In January 2007, Tianyuan's Flu Vaccine "YUGANNING" was for the first time exported to South-America after previous exports to Asian and European markets. Registrations in other countries are in progress, as Tianyuan wants to increase its' export business and to explore new opportunities.
Influenza is an infection of the respiratory tract caused by influenza virus. It involves a combination of respiratory (cough, sore throat) and constitutional (fever, headache, muscle aches) symptoms. In Children, older adults and people with a range of pre-existing medical conditions influenza infections can lead to serious and even life threatening complications.
As the circulating viruses change by mutation infections can occur repeatedly throughout life and protection by vaccination requires annual dosing with updated vaccines. Seasonal vaccination prevents influenza and reduces the impact of epidemics.
Tianyuan's influenza vaccine YUGANNING is an inactivated split vaccine, produced on embryonated chicken eggs. The vaccine is manufactured according to the seasonal WHO recommendation for Northern and Southern Hemisphere. The vaccine's quality level is comparable to internationally available vaccines. Tianyuan aspires to get the WHO pre-qualification status for YUGANNING.
