Background
Norway and Sweden picked two different ways to mitigate the dissemination of the SARS-CoV-2 virus. Norway introduced the strictest lockdown in Europe with strict border controls and intense virus tracking of all local outbreaks while Sweden did not. That resulted in 477 COVID-19 deaths (Norway) and 9737 (Sweden) in 2020, respectively.
Methods
Weekly number of COVID-19 related deaths and total deaths for 2020-22 were collected as well as weekly number of deaths for 2015-19 which were used as controls when calculating excess mortality. During the first 12-18 months with high rate of virus transmission in the society, excess mortality rates were used as substitute for COVID-19 deaths. When excess mortality rates later turned negative because of mortality displacement, COVID-19 deaths adjusted for bias due to overreporting were used.
esults
There were 17521 COVID-19 deaths in Sweden and 4272 in Norway in the study period. The rate ratio (RR) of COVID-19 related deaths in Sweden vs. Norway to the end of week 43, 2022, was 2.11 (95% CI 2.05-2.19). RR of COVID-19 related deaths vs. excess number of deaths were 2.5 (Sweden) and 1.3 (Norway), respectively. RR of COVID-19 deaths in Sweden vs. Norway after adjusting for mortality displacement and lockdown, was 1.35 (95% CI 1.31-1.39), corresponding to saving 2025 life in Norway. If including all deaths in 2022, RR=1.28 (95% CI 1.24-1.31).
Conclusions
Both COVID-19 related mortality and excess mortality rates are biased estimates. When adjusting for bias, mortality differences declined over time to about 30% higher mortality in Sweden after 30 months with pandemics and at the cost of 12 million € per prevented death in Norway.
9 November 2023 Seminar: Age Patterns of Mortality Across Influenza Pandemics
For the penultimate Pandemics & Society Seminar of our Fall 2023 series, we are pleased to welcome Lauren Steele (University of Queensland). The seminar will be held on Thursday, 9 November at the normal time (1600 CET). More information about our speaker and the presentation is below. You can sign up for email notifications about the seminar series, including the Zoom details, here.
Abstract
During the 1918 influenza pandemic, individuals aged ~15-40 years of age were more susceptible to severe disease and death. Similar age patterns have been recorded during the 1957 and 1968 influenza pandemics, however no geographically wide-scale age curves have ever been calculated for these pandemics. Data from at least five countries will be analysed to construct age curves to identify age-related mortality during the influenza pandemics of the 20th century. Data will be collected from vital statistics and the Human Mortality Database. To further elucidate the role of age in influenza disease outcomes during pandemics, lungs taken from young adults (aged 17-30 years) who died of influenza-like illnesses during pandemic years will be analysed using a spatial transcriptomics assay to determine gene expression at the moment of death. These data will inform on why younger age groups are uniquely susceptible to severe disease during influenza pandemics.
About the Speaker
Lauren Steele is a second-year PhD candidate at the University of Queensland, Australia. She is completing her thesis on host factors which influence disease outcomes during past influenza pandemics to inform on future influenza pandemic preparedness measures.
Har forskere tatt helt feil om spanskesyken i 1918?
Nå har en gruppe forskere i USA gransket 369 skjeletter etter personer som døde i årene før og etter spanskesyken.
Det var ikke de unge med god helse som døde, konkluderer forskerne. En av disse er Amanda Wissler. Hun var gjesteforsker i vårt 2022-23 CAS-prosjekt Social Science Meets Biology | CAS (cas-nor.no)
De unge som døde under influensapandemien i 1918 og 1919, var allerede svekket av sykdommer som tuberkulose.
Det var de mest sårbare i samfunnet som gikk bort. Ikke de friske. Disse funnene stemmer godt med vår egen forskning.

Abstract
The effectiveness of vaccination against severe COVID-19 infection and mortality is well documented, but there are inequalities in both vaccination uptake and COVID-19 mortality. Understanding whether more equal vaccination uptake might reduce socioeconomic inequalities in COVID-19 mortality is necessary for planning for future pandemics. Limited evidence available suggests that COVID-19 vaccination may have reduced inequalities in mortality. However, existing studies typically employ data covering a short time series and do not explicitly model inequalities. Using national data from the first recorded deaths through to December 2022, this study investigates whether the national vaccination program in England reduced inequalities in COVID-19 mortality associated with area-level deprivation. Descriptive analyses demonstrated that, though vaccination uptake was generally high, there was a widening gap between the most and least deprived areas in England in uptake by dose. New mortality inequality gradually declined as vaccination uptake and doses increased, and remained low throughout 2022. However, cumulative mortality inequalities rapidly grew from the start of the pandemic continued to grow throughout the entire period of observation. We estimate that more equitable vaccine uptake may have reduced, but not eradicated deprivation-based inequalities. We argue that preparation for future pandemics should include a comprehensive strategy for minimising deprivation-based inequalities.

19 October 2023 Seminar: The Grenfell Mission and the 1918 influenza pandemic in Labrador
For the sixth Pandemics & Society Seminar of our Fall 2023 series, we are pleased to welcome our colleague Uddhav Khakurel (PANSOC). The seminar will be held on Thursday, 19 October at the normal time (1600 CEST). More information about our speaker and the presentation is below.

