Details and patient eligibility

About

This study is to evaluate the safety, tolerability and immune response when 13-valent pneumococcal conjugate vaccine (13vPnC) and the trivalent inactivated flu vaccine (TIV) are given together to healthy adults aged 50-59 years who are naive to 23-valent pneumococcal polysaccharide vaccine (23vPS), or when the vaccines are given 1 month apart. It will also evaluate the immune response to 13vPnC once per year for 4 years and then to a second dose of 13vPnC given 5 years after the first dose.
