Training needs assessment of European frontline health care workers on vaccinology and vaccine acceptance: a systematic review

Abstract

Abstract Background The issue of reluctance towards vaccination is becoming more worrisome. Health care workers (HCWs) are the primary point of contact with individuals who make decisions about vaccination. Therefore, it is crucial that HCWs receive sufficient training and periodic updates. The main objective of this systematic review is to evaluate the HCWs’ training needs in vaccination and vaccine uptake. Methods In February 2022, a search was conducted on MEDLINE, Scopus and Google Scholar databases. The search included papers written in English, Italian, Portuguese, Spanish, French and Romanian, with a publication date ranging from 1 January 2011 to 24 February 2022 and conducted in Europe. To assess the methodological quality of the papers, the Appraisal tool for Cross-Sectional Studies was utilized. Results The search of scientific literature yielded 640 outcomes on PubMed, 556 on Scopus and 15 on Google Scholar, for a total of 1211 records. After eliminating duplicates, screening titles and abstracts and evaluating the full text of the articles, only 25 of them were found suitable for inclusion. The studies’ overall quality ranged from moderate to good. The majority of the research emphasized the need for improved knowledge of vaccine-preventable diseases, vaccine efficacy, immunization schedules and vaccine adverse effects. Conclusions It is vital to prioritize educational programmes on vaccinology and vaccine hesitancy for HCWs, with the objective of improving their knowledge, awareness and attitudes. Addressing the diversity of educational backgrounds, roles and training requirements of HCWs involved in vaccination across Europe is a critical issue that must be tackled for future initiatives.
