The 2019 novel coronavirus continues to spread throughout the world. Since it first emerged in December, 2019-nCoV has infected more than 31,400 people, and at least 630 people have died from the illness, according to the most recent numbers from CNN. While the majority of those affected remain in mainland China, coronavirus has spread to over 25 countries and territories, infecting more than 320 people in those regions—the US itself currently has 12 confirmed cases of coronavirus.
As the outbreak heads towards possible pandemic status, scientists worldwide are on the hunt to formulate a coronavirus vaccine, with labs set up everywhere from the Philadelphia suburbs to the UK—but just how close are we to an effective vaccine becoming a reality?
