Rey According to established scientific dogma, infection of cells with HIV-1 leads to delivery of the viral capsid into the cell cytoplasm, followed by “uncoating” of the capsid to release the single-stranded RNA genome.

The Problem of Original Antigenic Sin

The second exposure will immediately lead to …
