Some researchers are convinced that at least one AIDS vaccine will be ready by 2021. This would then be a real evolution insofar as patients who have been able to completely recover from AIDS are extremely rare.
According to an NBC News article published on December 1, 2019, the HVTN 702 vaccine appears to be the best candidate. The latter is also the oldest being tested, based on an earlier vaccine – RV144 – which had been shown to be effective but not sufficiently. Indeed, it reduced the infection rate but at a rate of only 30%. However, American researchers from the National Institute of Allergy and Infectious Diseases (NIAID) believe that HVTN 702 could reach 50% . Launched in South Africa in 2016, this vaccine was approved after the failure of RV144.
For the Department of Public Health in San Francisco (United States), this is a time for optimism. Indeed, there are three vaccines in total which are currently being tested. Besides the HVTN 702, there is also the Imbokodo and the Mosaico. However, these last two vaccines have not yet reached the advanced stage of HVTN 702.
The formulas of these two other vaccines are quite similar and require a total of six injections. Currently, the Imbokodo is passing its second test and the Mosaico its third. In addition, you should know that the first stages of the tests are decisive . If these show promise, then it will become possible to conduct an efficacy study.
In any case, the development of the three vaccines mentioned seems rapid, but failure may well occur, as has already happened. However, the researchers are confident and it will be necessary to follow the progress of the tests to be sure. In the event that one of the vaccines actually works, this could be a lead in order to develop an even more effective one in the future.
In a publication of November 15, 2019, the WHO recalled that nearly 38 million people were living with HIV in 2018. To date, more than 32 million deaths have been reported. Finally, let's mention the fact that in 2015 Bill Gates estimated the discovery of a cure for AIDS by 2030.
