China's AIDS vaccine tests going 'smoothly'
(AFP)
Updated: 2005-12-12 17:56 The second phase of the trials will test the immune nature and safety of the
vaccine, according to Chen.
There have been about 35 AIDS vaccine trials on humans throughout the world,
most of which are still in the first phase, according to Xinhua.
In the 24-year history of AIDS, only one vaccine has completed the full
three-phase trial process -- AIDSVAX, which was found to be a disappointing
failure.
In the latest trial to make headlines, Swedish researchers announced on
December 1 that their trial for a so-called DNA vaccine against the AIDS virus
was going better than expected.
The vaccine had successfully completed the first phase of tests among 40
Swedish HIV-negative volunteers, the Karolinska Institute in Stockholm said.
"It has been more effective than we thought it would be," the professor and
head of clinical testing at the institute, Eric Sandstroem, told AFP.
"We have also failed to find any vaccine-related side effects at all."
Karolinska professor Britta Wahren, who developed the vaccine, also expressed
optimism.
"There is every reason to be hopeful, even though the study is not finished,"
Wahren said.
