Spanish scientists at the National Biotech Centre in Madrid say a new vaccine could reduce HIV to a “minor chronic infection.”
The researchers report that 90% of participants given the MVA-B vaccine showed an immune response to the virus and 85% kept the immunity a year later.
According to a press release from The Spanish National Research Council (CSIC):
The success of this vaccine, CSIC’s patent, is based on the capability of human’s immune system to learn how to react over time against virus particles and infected cells. “MVA‐B vaccine has proven to be as powerful as any other vaccine currently being studied, or even more,” says Mariano Esteban, head researcher.MVA‐B is an attenuated virus, which has already been used in the past to eradicate smallpox, and also as a model in the research of many other vaccines. The “B” stands for the HIV subtype it is meant to work against, the most common in Europe.
Once injected, the vaccine teaches the volunteer’s immune system to track down and fight off the virus. “It is like showing a picture of the HIV so that it is able to recognize it if it sees it again in the future,” Esteban says.
