, new investigational pneumococcal vaccines are evaluated in the healthy elderly population. Note: The study consists of the primary phase (106068): vaccination and follow-up and the extension (106072) of the primary phase: 1 year follow-up. This protocol posting details the procedures of both the primary & extension phase.
