UK Identifies 2 More COVID-19 Variants With Antibody-Resistant Mutation

British health authorities have identified two more COVID-19 variants with a mutation that makes them resistant to antibodies.

Over 4,000 variants of the CCP (Chinese Communist Party) virus, also known as SARS-CoV-2 or the novel coronavirus, have been identified across the globe, most of which are not of concern, the Public Health England (PHE) said.

But the two variants identified by the UK’s New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG) contain the E484K spike protein mutation, which has been found to result in weaker neutralisation by antibodies in laboratory experiments.

The E484K mutation is present on a number of variants found around the world, including the South African variant, which has been found to be more resistant to antibodies and reduces the efficacy of COVID-19 vaccines.
