ABSTRACT
Introduction: In Spain, influenza vaccination is available in companies free of charge for their workers. Despite this, vaccination coverage against influenza is very low in these groups. Objective(s): The aim of this work is to know the reasons for acceptance of influenza vaccination in a working population. Method(s): During the 2021-2022 influenza vaccination campaign, we conducted a survey of two groups of workers at the automobile factories of RENAULT ESPANA S.A. in the cities of Valladolid and Palencia (Spain). The first group (NV) was formed by 304 (33.5%) workers who did not receive the influenza vaccine in the previous season. The second (V) was formed by 604 workers (66.5%) who had been vaccinated against influenza at least the previous season. In the NV group, they were asked the reasons why they did not get vaccinated the previous season and if they did so in 2021-2022. In group V, only the reasons for continuing to be vaccinated were asked. Result(s): In NV, the main reason for avoiding vaccination in the previous season was the lack of perception of the severity of the influenza infection (74.7%), and 31.6% and 29.0% of them decided to get vaccinated during the 2021-2022 season due to the fear of co-infection of SARS-CoV-2 and influenza and medical recommendations respectively. The 83.5% of group V responded that the reason for getting vaccinated in 2021-2022 was their adherence to vaccination. Conclusion(s): The results show that medical recommendation is the best tool to vaccinate workers against influenza and make them adhere to it. Also, the fear to co-infection of COVID-19 and flu was a frequent reason for getting vaccinated, above all in NV.Copyright © 2023
