The first coronavirus vaccine tested on humans has produced positive results, with a small number of people who were tested showing an immunity against the virus. In an article by Medscape, drugmaker Moderna said the vaccine called mRNA-1273 “was generally safe and well tolerated.” The company said it plans to move ahead with the next two phases, in which larger numbers of people will be tested.

The vaccine uses what is called the messenger RNA approach, and it does not require a virus to make the vaccine. “I think the totality of science tells us that this is the right antigen and it should be protective,” Tal Zaks, Moderna’s chief medical officer said. The testing is being done in coordination with the National Institutes of Health and the National Institute of Allergy and Infectious Diseases.
