Research on Influenza IgY or Respiratory system care

Anti-Influenza virus IgY

活動報告写真

Influenza, commonly known as "the flu", is one of the most important emerging and reemerging infectious diseases. It causes high morbidity and mortality in communities (epidemic) and worldwide (pandemic). Children under 1 year old, elderly people over 65 years, people with comorbid illness health problems, immuno-compromised patients, pregnant women, and certain ethnic groups are at highest risk. The type A viruses are the most virulent human pathogens among the three influenza types (A, B, C) and cause the most severe disease. Among different serotypes of type A influenza viruses, four serotypes H1N1, H2N2, H3N2 and H5N1 were responsible for influenza pandemics globally. Annual vaccination and anti-influenza drugs are the most important preventive and therapeutic measures, respectively, but their effects are limited due to the change of serotypes and poor applicability to a high-risk patients as well as the appearance of drug resistant strains.

Research report


IRIG recent research achievement

活動報告写真

Recent research works (see below quotations) have reported that IgY protects mice from infection with various influenza serotypes. These research works open the way for using IgY for prevention and treatment of influenza infections in human. IRIG staff are now working on applying IgY into various product forms including tablets, gums, spray, etc that may help reduce risks of catching influenza in human.
