Inclusion criteria
Inclusion criteria: 1. Participants recruited from General Practices in the northern England, Leeds, UK area who were not taking part in a centralized influenza vaccination invitation scheme in Autumn 2012 2. The study population consisted of all patients in each practice eligible for an influenza vaccination that year by being age 65 years or over at their next birthday 3. A total of 13,806 patients were individually randomly assigned to one of eight conditions using a random number generator. Subsequently, 354 patients were deemed ineligible for vaccination (i.e., due to having left the General Practice, being deceased, unable to have a vaccination due to a medical condition, or having already received a vaccination) and excluded from the study, leaving 13,452 patients who were included in intention-to-treat analyses 4. A total of 4934 completed questionnaires (43.1%) were returned from 11752 sent out. The sample was 56.2% female with a mean age of 75.5 years (SD = 7.88) and mainly lived in areas of low deprivation (Townsend score M = -1.49, SD = 2.93). The eight different conditions were equivalent on gender and age but significantly different on deprivation