Abstract
Labrador, part of the British Empire at the time but under the control of the Dominion Government of Newfoundland, was one of the most severely affected regions in the world during the 1918 influenza pandemic, with mortality ranging from 1 to 78 percent within communities. During the time of the pandemic, healthcare needs in the southern two-thirds of Labrador were provided by the Grenfell Mission, led by Dr. Wilfred Grenfell. This study explores the role played by the Grenfell Mission during the 1918 influenza pandemic. In addition, this analysis seeks to deepen our understanding of the factors that influenced the Mission’s response during the pandemic. This study was conducted using archival and secondary sources. Historical archives were collected from the digital archives of the Memorial University of Newfoundland and Yale University between the period of 1918 to 1959. Our findings suggest that despite the long presence of the Grenfell Mission from 1893 in Labrador, it faced a formidable challenge in providing health care during the influenza pandemic. The Mission had only one doctor and two nurses for 800 square miles. Their work in Labrador was further constrained by geographical isolation, weather conditions, shortage of healthcare workers, and its relationship with the Newfoundland Government. These factors help to explain the high level of heterogeneity in mortality within communities in Labrador.

What can historians in the history of medicine and health offer when a crisis in medicine occurs?
By Vibeke Narverud Nyborg (Associated Professor 2 at PANSOC, with research financed by University of South-Eastern Norway).
The conference from the European Association in the History of Medicine and Health (EAHMH) has just taken place at the University of Oslo. The theme for this conference was “Crisis in Medicine and Health,” a timely theme considering the recent experiences with COVID-19. However, being a conference in history most sessions drew on experiences occurring far earlier than the last pandemic, leaving to the participants to also reflect upon how historians can apply their research to the present and what the role and responsibilities historians have when a new crisis in medicine and health occurs.
Firstly, historians in medicine and health, like most other people and scholars do not agree upon how their research can be applied and to what extent historians have a role and a responsibility to act and share their knowledge of past events in time of crisis. These are hence my own reflections based on my own experiences together with insight gained through this recent conference and discussions with colleagues presenting here.
Historians work with the past. When it comes to dealing with crisis this can be considered a blessing, as both time and space give us the necessary space to reflect and see a broader picture when dealing with the actual crisis. The past and past events differ from the present despite some trajectories and pathways to some extent appears remarkably similar. This leads us to the question; can we learn anything from history? Is it possible to draw knowledge from historical lessons? Historians disagree on this too. While some will deny the possibility of any lessons to be learned other simply state that it is impossible not to take advantage of history, as we are all results of the historical context and past society is based upon.
My view in this is that lessons cannot be drawn from history in the sense that 1 = 1, that is this event happened before, therefor the same event will lead to the same consequences again. The past is different, knowledge, people and society develop. However, historical knowledge will contribute to see patterns, contribute with significant contextual framing which can make us point to consequences of decisions, stories that became invisible, people not heard, different responses to the same medical threats and risks taken by individuals and/or society to cope with the threats opposed by medical and health issues. Historians can also contribute with reflections concerning consequences in the aftermath of crisis, because they are trained in understanding how continuity and change appear and what factors that can be seen as plying into what prevails and what changes after specific events.
Dealing with past epidemics and pandemics in my research, working together with knowledgeable colleagues in an interdisciplinary team and living through a medical crisis such as COVID-19, my experience is that historians have a lot to offer concerning knowledge about past medical crisis, if people are willing to listen. We can use this knowledge to contribute with understanding and contextualizing, framing a current crisis within a broader picture. What we cannot do is to predict the future based on our past knowledge, which often seem to be what people expect. Historians deal with the past, we do not predict for the future.
The Centre for Research on Pandemics and Society (PANSOC) is quite unique in its approach to investigate and research historical epidemics and pandemics, exploring societal consequences, both short and long term on past pandemics. The variety of approaches involving, social inequalities, disparities, economic, minorities, legislative, political and individual experiences on medical crisis give a unique knowledge relevant to the present as well as future pandemics if we do not let these experiences be part of the crisis memory gap, but continuously contribute to claim our relevance and advocate the knowledge we gain from our research to other academics, politicians and policy makers.

12 October 2023 Seminar: Cholera & Spanish Flu in the Philippines
For the next Pandemics & Society Seminar of our Fall 2023 series, we are pleased to welcome Professor Francis Gealogo (Ateneo de Manila University). The seminar will be held on Thursday, 12 October at the normal time (1600 CEST). More information about our speaker and the presentation is below.

Abstract
The Cholera Epidemic of 1903-05 and the 1918 influenza pandemic were one of the most virulent epidemics ever to hit the American-occupied Philippines. The impact of the contagion was felt unevenly by the population of the islands, with some populations becoming more vulnerable to the disease compared to others.
The presentation analyzes the environmental and ecological dimensions of the spread of the disease, and the attempts by different sectors to contain the epidemic, or mitigate its impact for those already affected by the outbreak. Specifically, the paper will assess the pandemics as experienced in prison populations, leper colonies, and military camps as examples of confined populations and rural ethnic communities, urban and suburban communities as examples of unconfined populations. The official government actions as well as the people’s perception about the pandemics in these population types will also be analyzed in order to advance the evaluation on the social dimension in the history of this pandemic from the prism of medical and demographic history. Finally, the paper will present the Philippine experience during the cholera and influenza pandemic and contextualize them as part of the Philippine colonial experience under the United States.
