The Influence of the COVID-19 Pandemic on Seasonal Influenza Vaccine Uptake Among Patients Visiting a University Hospital in Saudi Arabia.

introductionInfluenza vaccination is a subject of importance in Saudi Arabia. The study measured the uptake of annual influenza vaccination from 2019 to 2021 among patients attending outpatient clinic of a University Hospital.  Materials and methods: A cross-sectional study design was used, and the questionnaire was administered by trained interviewers. Descriptive and inferential statistics were done using the Statistical Package for the Social Sciences (SPSS) version 21 (IBM, Armonk, New York).  Results: The three-year annual influenza vaccine uptake for 2019-2021 was 19.7%, 11.4%, and 14.2%, respectively. In the year 2022, only 28.2% of the patients were offered influenza vaccines by their physicians, and among those offered, 49.6% showed vaccine acceptance. Higher vaccine acceptance was significantly associated with past episodes of influenza infection (p<0.001) and vaccination history before the COVID-19 pandemic (p<0.001). Lower acceptance of the influenza vaccine was observed during the pandemic (p<0.001) and lower uptake among those who were not offered influenza vaccines (p=0.02). No association was found between influenza vaccine acceptance and smoking status, chronic illness, history of COVID-19 infection, or living with those susceptible to influenza. Reasons for vaccine denial include an assumption of not being at risk, a lack of information about the vaccine, and a fear of side effects.

conclusionThe COVID-19 pandemic has had a detrimental effect on annual influenza vaccination. Efforts must be taken to increase influenza vaccination among vulnerable groups.
