A locally developed emergency vaccine against the virulent H5N1 strain of bird flu is expected to be ready for clinical trials in the second half of this year, a senior Department of Health (DOH) official said on Friday.
The emergency vaccine, developed by the National Health Research Institute, will mainly be used for emergency use in the event of an H5N1 outbreak in humans, said Shih Wen-yi (施文儀), deputy director of the DOH’s Centers for Disease Control.
Shih said the DOH was scheduled to authorize clinical trials for the locally developed bird flu vaccines in the second quarter of this year and that the first phase of the trials were expected to get underway in the third quarter.
As the research institute has a limited production capacity, Shih said, the locally developed vaccine would only be enough for emergency use if Taiwan was struck by an H5N1 outbreak in humans.
A few years ago, the DOH launched a build-operate-own (BOO) project under which a private contractor was chosen to produce locally developed human bird flu vaccines.
The bid, however, was dropped because the winning contractor was later merged into another entity in a corporate restructuring.
Shih said the DOH was appraising the feasibility of renewing the BOO project to draw the private sector into investing in human H5N1 vaccine production.
Meanwhile, a research team headed by Academia Sinica President Wong Chi-huey (翁啟惠) at the institute’s Genomics Research Center has developed DNA-based vaccines against both human influenza and avian flu, academic sources said.
The sources said the procedural platform developed by the team could produce the DNA-based vaccines for emergency use within six months.
The team’s research findings have been published in the US science journal Proceedings of the National Academy of Sciences of the United States of America.
A tropical depression east of the Philippines became a tropical storm early yesterday, the Central Weather Administration (CWA) said, less than a week after a typhoon barreled across the nation. The agency issued an advisory at 3:30am stating that the 22nd tropical storm, named Yinxing, of the Pacific typhoon season formed at 2am. As of 8am, the storm was 1,730km southeast of Oluanpi (鵝鑾鼻), Taiwan’s southernmost point, with a 100km radius. It was moving west-northwest at 32kph, with maximum sustained winds of 83kph and gusts of up to 108kph. Based on its current path, the storm is not expected to hit Taiwan, CWA
Residents have called on the Taipei City Government to reconsider its plan to demolish a four-decades-old pedestrian overpass near Daan Forest Park. The 42-year-old concrete and steel structure that serves as an elevated walkway over the intersection of Heping and Xinsheng roads is to be closed on Tuesday in preparation for demolition slated for completion by the end of the month. However, in recent days some local residents have been protesting the planned destruction of the intersection overpass that is rendered more poetically as “sky bridge” in Chinese. “This bridge carries the community’s collective memory,” said a man surnamed Chuang

NEW DESTINATIONS: Marketing campaigns to attract foreign travelers have to change from the usual promotions about Alishan and Taroko Gorge, the transport minister said The number of international tourists visiting Taiwan is estimated to top 8 million by the end of this year, Minister of Transportation and Communications Chen Shi-kai (陳世凱) said yesterday, adding that the ministry has not changed its goal of attracting 10 million foreign travelers this year. Chen made the remarks at a meeting of the legislature’s Transportation Committee to brief lawmakers about the ministry’s plan to boost foreign visitor arrivals. Last month, Chen told the committee that the nation might attract only 7.5 million tourists from overseas this year and that when the ministry sets next year’s goal, it would not include
