...generally slow-moving cancer of the immune system that affects roughly 5,000 Spaniards each year, presents an especially enticing target for vaccine researchers because its cells all carry a protein, called an idiotype, that distinguishes them from their healthy counterparts. Mixing the idiotype with other substances that trigger immunological responses, "the vaccine presents a tumor protein to the patients in such a way that their immune systems recognize it and destroy any cells bearing that protein," explains Larry Kwak, associate director of Cancer Immunology Research at Houston's MD Anderson Cancer Center and a leading vaccine researcher...
...vaccine for follicular lymphoma is not new. Stanford University's Ron Levy pioneered the effort more than 25 years ago, demonstrating that anti-idiotype antibodies could be produced in a laboratory and used to create a vaccine for humans that would trigger an immune response. In 1999 Kwak, then working at the National Institutes of Health (nih), modified the vaccine in a way that makes it easier for the immune system to recognize. His results were striking: the vaccine eliminated the residual tumor cells left after chemotherapy in 15 of his 20 patients. Now Bendandi, who worked with Kwak...

Lebanon already houses 400,000 permanent Palestinian refugees, some of whom have lived here for almost 60 years without gaining citizenship. Tension over their presence helped trigger the civil war that ran from 1975 to 1990. "In general, every time you have new refugees, no matter what the number, it raises the Palestinian question," says Stephane Jaquemet, the U.N. High Commission for Refugees representative in Lebanon. Still, the U.N. has worked out an agreement with the Lebanese...
