    Briefing: Vaccines, Variants, and Ventilation A Briefing on Recent Scientific Literature Focused on SARS-CoV-2 Vaccines and Variants, Plus the Effects of Ventilation on Virus Spread Dates of Search: 01 January 2021 through 05 July 2021 Published: 22 July 2021 This document synthesizes various studies and data; however, the scientific understanding regarding COVID-19 is continuously evolving. This material is being provided for informational purposes only, and readers are encouraged to review federal, state, tribal, territorial, and local guidance. The authors, sponsors, and researchers are not liable for any damages resulting from use, misuse, or reliance upon this information, or any errors or omissions herein. INTRODUCTION Purpose of This Briefing • Access to the latest scientific research is critical as libraries, archives, and museums (LAMs) work to sustain modified operations during the continuing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. • As an emerging event, the SARS-CoV-2 pandemic continually presents new challenges and scientific questions. At present, SARS-CoV-2 vaccines and variants in the US are two critical areas of focus. The effects of ventilation-based interventions on the spread of SARS-CoV-2 are also an interest area for LAMs. This briefing provides key information and results from the latest scientific literature to help inform LAMs making decisions related to these topics. How to Use This Briefing: This briefing is intended to provide timely information about SARS-CoV-2 vaccines, variants, and ventilation to LAMs and their stakeholders. Due to the evolving nature of scientific research on these topics, the information provided here is not intended to be comprehensive or final.

A Predictive Modelling Framework for COVID-19 Transmission to Inform the Management of Mass Events Claire Donnat Freddy Bunbury Department of Statistics Department of Plant Biology University of Chicago, Chicago, USA Carnegie Institution for Science, Stanford, USA [email protected] [email protected] Jack Kreindler Filippos T. Filippidis School of Public Health School of Public Health Imperial College, London, UK Imperial College, London, UK [email protected] [email protected] Austen El-Osta Tõnu Esko Matthew Harris School of Public Health Institute of Genomics School of Public Health Imperial College, London, UK University of Tartu, Tartu, Estonia Imperial College, London, UK [email protected] [email protected] [email protected] Abstract Modelling COVID-19 transmission at live events and public gatherings is essential to evaluate and control the probability of subsequent outbreaks. Model estimates can be used to inform event organizers about the possibility of super-spreading and the predicted efficacy of safety protocols, as well as to communicate to participants their personalised risk so that they may choose whether to attend. Yet, despite the fast-growing body of literature on COVID transmission dynamics, current risk models either neglect contextual information on vaccination rates or disease prevalence or do not attempt to quantitatively model transmission, thus limiting their potential to provide insightful estimates.

  • Early History of Infectious Disease 
    © Jones and Bartlett Publishers. NOT FOR SALE OR DISTRIBUTION CHAPTER ONE EARLY HISTORY OF INFECTIOUS 1 DISEASE Kenrad E. Nelson, Carolyn F. Williams Epidemics of infectious diseases have been documented throughout history. In ancient Greece and Egypt accounts describe epidemics of smallpox, leprosy, tuberculosis, meningococcal infections, and diphtheria.1 The morbidity and mortality of infectious diseases profoundly shaped politics, commerce, and culture. In epidemics, none were spared. Smallpox likely disfigured and killed Ramses V in 1157 BCE, although his mummy has a significant head wound as well.2 At times political upheavals exasperated the spread of disease. The Spartan wars caused massive dislocation of Greeks into Athens triggering the Athens epidemic of 430–427 BCE that killed up to one half of the population of ancient Athens.3 Thucydides’ vivid descriptions of this epidemic make clear its political and cultural impact, as well as the clinical details of the epidemic.4 Several modern epidemiologists have hypothesized on the causative agent. Langmuir et al.,5 favor a combined influenza and toxin-producing staphylococcus epidemic, while Morrens and Chu suggest Rift Valley Fever.6 A third researcher, Holladay believes the agent no longer exists.7 From the earliest times, man has sought to understand the natural forces and risk factors affecting the patterns of illness and death in society. These theories have evolved as our understanding of the natural world has advanced, sometimes slowly, sometimes, when there are profound break- throughs, with incredible speed. Remarkably, advances in knowledge and changes in theory have not always proceeded in synchrony. Although wrong theories or knowledge have hindered advances in understanding, there are also examples of great creativity when scientists have successfully pursued their theories beyond the knowledge of the time.
