Over 200 people have died since 2019-nCoV emerged in China late last year.
Professor Brenda Hogue of the Biodesign Institute Center for Immunotherapy, Vaccines and Virotherapy at Arizona State University told:"It normally takes years to develop a vaccine and bring it to the point that it is approved for use in humans.
Dr. Peter Jay Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine in Houston, who is currently working on a coronavirus vaccine, toldwork by taking an, or parts of, an infectious agent and putting it inside the body. This stimulates the immune system so it learns how to fight off the pathogen, but without harming the individual.
"Once a potential vaccine platform is identified, it goes into research and development. After meeting safety, quality and efficacy requirements the vaccine goes into pre-clinical studies that include testing in animal models before moving onto clinical trials that generally consists of four phases, with testing in humans, to further assess safety and assessment of effectiveness and dosage requirements," she said.
However, Adalja said:"It may be possible to make a universal coronavirus vaccine if a common target can be found but I think the thrust will first be to make one targeted against 2019-nCoV."
