SHANGHAI: As the threat of bird flu grows around the world, a leading
institute affiliated to the Chinese Academy of Sciences declared that it would
produce Tamiflu, the only drug said to be effective against the virus.
"If the epidemic spreads, we will produce our own version of Tamiflu," Wu
Jiarui, vice-president of the Shanghai Institute of Biological Sciences, said
Swiss-based Roche Holding AG holds the sole patent for Tamiflu but under
Chinese law, it could be sidestepped in case of a public health crisis.
Scientists agree it is easy to produce Tamiflu once the proper materials are
available although the process is complicated. The institute has got the right
materials, said Wu.
The primary goal is to try to produce a Chinese version of shikimic acid, the
active ingredient in Tamiflu, which is derived from star anise a spice widely
produced and used in China but Wu said the acid is also found in other plants
used in traditional Chinese medicine herbs.
Meanwhile, Shanghai Pharmaceutical Group Co Ltd (SPG) expects a "very
positive response" from Roche on its application to produce Tamiflu, which it
submitted last week.
Huang Yanzheng, vice-president of SPG and board chairman of Shanghai Roche a
joint venture between Roche and SPG said it would take about six months for SPG
to mass-produce Tamiflu once Roche gives the go-ahead.
As public anxiety about bird flu grows in the country, all segments of the
poultry industry have been hit hard.
Prices for chicks have plummeted 90 per cent in some areas, from 2 yuan (US
25 cents) to 0.2 yuan (US 2.5 cents), the Information Centre of China Feed
Supermarkets have cut down purchases of dressed chickens and ducks because of
Wumart, a Beijing-based chain supermarket, said it had cut purchases by half
in the past two weeks.
Shandong Liuhe Group, one of the country's leading suppliers of live fowl and
poultry feed, said it suffered a loss of 4 million yuan (US$494,000) last month
The group's vice-chairman, surnamed Zhang, said the company has been forced
to adopt a "zero profit" strategy this month in the live-fowl business. Sales of
poultry feed dropped by 10 per cent last month and may see a 20-30 per cent drop
in the next few months, he added.
The price of soybeans, an ingredient in bird feed, saw a decline, too.
Soybean prices at the Dalian Commodity Exchange dropped 2 per cent yesterday,
Bloomberg reported, adding that the sluggish business has exerted its influence
on American market.
It said soybeans in Chicago had the biggest two-session drop in two months on
speculation that demand from China, the biggest importer of the oilseed, will
drop as the country culls millions of birds.
Soybeans for January delivery dropped 9 cents, or 1.5 per cent, to US$5.83 a
bushel on the Chicago Board of Trade, bringing the two-session decline to 3.1
per cent, the most since August 25.
Meanwhile, the Ministry of Agriculture yesterday told farmers to buy poultry
vaccines only from nine designated drug makers after a counterfeit bird flu
vaccine was found in Northeast China.
The ministry revealed that a bogus bird flu vaccine produced by a biotech
pharmaceutical company in North China's Inner Mongolia Autonomous Region had
been sold in Liaoning Province, where the latest bird flu outbreak occurred.
"The harm (of fake vaccines) is incalculable," said Jia Youling, director of
the Veterinary Bureau of the Ministry of Agriculture.
If they contain active viruses, they could spread and possibly harm both
poultry and humans, he warned.
