New vaccine shows promise against toughest HIV strains

A new study reports successful immunization against a so-far invincible “death star” strain of an HIV-related laboratory virus (SIVmac239) and another tough strain. The new approach also achieves long-term protection with a single dose, showing that gene therapy could allow broad and durable protection, based on a modified form of the CD4 protein that allows HIV entry into human cells.
