Pregnant women and their interests have been underrepresented in health research. Little is known about issues relevant to women considering research participation during pregnancy. We performed in-depth interviews with 22 women enrolled in either one of two trials sponsored by the National Institutes of Health to assess the safety and immunogenicity of the H1N1 vaccine during pregnancy. Three themes characterized women’s decisions to participate in research: they valued early access to the vaccine, they perceived a safety advantage when participating (...) in research, and they wanted to help advance scientific knowledge. However, there were also some considerations that would disincline them to participate in research—for instance, a significant risk of maternal or fetal harm, the presence of a placebo arm in a study, or a requirement to significantly change planned therapy or behavior. Pregnant women who participated in the H1N1 vaccine trials viewed research favorably, citing its advantages over standard clinical care. These findings emphasize that access to benefit should guide policy for including pregnant women in research. (shrink)

The emergence of the 2009 H1N1 virus pandemic was unexpected, since it had been predicted that the next pandemic would be caused by subtype H5N1. We also had to learn that a pandemic does not necessarily require the introduction of a new virus subtype into the human population, but that it may result from antigenic shift within the same subtype. The new variant was derived from human and animal viruses by genetic reassortment in the pig, supporting (...) the concept that this animal is the mixing vessel for the generation of new human influenza viruses. Although it is generally believed that the 2009 outbreak was mild, there have been severe cases particularly among the young and the middle‐aged. Pathogenicity and host range are determined to a large extent by the polymerase, the haemagglutinin and the NS1 protein of influenza A viruses. There is evidence that mutations of these proteins may change the pathogenicity of the new virus. (shrink)

Hemagglutinin is a major virulence factor of influenza viruses and plays an important role in viral pathogenesis. Analysis of amino acid changes, epitopes’ regions, glycosylation and phosphorylation sites have greatly contributed to the development of new generations of vaccine. The hemagglutinins of 10 selected isolates, 8 of 2010 and 2 of 2013 samples were sequenced and analyzed by several bioinformatic softwares and the results were compared with those of 3 vaccine isolates. The study detected several amino acid changes related (...) to altered epitopes’ sites, modification sites and physico-chemical properties. The results showed some conserved modification sites in HA structure. This study is the first analytical research on isolates obtained from Shiraz, Iran, and our results can be used to better understand the genetic diversity and antigenic variations in Iranian and Asian H1N1 pathogenic strains.

Here I present a list of the most important facts related to the approval and implementation of the influenza virus A (HINl) vaccine trial in Costa Rica. I also discuss some of the ethical conflicts involved and suggest some possible solutions.

Epidemics that were probably influenza have been reported throughout recorded history. There were 13 fairly severe epidemics during the 18th century and 12 during the 19th century. Probably 8 of these 25 were influenza pandemics. In the 20th century there have been 4 pandemics (1918/19, 1957/58, 1968/69 and 1977) due to the emergence of new subtypes of influenza A virus. The great pandemic of 1918/19 caused an estimated 20 million deaths. Between pandemics usually there have been epidemics (...) of varying severity at intervals of one to three years and a trickle of sporadic cases every winter. The morbidity and mortality rates have varied greatly from epidemic to epidemic and from place to place during the same epidemic. Generally the morbidity has been lowest in people over 60 years of age, but, except for 1918/19, the mortality has been predominantly in old people. The epidemic behaviour of influenza has been so erratic and difficult to understand that there are still a few scientists who consider that extraterrestrial influences operate. These views are not taken seriously by most virologists but there are puzzling aspects of influenza that are not yet understood. (shrink)

Pandemics challenge the law and often highlight its strengths or expose its limits. The novel strain of influenza A virus that emerged in the spring of 2009 and rapidly spread around the globe was no exception. The H1N1 pandemic prompted the first significant application of a number of international legal and policy mechanisms that have been developed in the last decade to respond to this kind of event. Furthermore, it presented a considerable test for public health systems at (...) all levels, from global to local.Although initial predictions forecasting high morbidity and mortality from this virus overestimated its eventual impact, the human toll of the pandemic was nevertheless significant. The World Health Organization reported approximately 1.5 million people were infected worldwide in 214 countries, resulting in over 25,000 confirmed deaths, but the actual health impact of the outbreak was certainly much higher.

