[Reuters]— US moderna confirmed on the 25th that the new coronavirus vaccine developed by the company is effective against mutants detected in the United Kingdom and South Africa, but the effect may be weakened in South African species. Announced that it will conduct a test of a new vaccine booster for the same mutant.
As a result of the experiments conducted so far, the antibody reaction similar to that of the conventional species was confirmed in the mutant species confirmed in the United Kingdom, but the antibody reaction was weakened in the mutant species in South Africa.
