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. 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. Pfizer Inc and BioNTech SE have also said tests showed their vaccine is effective against the variant found in Britain, but have not yet disclosed results against the South Africa variant. Moderna said it plans to publish data from its tests against the variants on the website bioRxiv.
