This is a randomized, un-blinded, Phase II study in males and non-pregnant females, who are in good health, 19 to 64 years of age. This study is designed to assess the safety, reactogenici...
This is a single center, randomized, partially-blinded, Phase II, small, targeted, prospective study in approximately 30 healthy male and non-pregnant female subjects aged 18 to 49 years o...
This is a trial designed to assess the safety, reactogenicity and immunogenicity of one or two doses of monovalent inactivated split influenza 2013 and 2017 A/H7N9 virus vaccines administe...
The study will be an open-label phase 2 clinical trial of a single dose of an inactivated H7N9 vaccine (non-adjuvanted). The subjects of the study will be individuals who previously partic...
This Phase II randomized, double-blinded, controlled study in up to 1000 males and non-pregnant females, 19 to 64 years old, inclusive, who are in good health and meet all eligibility crit...
Since the first case of human avian influenza A (H7N9) virus infection in 2013, five H7N9 epidemics have occurred in China, all of which caused severe diseases, including pneumonia and acute respirato...
The low pathogenic avian influenza A(H7N9) viruses (LPAI) were first identified in 2013 and have continued to infect humans since then. It was reported in February 2017 that the LPAI H7N9 virus has ev...
The aim of this study was to compare the clinical features of patients with avian influenza A (H7N9) and influenza A (H1N1) complicated by acute respiratory distress syndrome (ARDS).The clinical data ...
Since the first case of novel H7N9 infection was reported, China has experienced five epidemics of H7N9. During the fifth wave, a highly pathogenic H7N9 strain emerged. In order to assess whether the ...
Avian influenza A virus (AIV) H7N9 has caused five epidemic waves of human infections in China since 2013. AIVs may face strong selection to adapt to novel conditions when establishing themselves in h...
A subtype of INFLUENZA A VIRUS with the surface proteins hemagglutinin 7 and neuraminidase 9. This avian origin virus was first identified in humans in 2013.
Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
A subtype of INFLUENZA A VIRUS that is highly virulent in poultry and wild birds, but shows varying degrees of pathogenicity in mice. The H5N8 virus subtype has a polybasic amino acid motif at the HA cleavage site which explains its pathogenicity in birds, and expresses surface proteins HEMAGGLUTININ 5 and NEURAMINIDASE 8 which are typical of Highly Pathogenic Avian Influenza viruses.
