Nationwide Study on the Course of Influenza A (H1N1) Infections in Hospitalized Children in the Netherlands During the Pandemic 2009-2010.

The influenza H1N1 pandemic of 2009-2010, provided a unique opportunity to assess the course of disease, as well as the analysis of risk factors for severe disease in hospitalized children (


Narcolepsy and 2009 H1N1 pandemic vaccination in Taiwan.

Several European countries have observed an association between narcolepsy and H1N1 vaccines containing AS03 adjuvant in children/adolescents. In Taiwan, a nationwide campaign starting November 2009 administered H1N1 vaccines without adjuvant or with MF59 adjuvant to 67% of children and 12% of adults.

Impact of H1N1 Influenza Vaccination on Child Morbidity in Guinea-Bissau.

In addition to vaccines' specific effects, vaccines may have non-specific effects (NSEs) altering the susceptibility to unrelated infections. Non-live vaccines have been associated with negative NSEs. In 2010, a campaign with the non-live H1N1-influenza vaccine targeted children 6-59 months in Guinea-Bissau.


Combined use of live-attenuated and inactivated influenza vaccines to enhance heterosubtypic protection.

The limited protection of current commerical vaccines necessitates the investigation of novel vaccine strategies for unpredictable outbreaks. To investigate the feasibility of using vaccines derived from Group 1 influenza A virus to induce broadly cross-reactive immune responses against multiple influenza subtypes, we tested a panel of sequential 4-dose immunization regimens in mice. Mice were treated with inactivated (seasonal H1N1, pandemic H1N1 and H5N1) and vaccinia virus-based H5N1 live-attenuated vacc...

Evaluation of correlates of protection against influenza A(H3N2) and A(H1N1)pdm09 infection: Applications to the hospitalized patient population.

Influenza vaccines are important for prevention of influenza-associated hospitalization. However, the effectiveness of influenza vaccines can vary by year and influenza type and subtype and mechanisms underlying this variation are incompletely understood. Assessments of serologic correlates of protection can support interpretation of influenza vaccine effectiveness in hospitalized populations.

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 ...

Clinical evaluation of rapid fluorescent diagnostic immunochromatographic test for influenza A virus (H1N1).

Rapid diagnostic tests (RDTs) have been developed to detect influenza A virus for the swift diagnosis and management of patients. However, despite the simplicity and convenience, the low sensitivity of RDTs remains a limitation for their use in point of care testing (POCT). In this study, we developed a rapid fluorescent immunochromatographic strip test (FICT) and the performance of FICT was confirmed by the real-time reverse transcription-polymerase chain reaction (rRT-PCR) of H1N1, compared with that of R...

Evidence of pandemic H1N1 influenza exposure in dogs and cats, Thailand: A serological survey.

Influenza A virus causes respiratory disease in both humans and animals. In this study, a survey of influenza A antibodies in domestic dogs and cats was conducted in 47 animal shelters in 19 provinces of Thailand from September 2011 to September 2014. One thousand and eleven serum samples were collected from 932 dogs and 79 cats. Serum samples were tested for influenza A antibodies using a multi-species competitive NP-ELISA and haemagglutination inhibition (HI) assay. The NP-ELISA results showed that 0.97% ...

Safety and immunogenicity of influenza A(H5N1) vaccine stored up to twelve years in the National Pre-Pandemic Influenza Vaccine Stockpile (NPIVS).

As part of the U.S. Department of Health and Human Services (HHS) Pandemic Influenza Plan preparedness and response strategy, the National Pre-Pandemic Influenza Vaccine Stockpile (NPIVS) program was established by the Biomedical Advanced Research and Development Authority (BARDA) in 2005 with the goal of building and maintaining a stockpile of vaccines for influenza viruses with pandemic potential to vaccinate 20 million people in the critical workforce in the event of a pandemic. The NPIVS program continu...

Excess influenza hospital admissions and costs due to the 2009 H1N1 pandemic in England.

Influenza pandemics considerably burden affected health systems due to surges in inpatient admissions and associated costs. Previous studies underestimate or overestimate 2009/2010 influenza A/H1N1 pandemic hospital admissions and costs. We robustly estimate overall and age-specific weekly H1N1 admissions and costs between June 2009 and March 2011 across 170 English hospitals. We calculate H1N1 admissions and costs as the difference between our administrative data of all influenza-like-illness patients (sea...

A neuraminidase activity-based microneutralization assay for evaluating antibody responses to influenza H5 and H7 vaccines.

Outbreaks of the highly pathogenic avian influenza H5N1 and H7N9 viruses have spurred an unprecedented research effort to develop antivirals and vaccines against influenza. Standardized methods for vaccine evaluation are critical for facilitating vaccine development. Compared with hemagglutination inhibition assays, mounting evidence suggest that microneutralization tests (MNTs) is a better choice for the evaluation of candidate pandemic influenza vaccines because they measure neutralizing antibody activity...

Taiwan's Annual Seasonal Influenza Mass Vaccination Program-Lessons for Pandemic Planning.

Rapid medical countermeasure (MCM) dispensing is an important intervention during a public health emergency. In the United States, MCM planning and exercising efforts have largely focused on dispensing therapeutics, with less emphasis on mass vaccination operations that would require additional specialized staff and infrastructure. Difficulties in distributing vaccines during the 2009 H1N1 influenza pandemic highlighted the need for enhanced planning and exercising of plans for conducting mass vaccination c...