The detection and spread of pandemic 2009 H1N1 influenza in the United States led to a complex and multi-faceted response by the public health system that lasted more than a year. When the first domestic case of the virus was detected in California on April 15, 2009, and a second, unrelated case was identified more than 130 miles away in the same state on April 17, 2009, the unique combination of influenza virus genes in addition to its (...) emergence and rapid spread at the end of the typical Northern Hemisphere influenza season suggested the potential for a high morbidity, high mortality event. In response, federal, state, and local public health officials conducted epidemiologic investigations with federal and state laboratory support to help to determine the scope of the H1N1 pandemic. On April 26, the Secretary of the U.S. Department of Health and Human Services declared a public health emergency that was renewed through June 23, 2010. The pandemic that ensued tested virtually every aspect of U.S. public health preparedness and response systems, from laboratory capabilities and capacities to social distancing plans. (shrink)

ArgumentScientific uncertainty is fundamental to the management of contemporary global risks. In 2009, the World Health Organization declared the start of the H1N1 Influenza Pandemic. This declaration signified the risk posed by the spread of the H1N1 virus, and in turn precipitated a range of actions by global public health actors. This article analyzes the WHO's public representation of risk and examines the centrality of scientific uncertainty in the case of H1N1. It argues that the WHO's (...) risk narrative reflected the context of scientific uncertainty in which it was working. The WHO argued that it was attempting to remain faithful to the scientific evidence, and the uncertain nature of the threat. However, as a result, the WHO's public risk narrative was neither consistent nor socially robust, leading to the eventual contestation of the WHO's position by other global public health actors, most notably the Council of Europe. This illustrates both the significance of scientific uncertainty in the investigation of risk, and the difficulty for risk managing institutions in effectively acting in the face of this uncertainty.

The virulence of a virus is determined by its ability to adversely affect the host cell, host organism or population of host organisms. Influenza A viruses have been responsible for four pandemics of severe human respiratory disease this century. Avian species harbour a large reservoir of influenza virus strains, which can contribute genes to potential new pandemic human strains. The fundamental importance of understanding the role of each of these genes in determining virulence in birds and humans was (...) dramatically emphasised by the recent direct transmission of avian influenza A viruses to humans, causing fatal infection but not community spread. An understanding of the factors involved in transmission between avian and mammalian species should assist in the development of better surveillance strategies for early recognition of influenza A virus strains having human pandemic potential, and possibly in the design of anti‐viral strategies.

According to the World Health Organisation, three to five million individuals are infected by influenza, and around 250,000 to 500,000 people die of this infectious disease worldwide. Influenza epidemics pose a serious public health threat. Moreover, graver dangers are encountered with influenza subtypes against which there is little or no preexisting human immunity. Such subtypes of influenza have the potential to cause devastating epidemics. Thus, enhancing surveillance systems for the purpose of detecting influenza epidemics in (...) an early stage can quicken response times and save millions of lives. This paper presents three adapting intelligence models: support vector machine regression, artificial neural network using particle swarm optimisation, and our intelligent time series to predict influenza epidemics. The novelty of the current study is that it proposes a new intelligent model to predict influenza outbreaks. The INTS model combines clustering with a time series model to enhance the prediction of influenza outbreaks. The innovation of our proposed model integrates the results obtained from the existing weighted exponential smoothing model with centroids obtained from clustering. We developed a surveillance system for influenza epidemics using Google search queries. The current research is based on a weighted version of the Center for Disease Control and Prevention influenza-like illness activity level obtained from the Center for Disease Control and Prevention data, as well as query data obtained from the Goggle search engine in the USA. The influenza-like illness data was collected from January 4, 2009, to December 27, 2015, stretching across a total time span of 312 weeks. Google Correlate was used to select search queries related to influenza epidemics. In total, 100 search queries were obtained from Google Correlate, 10 of which were better and more relevant search queries selected in this study. The model was evaluated using online Google search queries collected from Google Correlate. Standard measure performance MSE, RMSE, and MAE were employed to estimate the results of the proposed model. The empirical results of the INTS model showed MSE = 0.003, RMSE = 0.036, and MAE = 0.0185, indicating that the errors of the proposed model are very limited. A comparative model of predicting results between the INTS model, alternative Google Flu Trend, and autoregression with Google search data is also presented. The proposed model outperformed the existing models. (shrink)

The 2009 pandemic of influenza A (H1N1) was relatively mild, but a subsequent outbreak of pandemic influenza could be much worse. According to projections from the Department of Health and Human Services, the potential health consequences of a severe (1918-like) influenza pandemic in the United States could be literally overwhelming: up to 1.9 million deaths; 90 million people sick; 45 million people needing outpatient care; 9.9 million people hospitalized, of whom 1.485 million would need treatment in (...) an intensive care unit (ICU); and 742,500 patients needing mechanical ventilators. Even a less cataclysmic, moderate pandemic (like 1958 or 1968) would result in 209,000 deaths; 90 million people sick; 45 million people needing outpatient care; 865,000 people hospitalized, of whom 128,750 would need treatment in an ICU; and 64,875 patients needing mechanical ventilators.

