Serum Neutralizing Activity Elicited by mRNA-1273 Vaccine

Abstract
The mRNA-1273 vaccine against SARS-CoV-2 elicited high neutralizing-antibody titers in phase 1 trial participants1,2 and has been shown to be highly efficacious in preventing symptomatic Covid-19 disease and severe disease.3 The recent emergence of SARS-CoV-2 variants in the United Kingdom (the B.1.1.7 lineage) and in South Africa (the B.1.351 lineage) has led to concerns about increased transmission and the potential of these variants to circumvent immunity elicited by natural infection or vaccination.
