Influenza Vaccination in Coronavirus Times: Intention to Be Vaccinated by Primary Care Professionals in Central Catalonia (VAGCOVID) (preprint)

BackgroundInfluenza vaccination is the main measure of prevention against the epidemic flu, which annually produces a significant increase in the pressure on healthcare systems, in addition to influencing the absenteeism of health workers. Although it is recommended that health professionals be vaccinated, their vaccination coverage is low. The lack of knowledge about the evolution of influenza in the context of the SARS-CoV-2 coronavirus pandemic led to the continued recommendation of influenza vaccination to people at risk and to professionals. The aim of the study is to determine the intention to vaccinate against seasonal flu of health professionals in the 2020-21 campaign in the context of the SARS-CoV-2 pandemic, and to analyse the factors that influence it.MethodsCross-sectional study through a structured online survey aimed at Primary Care professionals in the region of central Catalonia.ResultsA total of 610 participants responded to the survey, 65.7% of whom intended to be vaccinated against the flu in this campaign and 11.1% did not yet know or did not answer. The intention to be vaccinated against flu is associated with the professional category, the years of professional practice, the fact of making face-to-face guards, and the perception of the risk of suffering from flu. It is also related to a history of influenza vaccination in the previous year and to having been vaccinated on another occasion. The profile of professionals who intend to be vaccinated against flu includes professionals with a history of vaccination, who were on duty and perceived that their staff were at risk of becoming ill with flu.ConclusionsDuring the SARS-CoV-2 pandemic, many professionals show a clear intention to get vaccinated against the flu, but there are still some who doubt it. In order to improve influenza vaccination coverage among health professionals, it is necessary to design strategies aimed at professionals who are hesitant or reluctant to vaccination.

Influenza Vaccination During the Coronavirus Epidemic: Intention to Vaccinate among the at-risk Population in the Central Catalonia Health Region (VAGCOVID). (preprint)

BackgroundInfluenza is a major public health issue, with the primary preventive measure being an annual influenza vaccination. Nevertheless, vaccination coverage among the at-risk population is low. Our understanding of the behaviour of the influenza virus during the SARS-CoV-2 coronavirus pandemic is limited, meaning the influenza vaccination is still recommended for individuals in high-risk groups. The aim of the study is to determine the intention to vaccinate against seasonal influenza among the at-risk population in the 2020-21 campaign during the SARS-CoV-2 pandemic and to analyse the factors which influence said intention.MethodsCross-sectional telephone survey of adults (aged over 18) with risk factors in central Catalonia where the need for the Seasonal Influenza Vaccine (SIV) was recommended.ResultsA total of 434 participants responded to the survey, 43.3% of whom intended to have the vaccination against influenza this year and 15.9% did not know or did not express an opinion. The intention to get vaccinated against influenza is associated with having dependents, the individual’s perception of the risk of them catching influenza and the perceived risk for dependents. It is also associated with age, whether the individual had received an influenza vaccination the year before and whether they had been vaccinated on another occasion. The best predictors of the intention to vaccinate are the individual’s perception of the risk of catching influenza and whether the individual had been vaccinated in the previous year.ConclusionsVaccination intention can be a good predictor of behaviour in relation to vaccination. During the current SARS-CoV-2 pandemic many individuals are undecided. In order to improve vaccination coverage in people at risk, it is necessary to promote educational actions, especially in those people who express doubts.
