The Role of Pharmacists in Counteracting Vaccine Hesitancy: Effectiveness of the 2019 Carnia Project in Improving Adherence to Influenza Vaccination among Target Population

Abstract

Vaccine hesitancy has been included among the top ten threats to global health by the World Health Organization. Pharmacists can play a pivotal role in removing the individual barrier to vaccination, because of the relationship of trust they have with citizens and their ease of access. The aim of this study was to examine the impact of a pharmacy-based intervention to support the 2019 influenza vaccination campaign conducted in the Carnia district through one-to-one counseling. We analyzed data collected by pharmacists between 22 October 2019 and 20 January 2020, and trends in vaccination adherence in the context of the Local Health Authority and the entire province of Udine since 2016. The results showed that 77.2% of people who had not received an influenza vaccination in the previous year changed their minds about vaccination after receiving counseling. The pharmacy-based intervention improved influenza vaccination adherence in the target district (+13.4%), even when compared to the neighboring district of Gemona or considering the data in the broader local and provincial context, and this effect was particularly pronounced among those aged 65 to 74 years (p < 0.01). Considering these findings, pharmacies should be more effectively involved in the provision of public health services aimed at improving accessibility, timeliness, and equity.
