A promising new approach to a live attenuated HIV-1 vaccine is being pursued by scientists, using a genetically modified form of the HIV virus. The new method involves manipulating the virus' codons -- a sequence of three nucleotides that form genetic code -- to rely on an unnatural amino acid for proper protein translation, which allows it to replicate. Because this amino acid is foreign to the human body, the virus cannot continue to reproduce, researchers report.
