Although legislation permits New Brunswick pharmacy professionals to administer a wide range of immunizations, public funding for these services is currently limited to immunizations against influenza and COVID-19 and was recently extended to include pneumococcal immunization (Pneu23) in individuals aged 65 years or older. We used administrative data to project health and economic outcomes associated with the current Pneu23 program and with extension of public funding to include: 1) younger adults aged 19 years or older in the Pneu23 program, and 2) tetanus boosters (Td/Tdap).

Two model scenarios were compared: a Physician-Only model in which physicians remain the only practitioners to administer publicly funded Pneu23 and Td/Tdap, and a Blended model in which this service is also provided by pharmacy professionals. Immunization rates by practitioner type were projected based on physician billing data accessed via the New Brunswick Institute for Research, Data and Training in conjunction with trends observed with influenza immunization by pharmacists. These projections were used along with published data to estimate health and economic outcomes under each model.

Public funding of Pneu23 (65+), Pneu23 (19+) and Td/Tdap (19+) administration by pharmacy professionals is projected to yield increased immunization rates and physician time savings compared with the Physician-Only model. Public funding of Pneu23 and Td/Tdap administration by pharmacy professionals in those aged ≥19 years would result in cost savings, owing primarily to productivity losses avoided in the working age population.

Increased immunization rates, physician time savings and cost savings may be realized if public funding were extended to include administration of Pneu23 in younger adults and Td/Tdap, by pharmacy practitioners.