After viral entry into the cell, the nuclear envelope poses a major cellular barrier that needs to be overcome upon adaptation of highly pathogenic avian influenza viruses (HPAIV) to the new host. To ensure efficient viral transcription and replication in the nucleus of the host cell, the viral polymerase complex of avian influenza viruses needs to switch from recognition of avian to mammalian components of the nuclear import machinery. Recent evidence suggests that influenza viruses have evolved different (...) mechanisms to utilize importin‐α isoforms as components of this machinery, bridging pre‐ and post‐nuclear import on both sides of the nuclear envelope.

In a number of membrane-bound viruses, ion channels are formed by integral membrane proteins. These channel proteins include M2 from influenza A, NB from influenza B, and, possibly, Vpu from HIV-1. M2 is important in facilitating uncoating of the influenza A viral genome and is the target of amantadine, an anti-influenza drug. The biological roles of NB and Vpu are less certain. In all cases, the protein contains a single transmembrane α-helix close to its N-terminus. Channels (...) can be formed by homo-oligomerization of these proteins, yielding bundles of transmembrane helices that span the membrane and surround a central ion-permeable pore. Molecular modeling may be used to integrate and interpret available experimental data concerning the structure of such transmembrane pores. This has proved successful for the M2 channel domain, where two independently derived models are in agreement with one another, and with solid-state nuclear magnetic resonance (NMR) data. Simulations based on channel models may yield insights into possible ion conduction and selectivity mechanisms. BioEssays 20:992–1000, 1998. © 1998 John Wiley & Sons, Inc. (shrink)

For last couple of years, the subcontinent of India has witnessed a number of influenza epidemic outbreaks. History reveals influenza epidemic to be a constant but neglected companion of India. Considering the repeated occurrences of the event on Indian soil, including influenza A H1N1 after 2009-10 pandemic event, a check to the planning measures has been done at national level. A literature survey on the initiative measures, planning accomplishments etc. reveals that it is only after the (...) emergence of A H5N1, national health authorities have began planning efforts to mitigate and respond to influenza outbreaks. This paper outlines the evolution of Indian pandemic planning that can be traced in the research literature, summarize the accomplishments, and explain the importance of pandemic planning in India. Pandemic influenza, as it is commonly known, emerges, evolves, attacks, and sways a large part of world declaring public health emergency in a short span. Several outbreak events such as SARS, Avian influenza A H5N1, and H1N1 have demonstrated the need of international concern for public health emergency and had established the value of planning in advance. Preparedness planning in India is found to be at its nascent stage and it needs further improvement at multiple aspects to tackle the future public health crises, to rectify ethical failures.

As a member of the National Science Advisory Board for Biosecurity, I was involved in early deliberations about the appropriateness of publishing this avian influenza research when manuscripts were referred to us from two scientific journals during their review process, via the U.S. government. As described by David Resnik in this issue, we grappled with benefits and risks, and in our initial, unanimous decision recommended limited publication, alerting the world to the possibility of evolved transmissibility in these viruses but (...) with redaction of the exact genetic mutations that would enable anyone skilled in the art to synthesize these potentially dangerous viruses. However, after additional discussion, both internal and external to the board, we were asked to reconsider the situation, and this time a majority voted in favor of full publication. I was one of the minority that opposed full publication. Resnik points to the difficulties of performing a formal risk‐benefit assessment without the means of quantifying these two terms and suggests application of reasoning based on the precautionary principle instead. This makes sense. But there are three other issues that should be highlighted. (shrink)

The first of these is not a single disease but a group of three: ‘all the clinical and epidemiological evidence described by Thucydides’ ‘can be attributed to infection with influenza virus complicated by a toxin-producing strain of noninvasive staphylococcus’ . This initial analysis is in fact supplemented by bullous impetigo in an attempt to explain the marked skin symptoms which are not ascribable to the other two diseases: streptococci produce flushes of the skin that end in desquamation – something (...) which Langmuir et al. admit T would have described if present.

