There is 'promising pathway' for vaccine against Zika: Obama

WASHINGTON (Reuters) - U.S. President Barack Obama expressed optimism on Thursday about the possibilities for a vaccine against Zika, a virus he said turned out to be not especially complicated. "We just had a meeting about Zika, where we actually think there's a promising pathway for diagnostics and vaccines on this," Obama said during a panel discussion about precision medicine. "It’s not a real complicated virus, apparently." (Reporting by Jeff Mason; Editing by Susan Heavey)
