Vaccines have already been made against HIV but they don’t work in 100% of cases.
Last week, researchers injected the first of what they hope will be 5400 participants in the $130 million study in South Africa, which should show whether a combination of vaccines will protect participants from HIV infection. Scientists tried this vaccine combination in Thailand 7 years ago but found that it reduced the risk of HIV infection by only 31%.
What do you think of this? Maybe even preventing HIV in this small percentage of people would help South Africa, which has more than 6 million HIV-infected people ?
