Second Extension Study to Evaluate Safety and Tolerability of Influenza Vaccines in Adults and Elderly, and to Evaluate Immunogenicity and Concomitant Vaccination With Pneumococcal Vaccine in a Subgroup
Summary
The study primarily aims to evaluate immunogenicity and safety of influenza vaccines (cell culture derived seasonal trivalent influenza vaccine (cTIV) or influenza virus vaccine (egg-derived seasonal trivalent, thiomersal free; eTIV\_a)) when administered alone and when administered concomitantly with pneumococcal polysaccharide vaccine (PV) in elderly subjects. The study also aimed to evaluate safety and immunogenicity (subset) of annual vaccination with either cTIV or eTIV\_a in adults and elderly subjects.
