COVID vaccine excitement builds as Moderna reports third positive result

By Thomas A. Smith

They say good news comes in threes. For the third time in a week, a coronavirus vaccine developer has reported preliminary results suggesting its vaccine is highly effective.

Today, biotech company Moderna in Cambridge, Massachusetts, reported that its RNA-based vaccine was more than 94% effective at preventing COVID-19, based on an analysis of 95 cases in its ongoing phase III efficacy trial.

But scientists say that the press-released results share a few more details than last week s positive announcements from Pfizer and BioNtech, which are together working on a rival RNA vaccine, and from Russian developers behind the controversial Sputnik V vaccine. Moderna released figures suggesting that its vaccine was likely to prevent severe COVID-19 infections, something that was not clear from the other developers announcements.
