There seems to be a glimmer of hope in the fight to protect people from the Hiv -1, the most prevalent and contagious type of virus in the world.
The vaccine appears to be safe to use and manages to induce an immune response in humans and macaques in its early experimental phases, as published in the scientific journal Lancet.
This means that it is considered safe enough to proceed to the next experimental phase involving larger numbers of human beings. It turns out to be one of 5 experimental vaccines that have managed to reach this stage for 35 years of fighting HIV.
With 1.8 million new cases of acquired immunodeficiency syndrome per year, according to UN estimates and about 37 million people worldwide, seeking a vaccine seems urgent and extremely difficult.
Scientists use these early experimental steps to determine the best dose to use and to evaluate its safety. it was tested on 393 healthy people considered to be at low risk of infection and 72 monkeys. Participants come from 12 clinics in South Africa, East Africa, Thailand and the United States
In addition to being well tolerated by all subjects involved and generating an immunological response against the HIV-1 virus, the vaccine has 67% of protection against viruses in the monkeys provided. We still do not know if it can offer protection even in humans.
" I can say that we are satisfied with the results so far, but we must interpret the data with caution.We must realize that the development of an HIV vaccine is a unprecedented challenge and we still do not know if he will be able to protect men "said Dr. Dan H. Baraouch researcher in this study, Harvard Medical Professor and Director of the Center for Virology and Immunization Research Project
The new vaccine has shown for the moment its efficacy in monkeys and although it is capable of producing antibodies against HIV in humans, its degree of protection against infection
The second phase will involve a large number of people at high risk of infection
" Despite all the progress made in the fight against HIV, we need a vaccine. There is still a long way to go, it's nice to see that there is solid scientific evidence that allows us to move on to the next experimental phase ", he finally said. Dr. Carlos del Rio, who conducted a similar study in the Emory-CDC Experimental Vaccine Research Group.
