Cómo lo describe el promotor
En el documentoEn inglés, del registroThe aim of this study is to determine the efficacy of Fluzone High-Dose compared to standard dose Fluzone for laboratory-confirmed or culture-confirmed influenza caused by influenza types/subtypes that are similar (for laboratory-confirmed) or antigenically similar (for culture-confirmed) to those contained in the respective annual vaccine formulations. Primary Objective: * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to laboratory-confirmed influenza caused by any influenza viral types/subtypes, associated with the occurrence of a protocol-defined influenza-like-illnesses (ILI). Secondary Objectives: * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to laboratory-confirmed influenza, caused by any influenza viral types/subtypes, associated with the occurrence of a protocol-defined ILI. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza, caused by any influenza viral types/subtypes, associated with the occurrence of a protocol-defined ILI. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza caused by viral types/subtypes antigenically similar to those contained in the respective annual vaccine formulations, associated with the occurrence of a modified Centers for Disease Control and Prevention (CDC)-defined ILI. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza caused by any influenza viral types/subtypes, associated with the occurrence of a modified CDC-defined ILI. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza caused by viral types/subtypes antigenically similar to those contained in the respective annual vaccine formulations, associated with the occurrence of a respiratory illness. * To compare the clinical efficacy of Fluzone High-Dose to that of Fluzone in elderly adults, with respect to culture-confirmed influenza caused by any influenza viral types/subtypes, associated with the occurrence of a respiratory illness.
