* VRC01 was shown around a decade ago to be one of several antibodies generated...that achieves broad neutralisation of several HIV strains
* 97% of participants who received an HIV vaccine immunogen candidate developed VRC01-class IgG B cells, precursors to broadly neutralising VRC01-class antibodies
* Results from another set of studies presented at HIVR4P (the Antibody Mediated Prevention [AMP] trials) showed that although intravenous administration of the VRC01 antibody at 8-week intervals did prevent infections with some strains of HIV, only 30% of the strains circulating in the trial regions of sub-Saharan Africa, South America, Switzerland, and the USA were sensitive to VRC01
To me this appears to be a great breakthrough but doesn't seem like a silver bullet.
