The global Epidemic of Wuhan pneumonia (Chinese communist virus pneumonia) continues to be fought in various countries. According to official data compiled by AFP, as of 11:00 GMT on the 16th (7:00 p.m. on Taiwan‘s 16th), at least 2.48 million people have died from Wuhan pneumonia (CCP pneumonia) and at least 194.07 million people have been infected. The U.K., which is fighting a new wave of the variant, has just reached the “major milestone” of 15 million people at highest risk of infection receiving the first dose of the vaccine and is ready to start the next phase of the vaccination program. However, according to The Guardian, a new variant of Wuhan pneumonia (CCP) has been discovered in the UK, with a worrying set of mutations, and has now spread across 10 countries.
The report mentions that according to a study by the University of Edinburgh, 23 cases of the new variant of the virus B1525 have been found in the UK so far, and cases have been reported in Denmark, the US, France, Australia, Canada, Jordan, Spain, and Nigeria and Ghana in Africa, with the original genetic sequence traced back to the strains that appeared in the UK and Nigeria last December. The new variant has genomic similarities to the B117 strain previously found in Kent, England, and has a disturbingly severe set of mutations, including an E484K mutation in the spine protein, which is located at the periphery of the virus and is thought to be critical for entry into human cells, and which occurs in both the South African and Brazilian variants of the virus.
Simon Clarke, a professor at Riding University, said that although it is unclear whether the mutation will change the chance of infection or the severity of the disease after infection, the E484K mutation in the South African variant of the virus has led to a degree of resistance to some vaccines. virus should be a priority until more is known about the Variant virus. And the new variant, B1525, should also be on the radar for enhanced screening. He said, “We don’t yet know how widespread this (new) variant of the virus is, but if there is mass transmission, it is predictable that the effectiveness of any vaccination or previous vaccination will be compromised.”
The BBC recently reported that experts working with Public health England highlighted that the E484K mutation has only been found on a small number of British variants of the virus, with only 11 cases out of 214,159 samples tested. Although this mutation may reduce the effectiveness of the vaccine, the vaccine currently in use should still work. However, the Israeli Ministry of Health said on the 14th that two more patients who had recovered from the epidemic had recently been infected with the South African variant for the second Time, bringing the total number of similar cases to three. The mutation may affect the antibodies produced by the vaccine to recognize the variant virus, resulting in the inability to activate the body’s immune system to attack and kill the virus.
