According to foreign media reports from 2 February local time, a new mutant strain of coronavirus Covid-19 E484K, widespread in the UK, is currently undergoing new mutations, that could reduce the effectiveness of the new coronavirus vaccine. This mutation has also been found in new strains of coronavirus in South Africa and Brazil..
This new mutated coronavirus strain is called E484K and is one of the mutated viruses, caused a new wave of powerful infections in South Africa and Brazil. Scientists believe, what, reshaping viral spike protein, it protects the virus from being recognized by the immune system, caused by vaccines or early new coronavirus infections, and makes antibodies ineffective.
The continued emergence of new variants of the new coronavirus may complicate the fight against the epidemic, because it indicates, that the vaccine will need to be updated regularly.
This is bad news for the effectiveness of the vaccine - commented Joseph Fovey, investigator-epidemiologist, Yale School of Public Health.
Development of the British mutating strain E484K
Julian Tang, viral expert from the University of Leicester in the UK, described the Covid-19 mutation in E484K as “alarming, although not entirely unexpected ". He said, that the public should abide by lockdown rules and reduce infections, to prevent further mutation of the virus.
Otherwise, the virus will not only continue to spread, but will continue to develop. Letting the virus spread. wide can provide a melting pot for various emerging options.
However, from 214 159 virus samples, currently tested by the United Kingdom Department of Health, only 11 samples were found with E484K mutations, which means, that mutations are not yet widespread.
UK authorities begin to take measures to control the spread of the mutant novel Covid-19 coronavirus. In parts of England, emergency testing for mutant virus has begun, discovered in South Africa, and imposed travel restrictions.
Besides, experts said, what, although the E484K mutation may reduce the effectiveness of the new corona vaccine, currently on the market, it does not mean, that the Covid-19 vaccine has expired.
According to the report, researchers are currently investigating the possible impact of new mutations on existing vaccines. Current vaccines mainly target the first few strains, caused a new corona epidemic.
British experts said, that even if the worst is planned, the vaccine can be recycled, and if necessary, the vaccine can be adjusted within a few weeks or months, to better adapt to the new situation.
American expert on infectious diseases Fauci previously stated, that as many people as possible should be vaccinated against the new corona as soon as possible. Although the effectiveness of vaccines against variant strains may be weakened, they can still protect infected people from developing serious illnesses. or even death.
