COVID-19: A History: by Jacalyn Duffin, Montreal and Kingston, McGill-Queen's University Press, 2022, 232 pp., CAN $27.95 (cloth), ISBN 978-0-2280-1411-9

Duffin estimates that 55 vaccines were in development and some, such as the mRNA vaccines developed by Pfizer-BioNTech and Moderna, were entirely novel. These are minor quibbles since Duffin works to her strengths as an historian and maintains a clear focus on the science, medicine, and public health responses to COVID-19. Duffin then turns to the science and medicine of COVID, including topics like testing, treatments, and the development of vaccines. [Extracted from the article]
