Vietnam begins second human trial of bird flu vaccine
The Ministry of Health Saturday started the first stage of a second human trial for a human vaccine for the H5N1 virus.
An official from the ministry said 30 volunteers from the Military Medical Academy in Ha Tay Province near Hanoi were injected with a one millimeter dose of the vaccine.
Stage One of the trial is expected to last for 56 days.
After the first injection, the volunteers’ health will be closely monitored and they will undergo blood tests.
