China is expected to conduct clinical experiments of a vaccine
for severe acute respiratory syndrome (SARS)
by the end of December, leading the world in the search for the
world's first vaccine against the deadly disease, a drug official
said Saturday.
Yin Hongzhang, head of the Biological Product Section of the
State Food and Drug Administration, said the administration is
expected to approve clinical tests of the vaccine by the end of
December.
Pre-clinical experiments of the vaccine have been completed,
said the official.
China has produced about 1,400 shots of the vaccine, and another
20,000 shots will be packaged and inspected by quality control
experts, Yin said.
He said tests of the vaccine on monkeys showed it was effective
in fighting against SARS infection after the animals were exposed
to the virus, and no serious side effects.
Yin Weidong, general manager of Beijing Kexing Bio-product Co.,
the developer of the vaccine, said an application for clinical
tests had been submitted to the State Food and Drug
Administration.
Yin Hongzhang said the drug administration would process the
application for clinical tests as quickly as possible.
Scientists with the company began to develop the vaccine at the
end of April this year after the outbreak of SARS on the Chinese
mainland.
Medical experts around the world have warned that SARS might
return, and China remains on alert against the disease.
The Ministry of Health said there have been neither clinically
confirmed nor suspected SARS cases on the Chinese mainland since
Aug. 16, when the last SARS patient on the mainland was discharged
from hospital.