Scholars have argued that the beginning of virology can be dated from the end of the 19th century: the discovery that some infectious agents could pass through ultrafilters produced a criterium to distinguish ultrafilterable viruses from infectious agents that are not filterable, e.g. bacteria. A filterable agent, claimed to be the cause of human influenza, was isolated in 1933. It will be argued in this paper, however, that the influence of a bacteriological paradigm on influenza research in the (...) first half of the twentieth century was very powerful. Until the late 1940s influenza viruses were studied as infectious entities which, although filterable, were conceived of as analogous to bacteria. It was assumed that filterable viruses which infected animals were a kind of ultrabacteria. According to the bacteriological paradigm the assumed dependence of the filterable viruses on living cells was easy to account for. The second half of the 1940s saw the 'modern concept of virus' begin to be applied to the influenza viruses. Influenza vaccinations in 1946 did not appear to provide protection, from which it was concluded that the influenza virus is very variable. Furthermore, in 1946 and 1947 experimental studies were published, which indicated that the influenza virus may go through an eclipse during its multiplication: it disappears as an infectious agent. Viewed from this perspective, it was only by the second half of the 1940s that research on the influenza virus became emancipated from the bacteriological paradigm. (shrink)

Seasonal influenza poses a significant public health risk in many countries worldwide. Lower immunity and less influenza virus circulating during the pandemic has resulted in a significant increase in cases since the lifting of COVID-19 restrictions in 2022. The seasonal influenza vaccine offers effective protection and is safe for use in large numbers of the population. This article asserts that a moral obligation to vaccinate against influenza can be understood as an Institutional Duty of Rescue. The (...) traditional understanding of the Duty of Rescue encounters issues with force and scope, making it difficult to apply to rescue cases in general, as well as being overdemanding for the individual agent. An Institutional view of the Duty of Rescue addresses these difficulties, looks at the wider context of rescue and leaves room for discussion on collective, preventative rescue measures. This makes the concept well suited to supporting a moral obligation to vaccinate against influenza as part of a collective effort on the part of institutional organisations. (shrink)

In reviewing 50 years of personal research on influenza, I have journeyed, literally and figuratively, from an army camp epidemic in Fort Monmouth NJ in 1947 to a (literal and figurative) Valhalla, where I now conduct my research. Having entered the field as a physician, I have always sought practical applications of my work, yet in every instance, such applications have led me to seek further answers in basic research as new questions arose. I entered the area of (...) class='Hi'>influenza virus genetics by the back door through an interest in the effects of corticosteroid hormones on viral replication, used the genetic approach in analyzing the morphological variation of the virus and, in so doing, exploited the finding of a linkage of high‐yield growth to spherical morphology. Today, all influenza vaccine viruses are high‐yield genetic reassortants. Subsequent study of reassortant viruses facilitated the identification and isolation of the two major antigens of the virus in antigenic hybrids and showed their differing functions in the induction of immunity. In turn, a new approach to influenza vaccination has been discovered and is presently under clinical investigation. (shrink)

Moates, Anne The prospect of a virulent human influenza pandemic causing large scale mortality and morbidity is a cause for global concern. The most likely candidate is the avian or 'bird' flu which is a strain of influenza virus named because it is found in birds. There are three groups of flu viruses, influenza A, B and C. Type A viruses are able to infect a wide variety of warm-blooded animals. B and C types are mostly confined (...) to humans. Avian influenza is caused by a Type A virus and typically affects birds' respiratory, digestive and nervous systems.[1]. (shrink)

In December 2006, Indonesia decided to stop sending influenza virus specimens to the World Health Organization’s Global Influenza Surveillance Network (GISN). Indonesia justified its actions by claiming that they were in protest of the injustice of GISN. Its actions stimulated negotiations to improve the workings of GISN by developing and implementing a more just framework for ‘sharing influenza viruses and other benefits’. These negotiations eventually led to the adoption of a new framework for virus and benefit sharing (...) in May 2011, at the World Health Assembly meeting. In this article, we critically evaluate Indonesia’s claims about the unjustness of GISN. We show that arguments based on the values of ownership, contribution and reciprocity work together to support Indonesia’s claim that it was owed an equal share in the benefits of GISN and, in turn, that GISN was unjust because of its failure to ensure this. We also use these values to evaluate the newly agreed upon framework for virus and benefit sharing. We suggest the new framework fails to give proper consideration to the values of ownership, contribution and reciprocity and, as a result, that it is fundamentally unjust. (shrink)

The threat posed by avian influenza appears to be rising, yet global and national health programs are preparing only fitfully. A lethal form of avian flu has rooted itself deeply into the poultry flocks of poor Asian countries that will have a hard time eradicating it.

