Paula Larsson (University of Oxford) comes on the new Infectious Historians episode to talk about her work on anti-vaccination movements. The conversation begins with an overview of vaccines before moving into vaccine hesitancy and anti-vaccination. Paula explores the similarities in anti-vaccination movements and their arguments over the past two centuries, while drawing parallels to famous recent cases such as the MMR vaccine and its false links to autism and the Covid vaccine. Near the end, Paula discusses her public engagement work, which she has pursued through multiple pathways.
