Hungary's Health Minister says his country has developed a prototype vaccine to use against the deadly Asian strain of bird flu.
Jeno Racz says clinical trials of the vaccine have given positive results.
Hungarian authorities began testing the prototype on volunteers three weeks ago.
Meanwhile, the Swiss pharmaceutical firm Roche says its third-quarter sales rose 17 percent, sparked by a demand for drugs such as Tamiflu, an antiviral being stockpiled by governments as a defense against a possible flu pandemic.
More than 60 people in Asia have died from the H5N1 strain of the virus since 2003.
