Annual seasonal influenza vaccine manufacturing cycles align with temperate country seasonality in each hemisphere, yet influenza seasonality is poorly defined for many countries. The study introduces a novel and universal approach to defining and classifying seasonality that can be used to classify any country's influenza vaccine cycle alignment.

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 b...
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...
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 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...
The 2017/18 winter influenza season in Hong Kong SAR started in early January 2018, predominated by influenza B/Yamagata. We collaborated with private medical practitioners of our sentinel surveillanc...
The World Health Organisation has warned that an influenza pandemic is inevitable. The avian influenza H5N1 virus strain is the leading candidate to cause the next influenza pandemic. This...
This is a study to assess the immune (antibody) response and safety of a bioCSL split virion, inactivated quadrivalent influenza vaccine, in comparison with a US licensed 2014/2015 trivale...
This phase 3 study is designed to obtain additional safety and immunogenicity data on Solvay's cell-derived seasonal trivalent subunit influenza vaccine in adult and elderly subjects witho...
The purpose of this study is to evaluate the body's immune response at different time points to an FDA-approved seasonal influenza vaccine. By better understanding the way the immune syste...
The aims of this study are: 1. to investigate if HIV infection alters the antibody responses to influenza and 2. to assess the ability of licensed influenza vaccine to induce functio...
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.
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.
Vaccines used to prevent infection by viruses in the family ORTHOMYXOVIRIDAE. It includes both killed or attenuated vaccines. The composition of the vaccines is changed each year in response to antigenic shifts and changes in prevalence of influenza virus strains. The vaccine is usually bivalent or trivalent, containing one or two INFLUENZAVIRUS A strains and one INFLUENZAVIRUS B strain.
A genus of the family ORTHOMYXOVIRIDAE comprising viruses similar to types A and B but less common, more stable, more homogeneous, and lacking the neuraminidase protein. They have not been associated with epidemics but may cause mild influenza. Influenza C virus is the type species.
Swine Flu - H1N1 influenza - H7N9
Swine flu is the common name given to a relatively new strain of influenza (flu) that caused a flu pandemic in 2009-2010. It is also referred to as H1N1 influenza (because it is the H1N1 strain of virus). The H1N1 flu virus will be one of the main vi...
Influenza or 'flu' is a respiratory illness associated with infection by influenza virus. Symptoms frequently include headache, fever, cough, sore throat, aching muscles and joints. There is a wide spectrum of severity of illness ranging from min...
