In the framework of the 10 World Scientific Conference on HIV (IAS 2019) in Mexico City, the vice president of the Center for Technology, Biomedical and Environmental Research in Lima, Peru, said that these vaccines could be effective for some strains of this Virus.
The idea is that with this new tool the spread of this epidemic can be stopped by at least 65%.
The vaccine has inserts from some parts that resemble parts of the virus, so the ability to be effective for different strains or types of HIV is high. Sanchez said, which is part of the researchers of this study.
The development of the vaccine has been 12 years and was tested on apes, so there have been studies in phase 1, 1b and 2a, which are prior phases to evaluate efficacy in humans.
The study is called mosaic and will be conducted by researchers from the National Institute of Allergic and Infectious Diseases, the National Institutions of Health, the HIV Vaccine Test Network and the United States. There. Army Medical Research and Development Command.
The investigation, which will begin in September, will be conducted in 3,800 people from Argentina, Brazil, Italy, Mexico, Peru, Poland, Spain and the United States. There. Of 55 clinical locations around the world, 125 of Mexico's cities will be exchanged.

We are determined to develop an effective HIV vaccination worldwide to reduce the trajectory of 1.5 million new infections. Hiv is estimated to be happening every year, said Larry Kori MD, principal investigator of the HVTN, Virologist and member of the Fred Hutchinson Cancer Research Center in Seattle.
The study reported that half of the patients would receive a placebo and the other half would be divided into four doses containing Adenovirus Serotype 20, which would provide mosquito antigens against HIV.
The antigens will serve to activate the immune response of the individual to the virus.
Sanchez did not add the virus as such, they are pieces of modified virus that will identify HIV and fight it so that it cannot reach any part of the body.
Saxie said the vaccine, It has been tested for several centuries in previous phases and has results without major undesirable effects.

There are several tools to prevent HIV. We have had this condom for decades, but in the implementation it has not been used enough, there is a precautionary prophylaxis (prep) and vaccine would be an additional tool, he said.
The vaccine study and development is sponsored by the pharmaceutical company Janssen, And although it is expected that within four years you can have clear results about its effectiveness, it is not yet considered when it may be available to the general public.
