Abstract

This commentary argues that 100 years after the deadly Spanish flu, the public health emergency community’s responses to much more limited pandemics and outbreaks demonstrate a critical shortage of personnel and resources. Rather than relying on nonpharmaceutical interventions, such as quarantine, the United States must reorder its health priorities to ensure adequate preparation for a large-scale pandemic.

Abstract

Physicians assume a primary ethical duty to place the welfare of their patients above their own interests. Thus, for example, physicians must not exploit the patient-physician relationship for personal financial gain through the practice of self-referral. But how far does the duty to patient welfare extend? Must physicians assume a serious risk to their own health to ensure that patients receive needed care? In the past, physicians were expected to provide care during pandemics without regard to the risk to their own health. In recent decades, however, the duty to treat during pandemics has suffered from erosion even while the risks to physicians from meeting the duty has gone down. After exploring the historical evolution of the duty to treat and the reasons for the duty, I conclude that restoring a strong duty to treat would protect patient welfare without subjecting physicians to undue health risks.

Abstract

A century ago, nonpharmaceutical interventions such as school closings, restrictions on large gatherings, and isolation and quarantine were the centerpiece of the response to the Spanish Flu. Yet, even though its cause was unknown and the science of vaccine development was in its infancy, considerable enthusiasm also existed for using vaccines to prevent its spread. This desire far exceeded the scientific knowledge and technological capabilities of the time. Beginning in the early 1930s, however, advances in virology and influenza vaccine development reshaped the relative priority given to biomedical approaches in epidemic response over traditional public health activities. Today, the large-scale implementation of nonpharmaceutical interventions akin to the response to the Spanish Flu would face enormous legal, ethical, and political challenges, but the enthusiasm for vaccines and other biomedical interventions that was emerging in 1918 has flourished. The Spanish Flu functioned as an inflection point in the history of epidemic responses, a critical moment in the long transition from approaches dominated by traditional public health activities to those in which biomedical interventions are viewed as the most potent and promising tools in the epidemic response arsenal.

Abstract

Objectives.

To show how the Centers for Disease Control and Prevention’s Pandemic Vaccine Campaign Planning Tool (PanVax Tool) can help state and local public health emergency planners demonstrate and quantify how partnerships with community vaccine providers can improve their overall pandemic vaccination program readiness.

Methods.

The PanVax Tool helps planners compare different strategies to vaccinate their jurisdiction’s population in a severe pandemic by allowing users to customize the underlying model inputs in real time, including their jurisdiction’s size, community vaccine provider types, and how they allocate vaccine to these providers. In this report, we used a case study with hypothetical data to illustrate how jurisdictions can utilize the PanVax Tool for preparedness planning.

Results.

By using the tool, planners are able to understand the impact of engaging with different vaccine providers in a vaccination campaign.

Conclusions.

The PanVax Tool is a useful tool to help demonstrate the impact of community vaccine provider partnerships on pandemic vaccination readiness and identify areas for improved partnerships for pandemic response.

Abstract

In the twenty-first century, severe acute respiratory syndrome (SARS), 2009 A(H1N1) influenza, and Ebola have all placed strains on critical care systems. In addition to the increased patient needs common to many disasters, epidemics may further degrade ICU capability when staff members fall ill, including in the course of direct patient care. In a large-scale pandemic, shortages of equipment and medications can further limit an ICU’s ability to provide the normal standard of care. Hospital preparedness for epidemics must include strategies to maintain staff safety, secure adequate supplies, and have plans for triage and prioritization of care when necessary.

Pandemic bonds: designed to fail in Ebola

Olga Jonas

___

The final toll of the Ebola outbreak in West Africa in 2014–16 was more than 11,000 lives, plus an estimated US$53 billion from economic disruption and collapse of health systems. In the outbreak’s wake, the global health community scrambled to deliver initiatives for increased health security. One flagship programme was the World Bank’s Pandemic Emergency Financing Facility (PEF). Under the scheme, investors who buy pandemic bonds receive generous ‘coupons’, which annually pay about 13% interest. This compensates investors for the risk that the bonds will make ‘insurance’ payouts to fight pandemics under certain conditions. Otherwise, cash returns to the investors when the bonds mature in July 2020.

Abstract

Since 1997, the highly pathogenic influenza H5N1 virus has spread from Hong Kong. According to the WHO bulletin report, the H5N1 virus is a zoonotic disease threat that has infected more than 850 humans, causing over 450 deaths. In addition, an outbreak of another new and highly pathogenic influenza virus (H7N9) occurred in 2013 in China. These highly pathogenic influenza viruses could potentially cause a worldwide pandemic. it is crucial to develop a rapid production platform to meet this surge demand against any possible influenza pandemic. A potential solution for this problem is the use of cell-based bioreactors for rapid vaccine production. These novel bioreactors, used for cell-based vaccine production, possess various advantages. For example, they enable a short production time, allow for the handling highly pathogenic influenza in closed environments, and can be easily scaled up. In this study, two novel disposable cell-based bioreactors, BelloCell and TideCell, were used to produce H5N1 clade II and H7N9 candidate vaccine viruses (CVVs). Madin-Darby canine kidney (MDCK) cells were used for the production of these influenza CVVs. A novel bench-scale bioreactor named BelloCell bioreactor was used in the study. All culturing conditions were tested and scaled to 10 L industrial-scale bioreactor known as TideCell002. The performances of between BelloCell and TideCell were similar in cell growth, the average MDCK cell doubling time was slightly decreased to 25 hours. The systems yielded approximately 39.2 and 18.0 μg/ml of HA protein with the 10-liter TideCell002 from the H5N1 clade II and H7N9 CVVs, respectively. The results of this study not only highlight the overall effectiveness of these bioreactors but also illustrate the potential of maintaining the same outcome when scaled up to industrial production, which has many implications for faster vaccine production. Although additional studies are required for process optimization, the results of this study are promising and show that oscillating bioreactors may be a suitable platform for pandemic influenza virus production.
