The main aim of this study was to find information to encourage healthcare workers globally to get vaccinated against influenza. The objective of this study was to explore the adherence of healthcare workers to immunization measures and to seek the motivating factors to promote the influenza vaccination among healthcare workers. Although the vaccination against influenza is the best precaution to prevent the spread of influenza infection, statistics show that the number of vaccinated healthcare workers is still low. Infectious diseases like influenza, can be easily transmitted and spread over through droplets from one person to another. To reduce the risk of infection, vaccination against influenza is necessary.

Integrative literature review was chosen as the method to complete the study. The data were collected from four different databases in April 2021: CINAL with full text (EBSCO), ProQuest Central, Science Direct (Elsevier) and PubMed. Sixteen studies were included after the inclusion and exclusion process where ten studies were observational studies, four were systematic literature reviews and two studies were qualitative studies. Quality assessment for the observational studies was done by using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE), Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was used to assess the quality of the systematic literature reviews and Critical appraisal skills programme CASP (B) was used for assessing the quality of the qualitative studies.

The factors influencing vaccination acceptance among healthcare workers were demographic factors such as age, gender, chronic illness, knowledge of influenza and vaccination and confidence to vaccination while factors affecting vaccination acceptance were lack of knowledge, fear and doubt, and false beliefs. Educational programmes, communication, encouragement, and access to vaccination were found to be the intervention to promote the vaccination acceptance among healthcare workers.

Therefore, to increase the rate of vaccination among healthcare workers globally, these findings can support healthcare institutions in motivating their employees to get vaccinated against influenza.
