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.

Jim Downs (Gettysburg College) joins the Infectious Historians to talk about his recent book. The conversation begins with epidemiology and its origins, focusing on the 18th century military bureaucracy and the production of scientific knowledge in venues associated with slavery, prisons, the colonies and war. Jim follows the people who produced this knowledge - but emphasizes the voices of the marginalized groups who are an inherent part of this story. The last part of the interview is a discussion of Jim’s public-facing work and some of the issues that such work might encounter.

Sara Carr (Northeastern University) joins the Infectious Historians for a conversation about her work on redesigning urban space in response to a pandemic. The discussion begins with a survey of the major changes in urban landscapes in the US over the past two centuries. Sara presents the epidemics she covers - ranging from cholera to urban blight - and talks about the speed in which changes might be expected to occur. The differential impact of diseases among class and residency status comes up in several contexts, and Sara discusses what changes might happen in urban space as a result of the Covid pandemic.

Maria Spyrou (University of Tübingen) and Phil Slavin (University of Stirling) join Merle and Lee to discuss their recent Nature publication on the source of the Black Death. After quickly covering the basics of paleogenetics and the history of the Black Death(!), the conversation moves on to the article itself and highlights its importance while also offering a “behind-the-scenes” look at how the research was planned and conducted. In the later part of the episode, Maria and Phil reflect on their collaboration over the past several years as well as on interdisciplinarity, its challenges and its potential.

Anjuli Raza Kolb (University of Toronto) joins Merle and Lee to discuss “Epidemic Empire”, her recent book on the history behind the metaphor of the “terrorism epidemic”. The conversation covers the development of the idea of insurgent violence as an epidemic in the nineteenth century, touching on imperialism and colonialism, particularly from a British perspective. Anjuli traces the development of the metaphor chronologically, with several stops along the way, until Covid. Among others, Anjuli examines discourse about Muslims and infectious disease, and several transition points - such as the Haiti Revolution and the Algerian Independence Movement, as well as AIDS and 9/11.

Adam Izdebski (Max Planck Institute for the Science of Human History) joins the Infectious Historians to discuss his work at the frontier between pollen and disease, and in particular in light of his recent work analyzing pollen from the time of the Black Death. The conversation begins with an introduction to palynology (pollen analysis) and its limitations. Adam discusses fieldwork as well as a few examples for what pollen can offer us before turning to his research and what his large meta-analysis of pollen sites across Europe found about the Black Death. Adam also touches upon the potential of interdisciplinary work as well as his outreach initiatives, including his project of getting involved with policymaking.

Suman Seth [https://sts.cornell.edu/suman-seth]  joins Merle and Lee to talk about his work on medicine in the British colonies during the 18th century and how it changed as people learned about tropical diseases. Suman begins by providing background on how medicine was practiced in Britain and in the colonies, alongside how new generations learned about tropical diseases over time. He then discusses how people new to colonies were “seasoned” to acclimate them to tropical diseases along with differences in this impact on colonizers, soldiers, and the enslaved among others. At the end, Suman describes how these changes shaped the development of ideas of race and racial thinking.

Jennifer Hughes joins Merle and Lee to discuss her work on empire, society and church in 16th century Mexico. After Jennifer sets up the conversation with some background, the discussion focuses on the growth of the Catholic church in Mexico through the Spanish Empire against a backdrop of periodic epidemic disease, examining changes through both imperial and indigenous perspectives. The discussion covers themes such as the economic impact of disease, conversion to Christianity, and the indigenous response to cataclysmic epidemics. Jennifer also presents the range of attitudes and responses on the Spanish side.

Claas Kirchhelle (University College Dublin) and Samantha Vanderslott (Oxford University) talk to Merle and Lee about the development and history of public health laboratories and how they worked (or didn’t) during Covid. After first discussing what a public health lab is and how they work, they speak about when they were created in a few countries around the world and how they have developed historically. Claas and Sam note the role of public and private labs together and the key role of Swine Flu in 2009 in how this shaped public health then and during Covid. They also point out the tensions between centralized big data goals and the need for local public health facilities and aims. At the end, Claas and Sam suggest how Covid might be used to shape better outcomes in the future with a greater place for social scientists in future planning.

Merle and Lee meet in person at Princeton University, where they both attended the first in person conference for over two years. The short episode begins with some reflections on Covid and its effects now that things are slowly returning to their pre-Covid state. The conversation continues towards thinking about the podcast’s past year, and Merle and Lee raise several ideas and suggestions they hope to pursue in the podcast’s third year.
