Objectives: To investigate the short-term and long-term effectiveness of different level of financial incentives on increasing the willingness to vaccinate and vaccine uptake.
Methods: A randomized controlled trial was conducted to investigate the effectiveness of financial incentives of three groups with monetary incentives (CNY20, CNY40, and CNY60; 1 CNY=0.13EUR) vs a control group - CNY0- on influenza vaccine uptake among 720 older adults (≥60 years) in Beijing, China. The primary outcome was vaccine uptake, and the secondary outcomes were intention to vaccinate and length of time to immunization.
Results: Financial incentive significantly promoted higher intention to influenza vaccinate 120/178, 67.42% vs. 442/542, 81.55%; RR 1.21, 95%CI 1.02-1.42) and higher vaccination participation (74/178, 41.57% vs. 316/542, 58.30%; RR 1.39, 95%CI 1.10-1.75). CNY60 had the largest impact on the intention to vaccinate (15.00% vs. 13.48% and 13.90%) and vaccination uptake (19.42% vs. 14.05% and 16.67%) compared to CNY20 and CNY40. Time to vaccination was significantly lower among participants receiving incentives than those without ([37.21 days, 95%CI 34.33-39.99] vs. [48.27 days, 95%CI 43.47-53.07]; HR1.57, 95%CI 1.22-2.03). We found no long-term influence of financial incentives on vaccination decisions in the following year (217/542, 40.04% vs. 65/178, 36.52%; RR 1.08, 95%CI 0.82-1.42).
Conclusions: Our study suggests modest financial incentives will boost short-term influenza vaccination rates and shorten the length of time to immunization in China. No one single time financial incentive had a long-term effect on future vaccination behaviours or helped establish regular vaccination behaviours.
