New Variation Occurs in Mutated CoV-19 Reported
The
mutated CoV-19 reported in the UK has a
new mutation, which may avoid the immune system attack
According to British Sky News Channel on the 2nd, British health experts have observed a
new mutation in some samples of mutated CoV-19 previously reported in Britain, which may help the virus avoid the attack of human immune system.
According to the report, the Public Health Bureau of England called this
new mutation observed in virus samples E484K. This mutation has been previously observed in the mutant viruses reported in South Africa.
Jonathan Stoje, Ph.D., Francis Crick Institute, UK, said that researchers had observed the same mutation, E484K mutation, in the
mutated CoV-19 discovered in Brazil and South Africa respectively. From the virological point of view, mutation is not unexpected, and whether mutation will bring great growth advantages to virus needs further observation.
It may affect vaccine efficacy. CNN quoted experts as saying that this new discovery may mean that this
variant CoV-19 is not only more infectious, but also has a certain degree of drug resistance to the immune protection provided by vaccines, or makes people who have been infected with the virus more likely to re-infect. It is not groundless to infer that the vaccine efficacy is weakened due to the mutation and re-mutation of CoV-19. Studies have shown that E484K mutation may be the key reason for the poor efficacy of some vaccines in South Africa.
Highlight the complexity of epidemic prevention and control. At the same time, government officials and experts said that it was too early to predict whether the mutation and
re-mutation in CoV-19 would have a significant impact on the development of the epidemic in Britain and the world. Reuters pointed out that the re-mutation of the mutated virus reported by the UK highlights the complexity of epidemic prevention and control, even in the context of vaccine launch and blockade by various countries. However, in view of the rapid spread of variant viruses, active detection, compliance with prevention and control guidelines and rapid introduction of vaccines are more important than ever.
"We need to vaccinate more people as soon as possible." Fauci previously said," Although the protection against these mutated viruses has weakened, there is still enough protection to prevent patients from suffering from serious diseases, as well as hospitalization and death."
Last December, the United Kingdom announced the emergence of a
variant CoV-19, and there is evidence that this virus is more capable of spreading (need a
