President Barack Obama completed a two-day trip to Guadalajara, Mexico, where he took part in a summit—dubbed the Three Amigos' summit—with Mexican President Felipe Calderon and Canadian Prime Minister Stephen Harper. The three met today to discuss, among other things, their commitment to fighting swine flu and climate change. In a joint statement, they said their countries will collaborate to combat the threats.
Back in the United States, Human trials of a vaccine against the H1N1 (swine flu) virus began today at Atlanta’s Emory University's Hope Clinic. The plan is to inject roughly 25 volunteers with the vaccine over the next five days. As flu season approaches, researchers hope to determine not only the vaccine's safety and effectiveness, but also whether one or two doses are required to produce full immunity to the disease. Experts are expecting a resurgence of H1N1 cases in the fall, and The World health Organization believes a vaccine could be made available to the general public as early as September.