All it would take to set off a raging global pandemic would be for the virus to mutate into a form that is readily transmissible among humans. Severe Acute Respiratory Syndrome garnered a great deal of public attention because it was novel and its potential for spread was unknown.

While public health ethics typically deals with issues wherein individual well-being competes with the population’s wellbeing, it also deals with competing groups’ well-being. Public health responses to the Chicago heat wave and Hurricane Katrina were strongly criticized, in part, because certain groups of people experienced far greater and longer-lasting losses compared to others. Diff erences in experience were largely due to socio-economic-political disadvantages or vulnerabilities. This article is written in light of the recent fi rst and second “waves” of the (...)

On March 11, 2020 the World Health Organization classified COVID‐19, caused by Sars‐CoV‐2, as a pandemic. Although not much was known about the new virus, the first outbreaks in China and Italy showed that potentially a large number of people worldwide could fall critically ill in a short period of time. A shortage of ventilators and intensive care resources was expected in many countries, leading to concerns about restrictions of medical care and preventable deaths. In order to be prepared for (...) this challenging situation, national triage guidance has been developed or adapted from former influenza pandemic guidelines in an increasing number of countries over the past few months. In this article, we provide a comparative analysis of triage recommendations from selected national and international professional societies, including Australia/New Zealand, Belgium, Canada, Germany, Great Britain, Italy, Pakistan, South Africa, Switzerland, the United States, and the International Society of Critical Care Medicine. We describe areas of consensus, including the importance of prognosis, patient will, transparency of the decision‐making process, and psychosocial support for staff, as well as the role of justice and benefit maximization as core principles. We then probe areas of disagreement, such as the role of survival versus outcome, long‐term versus short‐term prognosis, the use of age and comorbidities as triage criteria, priority groups and potential tiebreakers such as ‘lottery’ or ‘first come, first served’. Having explored a number of tensions in current guidance, we conclude with a suggestion for framework conditions that are clear, consistent and implementable. This analysis is intended to advance the ongoing debate regarding the fair allocation of limited resources and may be relevant for future policy‐making. (shrink)

The current COVID-19 pandemic has reactivated ancient metaphors but also initiated a new vocabulary: social distancing, lockdown, self-isolation, and sheltering in place. Terminology is not ethically neutral but reflects prevailing value systems. I will argue that there are two metaphorical vocabularies at work: an authoritarian one and a liberal one. Missing is an ecological vocabulary. It has been known for a long time that emerging infectious diseases are associated with the destruction of functioning ecosystems and biodiversity.

The asymmetric distribution of lipids, maintained by flippases/floppases and scramblases, plays a pivotal role in various physiologic processes. Scramblases are proteins that move phospholipids between the leaflets of the lipid bilayer of the cellular membrane in an energy‐independent manner. Recent studies have indicated that viral infection is closely related to cellular lipid distribution. The level and distribution of phosphatidylserine (PtdSer) in cells have been demonstrated to be critical regulators of viral infections. Previous studies have supported that the infection of human (...) immunodeficiency virus (HIV), Zika virus, Ebola virus (EBOV), influenza virus, and dengue fever virus require the externalization of phospholipids mediated by scramblases, which are also involved in the pathogenicity of the pandemic severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). In this review, we review the relationship of scramblases with viruses and the potential viral effector proteins that might utilize host scramblases. (shrink)

We argue that the most‐promising area of clinical application of microarrays in the foreseeable future is the diagnostics and monitoring of infectious diseases. Microarrays for the detection and characterization of human pathogens have already found their way into clinical practice in some countries.

Clinical application of microarray technologies for the detection (...) of mycobacteria, Bacillus anthracis, HIV, hepatitis and influenza viruses, and other major pathogens, as well as the analysis of their drug‐resistance patterns, illustrate our main thesis.

