Scientists to start on second phase on their HIV vaccine soon
The second phase of the of the experiments have already been approved by the national drug administration and trials will start in a few months. The trials on the HIV vaccine was part of the 16 major science and technology projects in the nation’s 5 year program that is making good progress. A vaccine that is needed to cure and infectious diseases must pass three phases of clinical trials to determine the effect of the vaccine on healthy people. The trials also test the effectiveness on the people that are exposed to a risk of infection and evaluate its impact.
A number of countries have already passed the second phase of the clinical trials, but none have passed the stage three of the trials. In 1993 china started their research on an HIV vaccine with conducting clinical trials with a vaccine that is produced outside of the country. 2005 saw Chinese scientists developed a new type of vaccine deprived from a smallpox vaccine as a carrier.
Right now around 740,000 people are infected with the HIV virus in China, and the number will increase to 1.2 million by the year 2015.
