The variant has the E484K mutation and is likely to have been brought in from abroad, officials said. The mutated strain is believed to be capable of “immune escape,” meaning it can evade the ...

An estimated 56.5 percent of the patients contracted a variant with the E484K mutation, which is feared to reduce vaccines’ efficacy. The two variants accounted for 89 percent of the infections ...

Tests show they have a mutation, called E484K, that is already seen in the South Africa variant. Although this change may reduce vaccine effectiveness, the current ones in use should still work ...

The Bristol variant contains the E484K mutation also found in the South African and Brazilian variants. Health officials in the city say getting as many people vaccinated as possible is key.

In the UK, A.23.1 is being formally investigated by Public Health England because it has the E484K mutation - the mutation that is found in the variant in South Africa, that scientists believe ...

N501Y and E484K mutations were earlier also found in Beta, Gamma, Theta and Omicron variants. “The mutation set and phylogenetic position of the genomes obtained here indicate based on our ...

But what makes this strain troublesome is two spike mutations - K417T and E484K - that are mostly missing in B.1.1.7 cases. (UK researchers did find 11 cases of B.1.1.7 with the E484K mutation in ...

These include the variants with the immune-escape E484K mutation and the one with the N501Y mutation found to have a higher transmission rate. While the E484K mutation is found in both the South ...
