The majority of us had paid little attention to the development of a new strain of coronavirus in China. However, on 4 January 2020 Justin Stebbing, Professor of Cancer Medicine and Oncology at Imperial College, London, wrote an email to Niall Ferguson mentioning stories he had heard of strange cases of pneumonia emanating from Wuhan, China. He then began writing daily notes. Professor Stebbing tracks the development Covid-19 over the course of this unforgettable year, navigating his way through the infodemic of misinformation regarding the virus. From the early onset of the virus when he tracked its spread, the impact on individual countries and the introduction of contact tracing through to the development of vaccines, their clinical trials and eventual rollout, and their efficacy against the newly developing variants.
