HA NOI – Viet Nam has successfully produced experimental version of bird flu vaccine to combat the virus which has killed 62 people in 9 years, researchers at Vaccine and Biological Production Company No.1, said.
Six series of vaccine to prevent the H5N1 virus were produced at the Vabiotech company's laboratory, which is run by the National Institute of Hygiene and Epidemiology (NIHE).
The first and second phases of testing the H5N1 vaccine, named Fluvax, on volunteers was reported successful. All volunteers who were injected with 7.5mcg or more of the vaccine have shown good immunity response. Volunteers only suffered minor side effects which disappeared within 24 hours.
Testing results proved the trial version has meet all criteria the WHO lists for developing the human vaccine, which Vabiotech researchers began studying in 2004.
Producing vaccines domestically will make Viet Nam more active in preventing the pandemic virus.
Statistics from NIHE show that between 2007 and 2010, 5-7 people contracted bird flu each year in Viet Nam. The cases were reported in provinces across the country, and most of those infected had contracted the virus after coming in contact with, or eating, poultry at the end of winter and beginning of spring. There is still no concrete proof the disease can be transmitted from human to human. – VNS
