Follow RT on US biotech firm Moderna said on Monday that it was starting trials for another Covid-19 vaccine to immunize people against a mutant strain of the virus recently discovered in South Africa.
The company also said laboratory tests had shown that two doses of its current Covid-19 shot are effective against the variant, known as 501.V2, as well as the B.1.1.7 strain of the virus found in Britain late last year.
Moderna did stress, however, that the immune response generated by the vaccine appeared to be six times weaker against the South African variant compared to the previous Covid-19 strain, although with antibody levels still above the threshold required for protection.

REFILE-COVID SCIENCE-Moderna shot protects against new virus variants; higher blood thinner dose keeps patients off ventilators Reuters 1/25/2021

Jan 25 (Reuters) - The following is a roundup of some of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus.
Moderna vaccine protects against new variants
The COVID-19 vaccine from Moderna Inc protects against the new virus variants found in Britain and South Africa, researchers reported on Monday on bioRxiv ahead of peer review. They found no reduction in the effect of vaccine-induced antibodies on the UK variant. They did see significantly reduced effectiveness of the antibodies on the South Africa variant, although Moderna still believes its two-dose vaccine will provide protection. The company said it will test a new booster shot aimed at the South Africa variant that could be made available if necessary. Dr. Paul Offit o
