Three separate monkey studies managed to coax rare, hard-to-find B cells into producing the broadly neutralizing antibodies that HIV has evaded for forty years. The trick is sequencing the vaccine: prime the right cells first, then push them step by step toward the antibody you want. It is the closest anyone has come to a design manual for an HIV vaccine.
