Associate Professor Katie Attwell has supported Australian state and federal governments with vaccine communications, developing interventions for vaccine confidence, and policies for routine and COVID-19 vaccinations, as well as researching vaccination policymaking in the United States, the United Kingdom, Italy, France, Bangladesh, and Malaysia. Her technical expertise lies in vaccination social science and vaccination policy. She focuses on ways to share this expertise with global policymakers, to support the growth of vaccination social science, to build the capacity of vaccination social science researchers, and to assist countries in responding to challenges to their immunisation programs or the rollout of new vaccines.
