Title: Tolerability and Measurability of the Efficacy of Non Pharmaceutical Measures to Prevent Seasonal Influenza
Brief Summary: With this study the investigators will try to assess the tolerability and measurability of the efficacy of non pharmaceutical measures to prevent seasonal influenza in individual households. Households with an identified index case of influenza will be randomised into one of three intervention arms: 1. group, where the household will receive general information about transmission of influenza virus and means to prevent it (Controls); 2. group, which will receive surgical masks and be asked to wear them whenever they are in close contact with the index case or other persons of the household that became ill during the observation period; 3. group, which will be given and asked to wear surgical masks as well as to execute intensified hand hygiene.

In addition to assessing the secondary attack rate as our primary outcome measure, the investigators will also try to evaluate compliance to those interventions by questionnaires.

B: Secondary infection with influenza of the household members who are healthy at the start of the study
C: Immunoglobulin A (IgA) Seroconversion: 6 & 10 Week vs. 6, 10, & 14 Week Vaccination Schedules (4-weeks post-vaccination (All Groups) and 8 weeks post-vaccination (6 & 10 week Group))
D: Frequency of vaccine-related solicited adverse events (AEs) that occur during the acute monitoring phase of the study, the first 28 days after inoculation (Measured through Day 28); Severity of vaccine-related solicited AEs that occur during the acute monitoring phase of the study, the first 28 days after inoculation (Measured through Day 28); Frequency of vaccine-related lower respiratory illness (Measured through Day 56); Proportion of participants that develop 4-fold or greater rises in RSV-neutralizing antibody titer following vaccination (Measured through Day 56)
