OBJECTIVE: Seasonal influenza vaccination is the main method for influenza prevention. The main objective of this study is to estimate the frequency of vaccinations in patients with chronic illnesses presented to a primary health care (PHC) centre. METHODS: This cross-sectional study was performed in patients admitted to the Kapandriti Health Centre. Their vaccination status with an influenza vaccine and their underlying diseases were recorded. RESULTS: 34.8% of the subjects had been vaccinated against seasonal influenza. Vaccination coverage was found to be 53.9% in pulmonary, 55.6% in chronic kidney disease, 43.7% in cardiovascular disorders, 40.6% in diabetes, 40.6% in any kind of malignancy, and finally 33.3% in neurological patients. The most significant predictors for vaccination were the age group of 60 to 79 years (OR = 3.08, 95% CI: 1.79-5.29), age over 80 years (OR = 2.91, 95% CI: 1.58-5.36), respiratory disease (OR = 2.25, 95% CI: 1.33-3.76), cardiovascular disorder (OR = 1.46, 95% CI: 1.02-2.10), and 3 to 5 visits to the unit annually (OR = 1.57, 95% CI: 1.12-2.24). Finally, it was discovered that coexistence of one to three diseases reduced the likelihood ratio for vaccine uptake (OR = 0.15, 95% CI: 0.03-0.79, p < 0.05). CONCLUSIONS: The influenza vaccination rate for the population of the present study has been found higher than that reported previously in literature. We believe that there is a need to implement new and more effective strategies such as educating vulnerable groups on the benefits of vaccination and so reducing the incidence of influenza and its complications especially in vulnerable groups.
