NEW YORK (REUTERS) - The mRNA vaccine from Pfizer and BioNTech may be less effective than Moderna's against the Delta variant of the coronavirus, according to two reports posted on medRxiv on Sunday (Aug 8) ahead of peer review.
In a study of more than 50,000 patients in the Mayo Clinic Health System, researchers found the effectiveness of Moderna's vaccine against infection had dropped to 76 per cent last month - when the Delta variant was predominant - from 86 per cent early this year.
Over the same period, the effectiveness of the Pfizer/BioNTech vaccine had fallen to 42 per cent from 76 per cent, researchers said.