When labeling an infectious disease, officially sanctioned scientific names, e.g., “H1N1 virus,” are recommended over place-specific names, e.g., “Spanish flu.” This is due to concerns from policymakers and the WHO that the latter might lead to unintended stigmatization. However, with little empirical support for such negative consequences, authorities might be focusing on limited resources on an overstated issue. This paper empirically investigates the impact of naming against the current backdrop of the 2019–2020 pandemic. The first hypothesis posited that using (...) place-specific names associated with China leads to greater levels of sinophobia, the negative stigmatization of Chinese individuals. The second hypothesis posited that using a scientific name leads to increased anxiety, risk aversion, beliefs about contagiousness of the virus, and beliefs about mortality rate. Results from two preregistered studies [N = 504; N = 412], conducted across three countries with the first study during the early outbreak and the second study at a later stage of the pandemic, found no evidence of any adverse effects of naming on sinophobia and strong support for the null hypothesis using Bayesian analyses. Moreover, analyses found no impact of naming on anxiety, risk aversion, beliefs about contagiousness of the virus, or beliefs about mortality rate, with mild to strong support for the null hypothesis across outcomes. Exploratory analyses also found no evidence for the effect of naming being moderated by political affiliation. In conclusion, results provide no evidence that virus naming impacted individual’s attitudes toward Chinese individuals or perceptions of the virus, with the majority of analyses finding strong support for the null hypothesis. Therefore, based on the current evidence, it appears that the importance given to naming infectious diseases might be inflated. (shrink)

The coronavirus pandemic has stirred interest in viruses. This has been accompanied by a proliferation of popular works trying to explain how viruses fit into the Christian worldview. In an anthropocentric perspective, viruses are easily regarded as malicious entities. This article, however, shows that a proper understanding of the biology of viruses actually adds another level of complexity to our perception of good and evil. Interestingly, this additional layer of complexity might help us solve some of the most urgent difficulties (...) in the discussion about good and evil, if we recognize the subjective nature of what we call natural evil. We need to be more nuanced not merely in our theological discussion about good and evil, but also in the way we talk about viruses. (shrink)

This article aims to open up the biographical black box of three experts working in the boundary zone between science, policy and public debate. A biographical-narrative approach is used to analyse the roles played by the virologists Albert Osterhaus, Roel Coutinho and Jaap Goudsmit in policy and public debate. These figures were among the few leading virologists visibly active in the Netherlands during the revival of infectious diseases in the 1980s. Osterhaus and Coutinho in particular are still the key figures (...) today, as demonstrated during the outbreak of novel influenza A (H1N1). This article studies the various political and communicative challenges and dilemmas encountered by these three virologists, and discusses the way in which, strategically or not, they handled those challenges and dilemmas during the various stages of the field’s recent history. Important in this respect is their pursuit of a public role that is both effective and credible. We will conclude with a reflection on the H1N1 pandemic, and the historical and biographical ties between emerging governance arrangements and the experts involved in the development of such arrangements.

In 2016, following pandemic influenza threats and the 2014–2016 Ebola virus disease outbreaks, the WHO developed a guidance document for managing ethical issues in infectious disease outbreaks. In this article, we analyse some ethical issues that have had a predominant role in decision making in response to the current COVID-19 pandemic but were absent or not addressed in the same ways in the 2016 guidance document. A pandemic results in a health crisis and social and political crises both nationally (...) and globally. The ethical implications of these global effects should be properly identified so that appropriate actions can be taken globally and not just in national isolation. Our analysis, which is a starting point to test the broader relevance of the 2016 WHO document that remains the only available guidance document applicable globally, concludes that the WHO guidance should be updated to provide reasoned and thoughtful comprehensive ethics advice for the sound management of the current and future pandemics.

So-called ‘gain-of-function’ (GOF) research is virological research that results in a virus substantially more virulent or transmissible than its wild antecedent. GOF research has been subject to ethical analysis in the past, but the methods of GOF research have to date been underexamined by philosophers in these analyses. Here, we examine the typical animal used in influenza GOF experiments, the ferret, and show how despite its longstanding use, it does not easily satisfy the desirable criteria for ananimal model. We (...) then discuss the limitations of the ferret model, and how those epistemic limitations bear on ethical and policy questions around the risks and benefits of GOF research. We conclude with a reflection on how philosophy of science can contribute to ethical and policy debates around the risks, benefits and relative priority of life sciences research. (shrink)

In all cases, the protein contains a single transmembrane α-helix close to its N-terminus. Channels (...) can be formed by homo-oligomerization of these proteins, yielding bundles of transmembrane helices that span the membrane and surround a central ion-permeable pore. Molecular modeling may be used to integrate and interpret available experimental data concerning the structure of such transmembrane pores. This has proved successful for the M2 channel domain, where two independently derived models are in agreement with one another, and with solid-state nuclear magnetic resonance (NMR) data. Simulations based on channel models may yield insights into possible ion conduction and selectivity mechanisms. BioEssays 20:992–1000, 1998. © 1998 John Wiley & Sons, Inc. (shrink)

