Value of inventory information in allocating a limited supply of influenza vaccine during a pandemic.

To understand the value of information on vaccine inventory levels during an influenza pandemic, we propose a simulation study to compare vaccine allocation strategies using: (i) only population information (pro-rata, or population-based, PB), (ii) both population and vaccine inventory information (population and inventory-based, PIB).

Assessing the benefits of early pandemic influenza vaccine availability: a case study for Ontario, Canada.

New vaccine production technologies can significantly shorten the timelines for availability of a strain-specific vaccine in the event of an influenza pandemic. We sought to evaluate the potential benefits of early vaccination in reducing the clinical attack rate (CAR), taking into account the timing and speed of vaccination roll-out. Various scenarios corresponding to the transmissibility of a pandemic strain and vaccine prioritization strategies were simulated using an agent-based model of disease spread ...

Pandemic influenza vaccines: what they have taught us about B cell immunology.

The emergence of avian influenza viruses stimulated pandemic concerns and efforts to develop protective vaccines. Studies of the immune responses to experimental vaccines for pandemic influenza have taught us lessons about human immunity to influenza in general that can be applied to seasonal, pandemic, and even universal vaccine responses. For example, the concepts of targeting the hemagglutinin stalk and elicitation of stalk reactive antibodies grew out of studies of the 2009 pandemic H1N1 vaccines. More ...

The long-run effects of pandemic influenza on the development of children from elite backgrounds: Evidence from industrializing Japan.

This study estimates the lingering effects of fetal exposure to the 1918 influenza pandemic on the development of secondary school and girls' high school students in industrializing Japan. In order to refine the verification of the fetal origins hypothesis, we tried not only to focus on children from elite schools but also to construct the continuous influenza mortality measure using monthly variations in the number of births and influenza deaths. By utilizing a nationwide multidimensional physical examinat...

Incidence rates of narcolepsy diagnoses in Taiwan, Canada, and Europe: The use of statistical simulation to evaluate methods for the rapid assessment of potential safety issues on a population level in the SOMNIA study.

Vaccine safety signals require investigation, which may be done rapidly at the population level using ecological studies, before embarking on hypothesis-testing studies. Incidence rates were used to assess a signal of narcolepsy following AS03-adjuvanted monovalent pandemic H1N1 (pH1N1) influenza vaccination among children and adolescents in Sweden and Finland in 2010. We explored the utility of ecological data to assess incidence of narcolepsy following exposure to pandemic H1N1 virus or vaccination in 10 ...

Significance of the detection of Influenza and other respiratory viruses for Antibiotic Stewardship: The lessons from post-pandemic period.

Low coverage rate and awareness of influenza vaccine among older people in Shanghai, China: a cross-sectional study.

Older individuals are at high risk for morbidity and mortality due to influenza, and the most effective way to prevent influenza is yearly vaccination. In China, the influenza vaccine is not covered by the national Expanded Program on Immunization, and more evidence is needed about influenza vaccine usage among older individuals.

Generation of a High-Growth Influenza Vaccine Strain in MDCK Cells for Vaccine Preparedness.

As shown during the 2009 pandemic H1N1 [A(H1N1)pdm09] outbreak, egg-based influenza vaccine production technology is insufficient to meet global demand during an influenza pandemic. Therefore, there is a need to adapt cell culture-derived vaccine technology using suspended cell lines for more rapid and larger-scale vaccine production. In this study, we attempted to generate a high growth influenza vaccine strain in MDCK cells using an A/Puerto/8/1934 (H1N1) vaccine seed strain. Following 48 serial passages ...

Cell culture-derived flu vaccine: Present and future.

The benefit of influenza vaccines is difficult to estimate due to the complexity of accurately assessing the burden of influenza. To improve the efficacy of influenza vaccines, vaccine manufacturers have developed quadrivalent influenza vaccine (QIV) formulations for seasonal vaccination by including both influenza B lineages. Three parallel approaches for producing influenza vaccines are attracting the interest of many vaccine manufacturing companies. The first and oldest is the conventional egg-derived in...

Fortunately, many of these planning efforts can take place before a pandemic strikes to improve outcomes during a future...

Evaluation of the field-protective effectiveness of seasonal influenza vaccine among Korean children aged < 5 years during the 2014-2015 and 2015-2016 influenza seasons: a cohort study.

A field effectiveness evaluation of the influenza vaccine among children younger than five years is important due to the high burden of influenza in this age group. The epidemiology of influenza virus changes rapidly each year. Moreover, the development of a new type of influenza vaccine is accelerating, necessitating a new field effectiveness evaluation.

Mapping of the US Domestic Influenza Virologic Surveillance Landscape.

Influenza virologic surveillance is critical each season for tracking influenza circulation, following trends in antiviral drug resistance, detecting novel influenza infections in humans, and selecting viruses for use in annual seasonal vaccine production. We developed a framework and process map for characterizing the landscape of US influenza virologic surveillance into 5 tiers of influenza testing: outpatient settings (tier 1), inpatient settings and commercial laboratories (tier 2), state public health ...

A Live-Attenuated Prime, Inactivated Boost Vaccination Strategy with Chimeric Hemagglutinin-Based Universal Influenza Virus Vaccines Provides Protection in Ferrets: A Confirmatory Study.

Influenza viruses cause severe diseases and mortality in humans on an annual basis. The current influenza virus vaccines can confer protection when they are well-matched with the circulating strains. However, due to constant changes of the virus surface glycoproteins, the vaccine efficacy can drop substantially in some seasons. In addition, the current seasonal influenza virus vaccines do not protect from avian influenza viruses of human pandemic potential. Novel influenza virus vaccines that aim to elicit ...

