Factors Affecting Influenza Vaccination Uptake and Attitudes among Lebanese University Students: The Impact of Vaccination Promotional Programs and COVID-19 Pandemic

Vaccination is the most effective preventative strategy against influenza, yet university students' influenza vaccination uptake remains low. This study aimed firstly to determine the percentage of university students who were vaccinated for the 2015-2016 influenza season and to identify reasons for non-vaccination, and secondly to examine the impact of external factors (on-campus/online influenza awareness campaigns and COVID-19 pandemic) on their influenza vaccination uptake and attitudes for the 2017-2018 and 2021-2022 influenza seasons. A descriptive study was conducted over three phases for three influenza seasons at a Lebanese university in the Bekaa Region. Based on data collected in 2015-2016, promotional activities were developed and implemented for the other influenza seasons. This study was conducted using an anonymous, self-administered questionnaire by students. The majority of the respondents in the three studies did not receive the influenza vaccine (89.2% in the 2015-2016 study, 87.3% in the 2017-2018 study, and 84.7% in the 2021-2022 study). Among the unvaccinated respondents, the main reason for non-vaccination was that they thought that they did not need it. The primary reason for vaccination among those who were vaccinated was that they believed they were at risk of catching influenza in a 2017-2018 study and due to the COVID-19 pandemic in the 2021-2022 study. As for attitudes towards influenza vaccination post-COVID-19, significant differences were shown among the vaccinated and unvaccinated respondents. The vaccination rates among university students remained low despite of the awareness campaigns and COVID-19 pandemic.