Due to the state of globalized clinical research, questions have been raised as to what, if any, benefits those who contribute to research should receive. One model for compensating research participants is “benefit sharing,” and the basic premise is that, as a matter of justice, those who contribute to scientific research should share in its benefits. While incorporated into several international documents for over two decades, benefit sharing has only been sparsely implemented. This analysis begins by addressing the concept of (...) benefit sharing, its historical development, and how it has been applied in the context of virus sharing for influenza research. The second portion of this analysis presents recommendations for ensuring benefit sharing. These recommendations are threefold: 1) an emphasis on social pressure, 2) the revision of international documents as means to ensure benefit sharing, and 3) greater collaboration between sponsor IRB and host country IRB. Because clinical research is a globalized industry, a global model will be proposed in the second that focuses on collaboration between the sponsor and host country. This collaboration is vital in order to ensure that proper forms of benefit sharing are accomplished as a matter of justice. (shrink)

In this article we investigate the way in which viral load assays are used to assess the viruses of Human Immunodeficiency Virus (HIV)-positive pregnant women who are cared for in an HIV-specialist antenatal clinic in London. One of the viral load assays has been made more sensitive to subtypes of the virus that are considered to be local, possibly reading the viruses of those who have ‘foreign’ subtypes as undetectable. Consequently, the patient might not be offered the kind of care (...) needed to prevent transmission of HIV, as her body is not recognised as sufficiently debilitated. Thus, being identified as a debilitated body in this setting facilitates the prevention of vertical transmission of HIV and the management of the HIV-positive pregnant patient's virus. Further to this, we argue that in our example, having a debilitated body as constructed by the viral load assay is thus a ‘privilege’ that is accorded to HIV-positive persons depending on the geographic origin of their virus. Using Karen Barad's agential realism, we argue that the manner in which HIV is read through the viral load assay constructs a specific woman/foetus/hiv phenomenon. The specificity of this phenomenon directly impacts on the course of care, opening up or foreclosing the possibility of her child having a future free from HIV. (shrink)

L’érosion actuelle de la confiance du public envers les campagnes de vaccination et les décisions de politiques publiques qui y sont associées, aggravée par des scandales comme ceux relatifs à la pandémie H1N1 et l’utilisation du Tamiflu™, risque de diminuer de façon significative l’efficacité de ces interventions importantes pour la santé publique. Un manque de confiance de la population envers les acteurs de santé publique peut conduire à une méfiance accrue face aux interventions, pouvant ainsi compromettre l’atteinte des objectifs (...) recherchés par une intervention spécifique et, conséquemment, avoir un impact important sur les bénéfices attendus pour la population visée par cette intervention. Dans la production des avis d’experts, les membres des comités consultatifs d’experts en immunisation (CCEI) peuvent avoir une influence importante sur la prise de décision publique, notamment, sur la sélection par les décideurs de santé publique de vaccins en particulier et la façon dont les campagnes de vaccination seront déployées. En contrepartie de cette influence sur les décisions publiques, une indépendance et une transparence sont attendues de leur part puisque des mécanismes de divulgation et de gestion de conflits d’intérêts (CI) imparfaits peuvent affecter négativement la confiance du public à l’égard de telles décisions. Il apparaît donc important de s’assurer que des mécanismes de gestion des CI, transparents et robustes, existent pour ces comités. Dans cette étude, les avis ou rapports d’évaluation de la pertinence de la vaccination préparés par un CCEI au Québec ont été examinés pour quatre types de maladies évitables par la vaccination (infections invasives à méningocoques et à pneumocoques, coqueluche et virus du papillome humain). Le but était de : 1) identifier les CI divulgués par les membres du CCEI dans leurs rapports comparativement à ceux déclarés dans leurs publications scientifiques pour ces mêmes infections ; 2) analyser la nature des CI (réel, potentiel, apparent, personnel, financier, institutionnel, etc.) et l’impact potentiel (risque) sur la prise de décision impartiale et sur la confiance du public ; et 3) évaluer les mécanismes de gestion de CI actuellement utilisés par ce CCEI. Les résultats de cette étude montrent que très peu de rapports du CCEI contiennent une section sur les CI par rapport à la pléthore divulguée dans les publications scientifiques publiées par les membres du CCEI. De plus, les CI divulgués dans les rapports fréquemment ne correspondent pas à ceux décrits dans les publications scientifiques. Il serait donc important d’introduire des mesures visant à accroître la transparence des experts en immunisation et d’améliorer les mécanismes de divulgation et de gestion des CI afin de veiller à ce que la confiance du public envers les décideurs en santé publique soit maintenue et améliorée.

