HIV vaccine trial was significant
"We now, after 26 years of trying, believe that we can go down that road with confidence that we will be able to develop a vaccine that is globally effective"
- Colonel Nelson Michael, US military HIV research program
A review of a trial of a HIV vaccine in Thailand has concluded that it does show real signs of a protective effect. Scientists announced last month that a combination of vaccines gave a 31% level of protection in trials among 16,000 heterosexuals aged 18-30.
Doubts had been raised about whether the finding was significant.
But new data published at a conference in Paris indicates that, while small scale, the findings are robust and statistically significant.
