A SARS (severe acute respiratory syndrome) vaccine has been
developed and is entering a preliminary clinical testing period,
the Ministry of
Science and Technology has confirmed. Some 30 people have
already volunteered to be the first test subjects.??
After nine months continual effort, the vaccine passed a State
Food and Drug Administration evaluation, said Li Xueyong, vice
minister of science and technology and also deputy director of the
national SARS vaccine technical group.
The first phase test aimed to see if it was safe and effective
on the human body.
The clinical study will involve production of a SARS vaccine by
killing the virus with heat, the official said.
Scientists hope that testing the vaccine on volunteers will not
cause SARS, but instead work to make the human body immune to the
disease.
The move is a milestone in the country's anti-SARS efforts,
Zheng Youyu, director of the State Food and Drug Administration,
said, but it would still take time to make the vaccine
marketable.
The vaccine was found safe in experiments on animals, including
the rhesus monkey, said Zheng. Since last year's outbreak of SARS,
Chinese scientists had worked strenuously to find an anti-SARS
vaccine, said Li. The ministry had mobilized all resources to
support the research.
On Monday the latest Guangdong SARS patient, a 35-year-old
private businessman, was still hospitalized but had a normal
temperature for 13 consecutive days.
"None of the people in contact with him has developed a fever or
shown other abnormal symptoms,'' he said.
No new SARS cases were reported in the 24 hours from 10 am
Sunday to 10 am yesterday on the Chinese mainland, according to the
ministry's daily SARS report.
So far, China has reported three diagnosed SARS cases this year,
all from Guangdong.
The other two cases, a 32-year-old TV producer and a 20-year-old
waitress, have been discharged from hospital earlier this
month.
All three cases appeared to be milder than those in the SARS
outbreak last year. Experts with the World Health Organization said
the three patients all recovered quickly and had low infection
levels.
Across the nation, stricter disease prevention measures are
being made during the holidays of Chinese traditional Lunar New
Year or Spring Festival, Ministry of Health officials said
Monday.
A smooth and efficient epidemic reporting system will continue
to be maintained along with the daily SARS monitoring report during
the festival season, a spokesman said.
