Brief Summary:
The trial will investigate to what extent SMS reminders for influenza vaccination increases coverage of influenza vaccination among elderly from the majority population and among elderly from immigrant groups with low vaccination coverage
Detailed Description:
Background The coverage of influenza vaccination among elderly in Norway is insufficient especially in some immigrant groups To improve public health there is a need for an intervention that can increase influenza vaccination coverage Further interventions tailored to reduce potential barriers among immigrants can reduce health inequities
Objective InfluSMS aims to determine if SMS nudging increases vaccination coverage among those aged 65 or older i in Norways general population ii among immigrants born in Poland iii among immigrants born in Ukraine and to evaluate the impact of SMS nudging in Norwegian versus in the official language of the native country of immigrants born in Poland or Ukraine
Methods InfluSMS is a pragmatic randomized controlled trial conducted among people aged 65 or older residing in Norway Influenza vaccination coverage is the main outcome measured in control and intervention arms for each of the three populations listed above In all three populations the control arm is standard care ie no individual reminder for influenza vaccination All populations have an intervention arm that will receive an SMS nudge in the Norwegian language In addition the Polish and Ukrainian immigrant populations include a second intervention arm that will receive an SMS nudge in Polish or Ukrainian respectively Allocation to study arm is randomized and the intervention will take place at the start of the 20252026 influenza season All eligible individuals will be passively followed up through the National Immunisation Registry SYSVAK from which individual influenza vaccination status three months after the SMS nudge will be extracted
Results Inclusion of participants will start in the third quarter of 2025 and the registry data will be available in the first quarter of 2026 Coverage rates of each strategy and coverage differences between strategies will be presented
Implications SMS nudging could be integrated into the national influenza vaccination program if the trial shows it effectively increases influenza vaccination coverage among the elderly Further the trial will establish whether language is a barrier for influenza vaccination uptake among recent immigrant groups that have low influenza vaccination coverage and to what extent this potential barrier can be diminished by SMS nudging in the official language of their native country
