The Evolution of Pharmacist Administered Vaccinations in Australia: A Narrative Review of Legislation and Regulatory Documents

Background: Since 2014, all Australian jurisdictions have progressively amended legislation to authorise pharmacists to administer vaccines, evolving from restricted pilots to an essential public health pillar. Objective: This review analyses the longitudinal evolution of pharmacist-administered vaccinations (PAVs), documenting changes in authorised vaccines, age eligibility, and regulatory frameworks across all Australian jurisdictions. Methods: A retrospective review of Australian jurisdictional legislation, regulations, and policy documents was undertaken. Searches included official legislative registers, Government Gazettes, Health Department protocols, and professional guidance published by Pharmaceutical Society of Australia (PSA) and The Pharmacy Guild of Australia between 2014 to 2026. Documents were independently reviewed by five authors, followed by secondary verification and consensus-based adjudication to resolve discrepancies and confirm findings. Results: PAVs scope was expanded from a single influenza pilot in 2014 to include over 21 vaccine-preventable diseases by 2026. The COVID-19 pandemic catalysed rapid reform, leading to the standardisation of age eligibility (largely ≥5 years). A landmark milestone occurred in 2025 when South Australia enabled pharmacists to administer any vaccine within their professional scope. Conclusion: Legislative reforms have significantly enhanced vaccine accessibility. However, jurisdictional fragmentation persists. National harmonisation, using a competency-based model similar to South Australia, is recommended to streamline delivery and optimise public health outcomes.
