Descriptive Information
Brief Title  ICMJE Study Evaluating Persistence Of Antibody Response Elicited By 13vPnC In Healthy Adults Previously Vaccinated
Official Title  ICMJE A Study To Evaluate The Persistence Of The Antibody Response Elicited By 13-Valent Pneumococcal Conjugate Vaccine (13vPnC) In Healthy Adults Who Have Previously Been Vaccinated With Either 2 Doses Of 13vPnC Or 13vPnC And 23-Valent Pneumococcal Polysaccharide Vaccine In Different Sequential Order In Study 6115A1-3010 Or 6115A1 3005
Brief SummaryThe purpose of this study is to evaluate the levels of antibodies 1 year after receiving the second vaccine dose in two groups of adults over the age of 60: (1) those who have previously received 2 doses of 13-valent pneumococcal conjugate vaccine (13vPnC) and (2) those who have previously received 1 dose of 13vPnc and 1 dose of 23-valent pneumococcal polysaccharide vaccine (23vPS). This study will also assess whether the use of the 2 vaccines, 13vPnC and 23vPS, administered in different sequential order results in different prolonged antibody levels. This study is limited to individuals who participated in either study 6115A1-3010 (NCT00574548) or 6115A1-3005 (NCT00546572).