Timely Antiviral Administration During an Influenza Pandemic: Key Components.

Prompt treatment of ill persons with influenza antivirals will be an important part of a future pandemic influenza response. This essay reviews key lessons learned from the 2009 H1N1 pandemic and the changing landscape of antiviral drug availability, and identifies and describes the multiple components needed to ensure the timely administration of antiviral drugs during a future pandemic. 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.

Historical and clinical aspects of the 1918 H1N1 pandemic in the United States.

One hundred years have passed since the 1918 influenza pandemic caused substantial illness globally, with an estimated 50 million deaths. A number of factors, including World War I, contributed to the spread of the pandemic virus, which often caused high symptomatic attack rates and severe illness. Major achievements over the last 100 years have been made in influenza prevention, diagnosis, and treatment; however, the potential for a severe pandemic to emerge remains unchanged. We provide a review of the hi...

Structure and applications of novel influenza HA tri-stalk protein for evaluation of HA stem-specific immunity.

Long alpha helix (LAH) from influenza virus hemagglutinin (HA) stem or stalk domain is one of the most conserved influenza virus antigens. Expression of N-terminally extended LAH in E. coli leads to assembly of α-h elical homotrimer which is structurally nearly identical to the corresponding region of post-fusion form of native HA. This novel tri-stalk protein was able to differentiate between group 1 and 2 influenza in ELISA with virus-infected mice sera. It was also successfully applied for enzyme-linked...

Investigating the Legacy of 1918 Pandemic on Age-Related Sero-Epidemiology and Immune Responses to Subsequent Influenza A(H1N1) Viruses Through a Structural Equation Model.

Influenza A(H1N1) strains were responsible for two pandemics in the last century. As infections early in life may have long-lasting influence on future immune response against other influenza strains, we drew on previously collected sero-incidence data (n = 2554) to investigate if the 1918 pandemic virus and its early descendants produced an age-related signature in immune responses against the A/California/7/2009(H1N1)pdm09 virus of 2009. Hemagglutination inhibition assays revealed a J-shaped relationshi...

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...

Human-Origin Influenza A(H3N2) Reassortant Viruses in Swine, Southeast Mexico.

The genetic diversity of influenza A viruses circulating in swine in Mexico complicates control efforts in animals and presents a threat to humans, as shown by influenza A(H1N1)pdm09 virus. To describe evolution of swine influenza A viruses in Mexico and evaluate strains for vaccine development, we sequenced the genomes of 59 viruses and performed antigenic cartography on strains from 5 regions. We found that genetic and antigenic diversity were particularly high in southeast Mexico because of repeated intr...

Broadly protective influenza vaccines: design and production platforms.

Effective vaccines are the cornerstone of our defenses against acute influenza virus infections that result in ∼500 000 annual deaths worldwide. For decades, an on-going concerted effort has been to develop a universal influenza vaccine to combat the looming threat of potentially pandemic emerging and re-emerging influenza viruses. To address the need for rapid efficacious vaccines that could mitigate the impact of seasonal and future pandemics, multiple platforms are under development and/or investigat...

Influenza-Mediated Lung Infection Models.

Laboratory rodent influenza infection models have been and continue to be a critical tool for understanding virus-host interactions during infection. The incidence of seasonal influenza infections coupled with the need for novel therapeutics and universal vaccines highlights the need to uncover novel mechanisms of pathogenesis and protection. Mouse models are extremely useful for the evaluation of influenza vaccines and provide an invaluable tool to probe the immune response. This chapter describes the tech...

The evolutionary dynamics of H1N1/pdm2009 in India.

After the 2009 pandemic H1N1 outbreak, this new reassortant virus replaced the previous seasonal H1N1 and established itself in human populations. In 2014-2015, the H1N1/pdm2009 pandemic strain caused the worst influenza outbreak in India in recent years. It is still unclear whether this outbreak was due to a genetic change in the H1N1/pdm2009 virus. Here, we collected all available data from India, and used data from other South and Southeast Asian countries (Bangladesh, Myanmar, Nepal, Singapore, and Viet...

Influenza vaccination coverage among US-Mexico land border crossers: 2009 H1N1 pandemic and 2011-2012 influenza season.

The high volume of US-Mexico land border crossings can facilitate international dissemination of influenza viruses.

Structure-aided drug development of potential neuraminidase inhibitors against pandemic H1N1 exploring alternate binding mechanism.

The rate of mutability of pathogenic H1N1 influenza virus is a threat. The emergence of drug resistance to the current competitive inhibitors of neuraminidase, such as oseltamivir and zanamivir, attributes to a need for an alternative approach. The design and synthesis of new analogues with alternate approach are particularly important to identify the potential neuraminidase inhibitors which may not only have better anti-influenza activity but also can withstand challenge of resistance. Five series of scaff...

The origins of the great pandemic.

The timing and location of the first cases of the 1918 influenza pandemic are still controversial, a century after the pandemic became widely recognized. Here, we critically review competing hypotheses on the timing and geographical origin of this important outbreak and provide new historical insights into debates within military circles as to the nature of putative pre-1918 influenza activity. We also synthesize current knowledge about why the 1918 pandemic was so intense in young adults. Although it is st...
