Genomic Analysis Uncovers New Targets for HIV Vaccine

... CHAVI studies should help individual laboratories across the world perform research to better understand the virus." When someone becomes infected with HIV, the amount of virus in the blood spikes as the virus multiplies. After this peak, the amount of virus in the blood, known as the viral load, graduall...
