To develop a universal influenza vaccine, NIAID will focus resources on three key areas of influenza research: The authors state that a coordinated effort of guided discovery, facilitated product development and managed progress through iterative clinical testing will be critical to achieving the goal of a universal influenza vaccine.
For the new study, the Canadian researchers analyzed the medical records of nearly 10, children, aged Flu infection study increases understanding of natural immunity January 23, People with higher levels of antibodies against the stem portion of the influenza virus hemagglutinin HA protein have less viral shedding when they get the flu, but do not have fewer or less severe signs of illness, according Breadth or coverage of vaccine protection against influenza viruses, ranging from the least breadth ie, strain-specific protection through pan-group protection [ 11 ] to the greatest breadth ie, universal protection [ 12 ].
Research addressing this objective will aim to Develop the capability to rapidly characterize circulating influenza viruses from humans and animal reservoirs to assess the breadth of protection required from vaccines.
However, "nudging" clinical staff NIAID unveils strategic plan for developing a universal influenza vaccine WHAT Developing a universal influenza vaccine — a vaccine that can provide durable protection for all age groups against multiple influenza strains, including those that might cause a pandemic — is a priority for the National Institute of Allergy and Infectious Diseases NIAIDpart of the National Institutes of Health.
Breadth or coverage of vaccine protection against influenza viruses, ranging from the least breadth ie, strain-specific protection through pan-group protection [ 11 ] to the greatest breadth ie, universal protection [ 12 ].
Today, there is a well-established domestic vaccine manufacturing capacity, stockpiles of influenza vaccines and therapeutics, and evidence-based guidance on prevention, mitigation and treatment available for state and local governments, the private sector, individuals, and families.
Figure 1 illustrates the steps that can guide ongoing research in this area.
All women should get the annual flu vaccine, the U. Advances in influenza virology, immunology and vaccinology make the development of a universal influenza vaccine more feasible than a decade ago, according to the authors.
Determine the role of antineuraminidase NA antibodies in preventing virus budding, release, and transmission. Similarly, the emergence of a novel influenza virus with pandemic potential requires the development of a strain-specific vaccine to protect humans for an epidemic that might never occur.
The authors emphasize that broad collaboration and coordination in many disciplines and involving government, academia, philanthropies and the private sector will be vital to achieving the goal of developing a universal influenza vaccine. Comprehensive profiling of human immune responses, coupled with high-throughput viral sequencing and bioinformatics, can determine the critical immune components required for induction of long-term, broadly protective immunity against influenza.
If you do develop the flu while pregnant, the CDC suggests: However, this approach has limitations and difficulties. Four such pandemics have occurred in the past century, during,and [ 4 ]. An understanding of how to reduce severe influenza with seasonal or pandemic strains may guide novel strategies for the development of improved vaccines.
Criteria for a universal influenza vaccine. The lowest effectiveness occurs when vaccine strains are not well matched to circulating strains.
Accurately predicting how circulating influenza viruses will evolve is critical to improving vaccine efficacy. Define the mechanisms of broadly protective humoral immunity against influenza, including processes that affect immunodominance, based on antigen specificity, avidity, accessibility, or precursor frequency.
Strategic plan for developing a universal influenza vaccine February 28,NIH/National Institute of Allergy and Infectious Diseases A universal influenza vaccine should be at least 75% effective, protect against influenza A groups 1 and 2, protect for at least 1 year, and be suitable for all ages.
Researchers at the National Institute of Allergy and Infectious Diseases have orchestrated a plan to create a universal influenza vaccine. NIAID reveals strategic plan for universal influenza vaccine. March 1, Vaccinating against seasonal flu.
The strategic plan builds upon a workshop NIAID convened in June that gathered scientists from academia, industry and government who developed criteria for defining a universal influenza. The National Strategic Plan for Prevention, Control, Preparedness and Response to Avian Influenza, Influenza Pandemic, and Emerg Completed Initiation of.
The strategic plan builds upon a workshop NIAID convened in June that gathered scientists from academia, industry and government who developed criteria for defining a universal influenza vaccine, identified knowledge gaps, and delineated research strategies for addressing those gaps.
