Coronavirus: Scientists race to develop a vaccine We've been here many times before. ln the past five years alone, lhe world has faced outbreaks of Ebola, Zika, another coronavirus called Mers (Middle East Respiratory Syndrome), and now lhe virus simply known as "2019-nCoV'. lt's already infected thousands of people and killed more than 100. But unlike in many previous outbreaks, where vaccines to protect people have taken years to develop, research for a vaccine to help stem this outbreak gol under way within hours of lhe virus being identified. Chinese officials released its genetic code very quickly. That information helps scientists determine where lhe virus probably carne from, how it might mutate as lhe outbreak develops, and how to protect people against it. With technological advances and greater commitment from governments around lhe world to fund research on emerging diseases, research facilities were able to spring into action fast. At lnovio's lab in San Diego, scientists are using a relatively new type of DNA technology to develop a potential vaccine. "INO-4800" - as it's currently called - with plans for it to enter human triais by the early summer. Kate Broderick, senior vice-president of research and development at lnovio, said: "Once China had provided lhe DNA sequence of this virus, we were able to put it through our lab's computer technology and design a vaccine within three hours. Our DNA medicine vaccines are novel in that they use DNA sequences from the virus to target specific parts of the pathogen which we believe the body will mount lhe strongest response to. We then use the patient's own cells to become a factory for lhe vaccine, strengthening lhe body's own natural response mechanisms." lnovio says if the initial human triais are a success, larger triais would follow, ideally in an outbreak setting in China by the end of lhe year. li is impossible to predict whether this outbreak is likely to have ended by then. But if lnovio's timeline goes to plan, the company says it will be lhe quickest a new vaccine has ever been developed and tested in an outbreak situation. The last time a similar virus - SARS - emerged in 2002 - China was slow to let the world know what was happening. So by the time work on a vaccine started in earnest, the outbreak was almost over. The work in these labs is being funded by the Coalition for Epidemie Preparedness lnnovations (Cepi), which is made up of and funded by governments and philanthropic organisations from around lhe world. li was created in the aftermath of lhe Ebola outbreak in West Africa to provide funding to accelerate lhe development of vaccines for new diseases.
