Human H5N1 Vaccine Successfully Produced

Five batches of H5N1 vaccine including 5,000 doses for humans from chicken embryos have been successfully produced, announced a research team of the Nha Trang Institute of Vaccines and Biological Products.

The vaccine gave similar results after being tested on white mice, guinea-pig and cockerels. Five H5N1 vaccine batches were produced separately but their quality meet the requirements for immunity.

Nguyen Thi Minh Hien, a member of the team, said the institute will produce 5,000 more doses of the vaccine in early 2007 for tests at international verification centers. If it proves successful, the institute will propose to test on humans.

Furthermore, researchers of the Paster Institute in Ho Chi Minh City have decoded the gene sequence of 24 samples of flu type A-H5N1 which caused death to human being and poultry in the southern provinces in 2004-2005, said an official of the institute.

Scientists have found some mutations in all H5N1 lethal strains. From the above result, they will carry out researches on vaccines against flu human type A-H5N1 on human with vero cell – a safe cell.
