BACKGROUND: A busy pharmacy workload may limit a pharmacist's ability to meet the needs of vaccine-willing patients and also contribute to missed opportunities to engage with vaccine hesitant individuals. Opportunities for pharmacy technicians to support vaccination services may play a role in addressing increasing patient vaccination needs. PURPOSE: This research aims to review the role of pharmacy technicians in vaccination services that is supported by pharmacy practice research to date. METHODS: In compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocols, systematic searches were performed in PubMed, Embase, International Pharmaceutical Abstracts, Scopus, and CINAHL. Articles published through June 2020, in French, English, and Spanish, were screened for eligibility. Two independent reviewers screened titles and abstracts for inclusion. Data extraction of included study methodologies and results was performed by one reviewer and verified by a second reviewer. RESULTS: A total of 656 records were identified through the search of published literature. Full-text screening of 145 records identified 14 articles for inclusion. Most articles evaluated emerging pharmacy technician roles in patient screening (n = 8, 53%) and vaccine administration (n = 5, 36%). Implementation of both emerging roles demonstrated positive patient outcomes (n = 10, 72%). Screening activities were complicated by the complexity of the role, as well as its potential to increase overall time spent on vaccination services. Pharmacists and technicians advocated for accredited vaccine administration training owing to consistent benefits in pharmacy workflow efficiency, pharmacist clinical time, and pharmacy technician job satisfaction. CONCLUSION: This review supports the effective deployment of pharmacy technicians in delivering vaccination services. Despite pharmacy technician vaccine administration roles being highly regulated, professional advocacy by pharmacists and technicians can use the advantageous training, workflow, and patient outcomes benefits presented in this review. Early adopters of professional practice advancements for pharmacy technician vaccine administration may expand vaccination service capacity efficiently and safely, thereby reaching more patients.
