Summary

The purpose of this study is to determine if revaccination with pneumococcal vaccine (PNEUMOVAX™ 23, V110) is well tolerated and produces an immune response in older Japanese adults. The primary hypothesis being tested is that the geometric mean concentration of antibodies to pneumococcal polysaccharide serotypes 3, 6B, and 23F at 4 weeks after revaccination will be superior to that before revaccination in Japanese adults who received a primary vaccination at least 5 years before revaccination.
