Purpose
Streptococcus pneumoniae are bacteria which normally live in the upper respiratory tract of humans. However, these bacteria can also cause severe infectious diseases such as pneumonia, septicemia and meningitis. Elderly subjects are especially vulnerable to these infections, and the diseases can result in death. The currently available licensed Streptococcus pneumoniae vaccine is recommended for prevention of pneumococcal diseases in individuals over the age of 65. However, the antibody level elicited by this vaccine, is not always satisfactory in elderly people. To overcome the problem, GlaxoSmithKline Biologicals is currently developing candidate vaccines that are hoped to work better than the currently available vaccines. As a first step in this development, the present study is being conducted in order to evaluate the immune response to the currently marketed vaccine.

Primary Outcome Measures:
- Response rate to 11 vaccine serotypes [ Time Frame: One month post vaccination ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Anti-polysaccharide total IgG ELISA for 11 vaccine pneumococcal serotypes [ Time Frame: At all time points ] [ Designated as safety issue: No ]
- Opsonophagocytic activity against 11 vaccine pneumococcal serotypes in a subset of subjects [ Time Frame: At Day 0 and Day 30. ] [ Designated as safety issue: No ]
- The rank of subjects from "poorest responder" to "best responder" based on the number of serotypes each subject responds to [ Time Frame: One month post vaccination ] [ Designated as safety issue: No ]
- Persistence of the immune response in a subset of subjects. [ Time Frame: Until Month 36. ] [ Designated as safety issue: No ]
- Opsonophagocytic activity response in a subset of subjects. [ Time Frame: At Day 30 ] [ Designated as safety issue: No ]
- Occurrence of serious adverse events (SAE). [ Time Frame: Up to 1 month after vaccination. ] [ Designated as safety issue: Yes ]
- Occurrence of study related SAEs. [ Time Frame: Throughout the study period. ] [ Designated as safety issue: Yes ]

Detailed Description:
Since influenza vaccination is recommended in the age range of the study population, Fluarix™ (GlaxoSmithKline Biologicals) vaccine will be offered free of charge for the study period (3 consecutive years), to be used by Investigators according to national vaccination schedule/practice.
The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007
Eligibility| Ages Eligible for Study: | 65 Years and older |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | Yes |
Criteria
Inclusion criteria
