The increasing growth of accessible vaccinations has raised the overall expenses of the vaccine program and put pressure on immunization providers. In England, GP practices responsible for vaccinating their local population received £227 million. However, the costs of bringing the program to general practice, as well as the variables driving these costs, remain unclear. As a result, the goal of this study was to assess the costs of implementing the regular immunization program at GP practices in England, identify organizational variables that influence costs, and compare them to the money received. Time Driven Activity Based Costing was implemented in a convenience sample of nine geographically and socioeconomically diverse GP practices. A survey was used to collect cost data for the previous year, and clinical and administrative personnel kept activity records for a 2-week period. Organizational elements that contribute to lower costs include shorter appointment lengths, increased use of administrative and reception personnel, reduced working hours for the practice manager and practice nurse, and the employment of health-care assistants for adult immunizations. The identified expenses are less than the payments at all practices.

The funding for immunization efforts recived was greater than the expenditures at the practices covered. Several organizational variables that have an influence on program delivery costs and might be altered have been discovered.
