Of the 196 Covid-19 cases in the trial, 185 were in the placebo group and only 11 in the vaccine group, Moderna reported.Even more important, the vaccine — called mRNA-1273 — appears to protect against severe disease, not just asymptomatic or mild cases. Of the 30 severe Covid-19 cases among trial participants, all occurred in the placebo group. If the finding is real, it would likely mean averted deaths and hospitalizations when millions of people are immunized.“You’ve got 100 percent protection against severe disease,” Paul Offit, an infectious disease and vaccine researcher at Children’s Hospital of Philadelphia, told Vox. “That’s remarkable.”“If these numbers are right, it’s more than we’d need for the vaccine to be a major control measure for this outbreak,” said Eric Rubin, an infectious disease specialist and the editor-in-chief of the New England Journal of Medicine.Moderna’s CEO, Stéphane Bancel, said in the press release that the company plans to request an Emergency Use Authorization from the Food and Drug Administration, which would allow the vaccine to be used in limited cases for people facing some of the highest risk of exposure to Covid-19, like health care workers. “We believe that our vaccine will provide a new and powerful tool that may change the course of this pandemic and help prevent severe disease, hospitalizations and death,” he added.
