Colonel Jerome Kim, who helped lead the study for the U.S. Military HIV Research Program, says other unknowns remain about the vaccine, such as the duration of its effect, the potential need for additional boosters, its efficacy in higher-risk populations like intravenous drug users and, most crucially, whether it might work on other subtypes of the virus. "The vaccine was tested in Thailand against types of HIV that circulate in Thailand," Kim says, pointing out that a different strain of the virus causes high infection rates in Africa...
Both Kim and Fauci emphasize that it will probably be a "significant period of time" before the trial results lead to a vaccine that can be submitted for approval for use in the general public, if such a breakthrough occurs at all. Most licensed vaccines have an efficacy rate of at least 70%, although it's possible that an HIV vaccine with lower efficacy may gain approval, Kim says. "The efficacy threshold may be a consideration that is specific to individual countries, the nature of their HIV-AIDS epidemics and the performance characteristics of the vaccine," Kim says...
...spun-out and wrecked behind them. The song is also hindered by its even-handed verse distribution; the transitions between singers make the song feel incoherent and contrived. The more-focused “Losin’ Yo’ Head”—with James taking lead vocals throughout—is catchier, but still comes across as uninteresting classic rock emulation. Oberst takes lead vocals on irritating country tracks that sound like pre-pubescent Johnny Cash imitations. On “Man Named Truth,” easily the album’s worst track, Oberst...
...much as engaging with the hope of overcoming those difficulties. Of course, many bands sing and play optimistically, but few manage to embody that positivity with the conviction that Pearl Jam does, most evidently on “The Fixer,” the album’s lead single and the song Bono wishes he could write. “When something’s broke, / I want to put a bit of fixin’ on it,” Vedder sings. The lyrics are reminiscent of Coldplay?...
...Germany prefers to promote its interests behind the scenes rather than to lead in proportion to its size and economic clout. With Merkel or without her, nobody expects much change in Germany's worldview. That means a pro-U.S. and pro-Israel stance, a pragmatic approach in dealing with Russia and China, and a faith in negotiations and sanctions to bring recalcitrant countries like Iran back into constructive dialogue. Just don't look to Berlin for big ideas or robust new approaches to international problems. "There has been a passive consensus on foreign policy issues," says Jan Techau, director...
