BEIJING (AP) - A Chinese-developed vaccine against the H5N1 strain of bird flu in humans has been found safe in the first round of tests, a government news agency reported Monday.
Researchers began work on the vaccine last year, and the government said it was ready to start mass production. But any vaccine would face more tests before it could be approved for human use.
Tests were conducted on six human volunteers at a Beijing hospital between November and June, the official Xinhua News Agency said.