The year 2018 marks 100 years since the 1918 influenza pandemic that caused devastating social and economic destruction worldwide. Despite substantial progress made with influenza research and strategies to control disease outbreaks, influenza continues to be a global public health problem. This paper presents a synopsis of the 4th New Zealand Influenza Symposium hosted by the Immunisation Advisory Centre in February 2018. During this symposium, international and national experts and service providers conve...

Improving influenza vaccines: challenges to effective implementation.

Influenza virus causes contagious respiratory illness and remains a major burden on healthcare systems and the economy. Seasonal influenza vaccine is the most cost-effective way to combat the disease. However, underestimation of disease severity and controversy over vaccine safety and effectiveness hampers public confidence in vaccination. Action is needed to restore public confidence and improve vaccine uptake. Tailoring seasonal influenza vaccines according to immune responsiveness and infection/vaccinati...

DNA vaccine priming for seasonal influenza vaccine in children and adolescents 6 to 17 years of age: A phase 1 randomized clinical trial.

Children are susceptible to severe influenza infections and facilitate community transmission. One potential strategy to improve vaccine immunogenicity in children against seasonal influenza involves a trivalent hemagglutinin DNA prime-trivalent inactivated influenza vaccine (IIV3) boost regimen.

Development and Regulation of Novel Influenza Virus Vaccines: A United States Young Scientist Perspective.

Vaccination against influenza is the most effective approach for reducing influenza morbidity and mortality. However, influenza vaccines are unique among all licensed vaccines as they are updated and administered annually to antigenically match the vaccine strains and currently circulating influenza strains. Vaccine efficacy of each selected influenza virus vaccine varies depending on the antigenic match between circulating strains and vaccine strains, as well as the age and health status of the vaccine rec...

Influenza vaccine failure: Failure to protect or failure to understand?

I propose that influenza vaccine failure be defined as receipt of a properly stored and administered vaccine with the subsequent development of documented influenza. Several mechanisms of vaccine failure occur and can-sometimes in combination-lead to what is termed "vaccine failure." Influenza vaccine failure occurs for a variety of reasons, many of which are not true failures of the vaccine (e.g., improper vaccine storage and handling). Areas covered: In this article, I discuss common causes of "vaccine fa...

Imprinting of Repeated Influenza A/H3 Exposures on Antibody Quantity and Antibody Quality: Implications on Seasonal Vaccine Strain Selection and Vaccine Performance.

Reduced seasonal influenza vaccine effectiveness (VE) was observed in individuals who received repeated annual vaccinations. Pre-existing influenza antibody levels were also found inversely correlated with post-vaccination titers. These reports suggest that pre-existing immunity may affect contemporary seasonal vaccine performance.

Pandemic influenza and subsequent risk of type 1 diabetes: a nationwide cohort study.

Case reports have linked influenza infections to the development of type 1 diabetes. We investigated whether pandemic and seasonal influenza infections were associated with subsequent increased risk of type 1 diabetes.

Universal influenza virus vaccines and therapeutics: where do we stand with influenza B virus?

The development of a broadly protective or universal influenza virus vaccine is currently a public health priority worldwide. The vast majority of these efforts is exclusively focused on influenza A viruses. While influenza A viruses cause the majority of all influenza cases worldwide, influenza B viruses should not be ignored. Approximately 25% of all influenza cases are caused by influenza B viruses which circulate as two distinct B/Victoria/2/87-like and B/Yamagata/16/88-like lineages. In contrast to pop...

Using Clinical Research Networks to Assess Severity of an Emerging Influenza Pandemic.

Early clinical severity assessments during the 2009 influenza A H1N1 pandemic (pH1N1) overestimated clinical severity due to selection bias and other factors. We retrospectively investigated how to use data from the International Network for Strategic Initiatives in Global HIV Trials, a global clinical influenza research network, to make more accurate case fatality ratio (CFR) estimates early in a future pandemic, an essential part of pandemic response.

Combination of M2e peptide with stalk HA epitopes of influenza A virus enhances protective properties of recombinant vaccine.

Influenza infection could be more effectively controlled if a multi-purpose vaccine with the ability to induce responses against most, or all, influenza A subtypes could be generated. Conserved viral proteins are a promising basis for the creation of a broadly protective vaccine. In the present study, the immunogenicity and protective properties of three recombinant proteins (vaccine candidates), comprising conserved viral proteins fused with bacterial flagellin, were compared.

Implementation of maternal influenza immunization in El Salvador: Experiences and lessons learned from a mixed-methods study.

The World Health Organization (WHO) recommends that countries prioritize pregnant women for influenza vaccination, yet few low- or middle-income countries (LMICs) have implemented maternal influenza immunization programs. To inform vaccine decision-making and operational planning in LMICs, there is a need to document and share experiences from countries that provide seasonal influenza vaccine to pregnant women, particularly those with high coverage, like El Salvador.

Intra-seasonal antibody repertoire analysis of a subject immunized with an MF59®-adjuvanted pandemic 2009 H1N1 vaccine.

During the height of the 2009 H1N1 swine-derived influenza pandemic, a clinical trial was conducted in which seven subjects were immunized using a monovalent, MF59®-adjuvanted vaccine, developed from an egg-passaged candidate vaccine virus (CVV), A/California/07/2009 X-181. Whole blood was collected prior to immunization and at 8, 22, and 202 days post-vaccination, and subjects' serological responses were evaluated. Here, we reconstruct and examine the longitudinal, influenza-specific circulating B cell ...
