Willingness of receiving influenza vaccine and its influencing factors among health care workers in Yangtze River Delta region from 2020 to 2021

Abstract

Objective: To analyze the willingness of receiving influenza vaccine and its influencing factors among health care workers (HCWs) in Yangtze River Delta region from 2020 to 2021. Methods: Convenient sampling method was adopted. From July 2020 to March 2021, 76 hospitals in Jiangsu, Zhejiang, Anhui and Shanghai provinces were selected according to the hospital level and job position, and a questionnaire survey was conducted on the willingness of receiving influenza vaccination. Logistic regression model was used to analyze the influencing factors of vaccination intention. Results: A total of 1 332 HCWs were investigated, with a ratio of male to female about 1∶3.2, and the length of working years was (15.07±9.75) years. A total of 614 HCWs had received influenza vaccine in 2019, with a vaccination rate of 46.09%. About 63.21% (842/1 332) of HCWs were willing to be vaccinated with influenza vaccine. The results of binary logistic regression analysis showed that the willingness of receiving influenza vaccine among HCWs in primary hospitals was higher than that in secondary hospitals (OR=0.573) and tertiary hospitals (OR=0.357). The willingness of HCWs who had received influenza vaccine in 2019 was higher than that of HCWs who had not received influenza vaccine (OR=0.226) and had unknown history of influenza vaccination (OR=0.228). The willingness of HCWs in departments of prevention, health care and infection was higher than that in departments of pre-examination, outpatient, emergency, pediatrics and respiratory (OR=1.670). Conclusion: The willingness of receiving influenza vaccination among HCWs in Yangtze River Delta region is high, but it is still lower than that in developed countries. It is necessary to strengthen publicity and education to improve the influenza immunization level of HCWs.
