Some viral-vector vaccines may cause more harm than good

Leading efforts to create an HIV vaccine have hinged on the use of viruses as carriers for selected elements of the HIV virus. Recently, however, evidence has emerged that some of these so-called viral vector systems may undermine the immune system and should not be used for vaccine development.
