Inovio Pharmaceuticals is based in Pennsylvania, but scientists in its laboratory in San Diego made the discovery.
"We have an algorithm which we designed, and we put the DNA sequence into our algorithm and came up with the vaccine in that short amount of time," Inovio's research and development director Dr. Trevor Smith told KVUE.
Inovio's vaccine for COVID-19, as health officials have named the virus, could be ready as early as this summer. Inovio's stock jumped to $5.32 a share a few days after the company announced it was selected to work on a coronavirus vaccine. Shares are now at $3.34, back to where they were a month ago.
The American company is partnering with Beijing Advaccine, a Chinese company, to work on the vaccine.
