**5. Conclusions**

Rogers' 5 Factors from the Di ffusion of Innovation provide insight into ideal characteristics for encouraging adoption of an innovation. Immunizing is a relatively new role for pharmacy technicians, and consideration of factors that can encourage and ease implementation into pharmacy workflow can aid in future application. The findings of this study included themes such as: (1) Pharmacists' perceived improvement in workflow flexibility; (2) The choice of the correct technician to immunize within the pharmacy; (3) Pharmacists' perceived improved workflow time prioritization; (4) Limited available training as a barrier to implementation; and (5) The initial apprehension and later acceptance of pharmacists with respect to the innovation. Pharmacists are able to focus on the task at hand rather than facing interruptions and delays in checking prescriptions caused by providing walk-in immunizations. The biggest barrier identified by the participant pharmacists was the challenge of getting more technicians trained. Technicians were interested in immunizing and pharmacists supported them in becoming immunizers, but the training was not being o ffered in their area as frequently as they would prefer. As technician immunization administration spreads beyond early adopter states, further research into the impact on pharmacy workflow is needed.
