By Philip Cohen in San Francisco COMBINING two approaches to an AIDS vaccine could provide a powerful weapon against the disease, tests on monkeys suggest. Many experts believe that effective immunisation against HIV requires the body to produce killer T cells, which destroy infected cells. This process starts when special cells display viral fragments, or antigens, to the immune system. Doing this with DNA vaccines has had some success but often doesn’t produce a strong enough immune response. Another strategy is to infect dendritic cells—the body’s most potent antigen-presenting cells—with a weakened form of the virus. Again,
