Impact of video-led educational intervention on uptake of influenza vaccine among the elderly in western China: a community-based randomized controlled trial

Abstract

Background Influenza vaccination coverage rate among the elderly is low in China. We aimed to evaluate the impact of video-led educational intervention on influenza vaccine uptake among the Chinese elderly. Methods A randomized controlled trial was conducted in 8 communities of Xi’an, a representative city in western China. Elderly aged over 60 years were randomized to the control group and intervention group (12-minute video education on influenza and its vaccination). Participants’ knowledge, attitudes, and practices (KAP) of influenza was assessed by using a questionnaire survey before and after the intervention. The primary outcomes were participants’ willingness to get influenza vaccinated and their actual uptake rates in the 2020-21 flu season. Secondary outcomes were the variations of pre- and post-intervention KAP scores. Intention-to-treat analysis was performed to analyze the data, and sensitivity analyses were conducted to examine the robustness of the results. Results A total of 350 people were enrolled, with 175 individuals for each group. Participants in the intervention group were more willing to receive influenza vaccination than those in the control group (64.6% vs. 51.4%, p<0.05). The influenza vaccination uptake rate occurred in 10.3% of participants in the intervention group and 3.4% in the control group (odds ratio, 3.23; 95% CI 1.25-8.32, p<0.001). The post-intervention KAP scores in the intervention group were significantly higher compared to those in the control group (p<0.001). Conclusion Video-led education was an effective and feasible approach to improve old people’s willingness and uptake of influenza vaccination in western China.

Education increases COVID-19 vaccine uptake among people in Canadian federal prisons in a prospective randomized controlled trial: The EDUCATE study

“…First, our study was conducted in four of 43 Canadian federal correctional facilities where all incarcerated people were male, thereby decreasing the generalizability of our results to other correctional institutions or to those who house women. That said, gender has not been found to predict vaccine uptake in prior studies utilizing educational interventions [13] , [33] , [34] . Second, we made the assumption that the reasons for vaccine refusal identified during prior qualitative research conducted among this population [9] , [12] were generalizable to the entire federal incarcerated population.…”

The epidemiological trends of 45 national notifiable infectious diseases in China: An analysis of national surveillance data from 2013 to 2022

“…Most of the epidemic outbreaks are dominated by norovirus since 2013, and the key to blocking them is to reduce environmental pollution and focus on dietary safety [48]. It also shows that the incidence and case-fatality rates of in uenza have increased rapidly during the last decade, with low in uenza vaccine coverage being an important reason for its high prevalence [49][50][51]. High incidence of the disease also increases the risk of death in speci c populations, especially in people older than 60 years [52].…”
