US biotechnology firm Moderna says lab studies show its COVID-19 vaccine will provide protection against variants of the coronavirus first identified in the United Kingdom and South Africa.

“The study showed no significant impact” on the level of neutralizing antibodies elicited against the UK variant, B.1.1.7.

A sixfold reduction in antibody levels was observed with the B.1.351 variant first seen in South Africa, but the levels are thought to remain above what is required for protection against COVID-19.
