The new coronavirus has mutated more toxic? Zhang Wenhong's out of the world.

At noon today,Zhang Wenhong tweeted about the29% of the new crown virus samples are now D614G mutationsthere is no evidence to confirm that the D614G variant is more toxic
Zhang Wenhong said, "
recently everyone is concerned about whether the new coronavirus has mutated, causing a wider spread, and the vaccine is not yet on the market is also facing the threat of ineffective."especially on July 3, 2020, published in the internationally renowned magazine "Cells", showing that 29% of the new coronavirus samples have a D164G mutation, especially in Beijing this outbreak rebound found that the virus strain also has this mutation, the subsequent impact on China's epidemic will be how? Huashaninfectedthis article on the public number will answer the storyThe good news is that the current evidence does not confirm that the D614G mutant strain is more toxic, and that the D614G mutation is unlikely to have a significant impact on the efficacy of the vaccine currently being developedBut as the outbreak moves into deep water, there will be more uncertainty to follow, and more experimental validation and monitoring of the mutationarticle that the number of viruses introduced in China, which still dominates D614, has fallen sharply as a result of controlling the spread of imported casesAlthough the D614G mutant strain was found in the Beijing outbreak, the G614 virus lost the chance to expand significantly in China due to rapid and decisive prevention and control measuresthe article points out that some scholars have suggested that there is a strong correlation between D614G mutation and disease mortality, but still remains in statistical correlation analysisCurrent evidence suggests that D614G is less important toCOVID-19than other risk factors such as age or other underlying diseasesAs a result, the current evidence does not prove that the D614G mutant strain is more toxicon the effects of mutations on vaccines, the paper argues that the D614G mutation does not affect nucleic acid testing of the virusThe receptor binding region (RBD) of the prickly protein is the focus of many vaccines and therapies today, and D614G is not located in the RBD regionAt the same time, antibodies produced by naturally infected viruses containing D614 or G614 can be cross-neutralized, so for now, the D614G mutation is unlikely to have a significant impact on the efficacy of the vaccine currently being developedWHO has previously responded to D614G mutation
recently,laboratory study found that 29% of new coronavirus samples inhave D614G mutations,has been widely spread in Europe and the United States,mutation may enhance the spread of the virus!the World Health Organization responded on July 4th, saying that there was no evidencethat caused a more serious illness Source: Guangdong Health
