The first phase clinical trial of HIV vaccine has been carried out successfully says Chinese scientists and will start the second phase trials in a few months.
Shao Yiming, chief expert of the National Center for AIDS/STD Control and Prevention, told that the second phase of experiments on the vaccine, which has been approved by the national drug administration, "is likely to start in three or four months", reports China Daily.
AdvertisementChina started research on an HIV vaccine in 1993 by conducting clinical trials with a vaccine produced outside the country.
In 2005, Chinese scientists developed a new vaccine using the smallpox vaccine as a carrier.
Smallpox was a deadly infectious disease that had been globally eradicated by the late 1970s.
"The smallpox vaccine has a long history and wide application, so we chose it for its reliability and its higher immunogenic potential," Shao was quoted as saying by the website of the central government, www.gov.cn.
Clinical trials of the new vaccine started in 2007 and, late last year, it was proved to be able to induce an immune reaction in the cells of healthy people.
"The smallpox vaccine has been used on hundreds of millions of people. All Chinese people under 25 have been vaccinated," said Shao, pointing out that this is a unique characteristic among the "more than 100 ongoing experiments in the world".
If the vaccine proves successful, it will have a huge impact on the nation's HIV prevention policy, Shao said in an earlier interview with China Central Television.
