A virus similar to SARS has spread through hospitals in Europe and the Middle East, prompting fears of human-to-human transmission. But health officials said vaccines were unlikely to play a role in controlling the outbreak, which has sickened 34 people and killed 18. Instead, they've focused on detecting the novel coronavirus, dubbed nCoV, and have quickly isolated patients. UTMB’s Thomas Ksiazek said “mindfulness” is key once again, as a vaccine for nCoV could take years to develop and test. “The thing that really takes time is the regulation aspect of it,” he said, describing the lengthy process of proving safety and efficacy in animal models before even thinking about testing in humans.
