Moderna Says Vaccine Protects Against All Known Variants

Moderna (NASDAQ: MRNA) announced evidence that its COVID-19 vaccine is protective against all variants of the SARS-CoV-2 virus detected to date, including two strains first detected in the United Kingdom and South Africa. The level of protective antibodies against the U.K. strain, B.1.1.7, was equivalent to those against earlier variants. Moderna's study was conducted in the laboratory by exposing blood serum from eight clinical trial participants aged 18 to 55 who had received the two-dose regimen of its mRNA-1273 vaccine and from two nonhuman primates to all key emerging variants of SARS-CoV-2.
