The National AIDS research Institute in Pune has put an end to the India's first and biggest, human trial of an AIDS vaccine.
The institute said that the first phase of the human trials, which started in 2005, has failed.
Thirty volunteers were injected with a vaccine, called the Adeno-Associated Virus Vector. But 80 per cent of the volunteers failed to respond to it.
NARI Director, Dr Ramesh Paranjape, said, "The immediate capacity of the vaccine that is to produce immune response was not found to be very high with this vaccine. Hence, we are not going to phase two of this vaccine."
The vaccine trial was divided into three phases:
Phase 1: 30 volunteers are tested with the vaccine
Phase 2: If the first phase produces desirable results, 500 volunteers are given the vaccine.
Phase 3: Thousands of volunteers are tested before certifying the vaccine as successful.
However, researchers are still positive.
“This is not the end of the road,” said Dr Paranjape, for another trial underway at Chennai's TB Research Centre may bring results that their vaccine test could not.
