[Analysis of the refusal of the flu vaccination (REGRIVI study)]

Abstract

Introduction: The objective of this study is to determine the reasons for refusing the flu vaccination in the Primary Care Health Centre of Vilanova de Arousa, Spain, as well as to evaluate the flu vaccination coverage after an educational intervention.

Material and methods: A quasi-experimental before and after study was conducted after an educational intervention on a total of 73 people that included those Primary Care Health Centre patients from Vilanova de Arousa who had refused the flu vaccination in 2014, and who did not meet the exclusion criteria (death during 2014 and 2015 campaigns, non-acceptance of participation, vaccine registration mistakes, contraindication or no indication for the vaccine, inability to contact). After a brief educational intervention, vaccination data from those patients in the 2015 and 2016 campaigns were checked. A descriptive analysis of the variables under study was then carried out. Of the 73 patients initially included, 72 completed the study.

Results: The main reasons for refusing a vaccination were the concerns about the adverse effects and patient perception of good health. Vaccination coverage was 50.7% in 2015, and 48.6% in 2016.

Conclusions: The reasons for refusing vaccination are approachable with a brief intervention since the refusal decreases by half in the long-term.
