Moderna says it believes vaccine will work against new variants
(Reuters) – Moderna said on Monday it believes its COVID-19 vaccine protects against new variants found in Britain and South Africa, although it will test a new booster shot aimed at the South Africa variant after concluding that the antibody response could be diminished.
The company said in a press release that it found no reduction in the antibody response against the variant found in Britain. Against the variant found in South Africa, it found a reduced response but still believed its two-dose regimen would provide protection.
Moderna shares rose nearly 10%, or $12.40, to $143.85 in morning trading.
The emergence of new variants in Britain, South Africa and Brazil has created some concern that mutations in the virus may make vaccines less effective.
Jefferies analyst Michael Yee said in a research note that it was encouraging that the Moderna testing showed that even against the variant found in South Africa, the antibody response produced by its mRNA-1273 vaccine was still “above the levels” that provide protection.