Recent findings regarding the cellular biology and immunology of BST‐2 (also known as tetherin) indicate that its function could be exploited as a universal replication inhibitor of enveloped respiratory viruses (e.g., influenza, respiratory syncytial virus, etc.). BST‐2 inhibits viral replication by preventing virus budding from the plasma membrane and by inducing an antiviral state in cells adjacent to infection via unique inflammatory signaling mechanisms. This review presents the first comprehensive summary of what is currently known about BST‐2 anti‐viral function (...) against respiratory viruses, how these viruses construct countermeasures to antagonize BST‐2, and how BST‐2 function might be targeted to develop therapies to treat respiratory virus infections. The authors address the current gaps in knowledge, including the need for mechanistic understanding of BST‐2 antagonism by respiratory viruses, that should be bridged to achieve that goal. (shrink)

The Covid-19 pandemic has had a great impact on the life of every inhabitant of the planet. During 2020 and 2021 a significant amount of work on how the pandemic is being conceptualized and communicated has been done. Most work has focused on the role of metaphor in the construal of specific cognitive frames. In this paper, we turn to a similar but different conceptualization mechanism, i.e. simile. Drawing from recent socio-cognitive and discursive empirical approaches to similes, this paper focuses (...) on “target is like source” constructions in English and Spanish containing (corona)virus either as target or source of the simile. The analysis is based on 200 examples found in the digital media during the first wave of the pandemic in 2020. First, the constructions, conceptualizations and mappings are analyzed. Second, the relevant discourse features (genre type, relation to subjectivity, text location and structuring properties) are described. Finally, the cross-linguistic English-Spanish analysis shows that, despite the many coincidences in both datasets, there are different tendencies as for the use of culture-specific mappings and the genres where the similes occur in. The study aims at testing to what extent the general features characterizing similes also hold in the case of (corona)virus, both as source and as target. The corpus analysis contributes, in addition, to the emerging line of research on the use of figuration in the communication of the pandemic, as well as to the study of the discursive dimensions of similes in real settings.

The current Ebola virus epidemic in Western Africa appears to be spiraling out of control. The worst-case projections suggested that the unchecked spread could result in almost 1.4 million cases by the end of January 2015 with a case fatality rate of at least 50%. The United States and European nations have begun to respond in earnest with promises of supplies, isolation beds, and trained health care personnel in an effort to contain the epidemic and care for the sick. However, (...) there is neither a vaccine nor specific treatment for Ebola infection, and therapy is ideally centered on supportive care. I have previously argued that the provision of palliative care is obligatory during an overwhelming health catastrophe, notably pandemic influenza. Since affected Ebola patients have best outcomes with technologically advanced intensive care—resources in scarce supply in the area—I suggest that the only acceptable approach to large numbers of very sick, dying, and suffering Ebola patients who overwhelm the resources available to successfully manage them is effective palliative care. However, this could hasten death in this vulnerable population and hence, while ethically and medically justifiable, is not without social risk. (shrink)

One Health is a novel paradigm that recognizes that human and non-human animal health is interlinked through our shared environment. Increasingly prominent in public health responses to zoonoses, OH differs from traditional approaches to animal-borne infectious risks, because it also aims to promote the health of animals and ecological systems. Despite the widespread adoption of OH, culling remains a key component of institutional responses to the risks of zoonoses. Using the threats posed by highly pathogenic avian influenza viruses to (...) human and animal health, economic activity and food security as a case exemplar, we explore whether culling and other standard control measures for animal-borne infectious disease might be justified as part of OH approaches. Our central premise is that OH requires us to reformulate ‘health’ as universal good that is best shared across species boundaries such that human health and well-being are contingent upon identifying and meeting the relevant sets of human and non-human interests and shared dependencies. Our purpose is to further nascent discussions about the ethical dimensions of OH and begin to describe the principles around which a public health agenda that truly seeks to co-promote human and non-human health could potentially begin to be implemented.

It is argued that the major interpretations of tobacco mosaic virus which were suggested in the first half of the 20th century can be ordered into two conflicting approaches. It is shown that explaining the existence of these different approaches as views from different perspectives, is a mistaken metaphor. The different approaches resulted in the "construction" of different research objects as answers to the questions "What is a virus"? Although these different conceptions did exclude each other, they co-existed because of (...) the consensus concerning the existence of tobacco mosaic "disease". (shrink)
