Recent research has shown that some subjects are able to develop antibodies capable of neutralizing HIV1 virus (the most common), which is beginning to think about a possible vaccine.


There are many years now and many encouraging news regarding HIV is concerned, but we have never finished and come up with the long-awaited step to eradicate this virus that has taken so many lives ahead.

Scientists from the University of Zurich and the University Hospital of Zurich discovered that certain HIV-positive patients developed antibodies that neutralized the virus. This happened specifically with some subjects who were infected with HIV-1, the most common strain. However, when developing the antibodies, they not only acted on that specific strain. It turned out to be so effective that it had action on almost all strains of the virus.

The scientists reveal that they carefully studied the blood samples of 4,500 infected with HIV. Among them, there were at least 303 possible “transmission pairs”. This meant that that amount could be infected with the same strain of the virus. Roger Kouyos, one of the authors of the study, commented on the importance of these 303 patients:

“By comparing the immune response of these pairs of patients, we were able to demonstrate that the HI virus itself influences the extent and specificity of antibody reactions.”

It was concluded that these antibodies ended up adhering to certain proteins found on the surface of the virus. That yes, they vary depending on the strain and the subtype of this. Finally, they concluded that a specific protein would be the one that would produce the body’s immune response.
