A researcher works on a vaccin against the new coronavirus COVID-19 at the Copenhagen's University research lab in Copenhagen, Denmark, on March 23, 2020. At Copenhagen university, a team of about 10 researchers is working around the clock to develop a vaccine against Covid-19 that could apply for clinical trial before within nine months. The vaccine will be based on two components : the protein which is on the surface of the coronavirus, called the spike protein that researchers express in the lab and then attach it on the surface of a virus-like particle.
