Variation SARS-CoV-2 has these three characteristics! Or disable the vaccine?
2020-12-23
On the 21st, horário local, many British scientists said in a briefing that after checking a number of data, they are now “very convinced” that this variant virus strain is easier to spread than other virus variants spread in the UK.
According to comprehensive reports, recently, a mutated SARS-CoV-2 was discovered in Britain, and the virus may appear in September, which led to an increase in infection rates in many places, and triggered more than 40 countries and regions around the world to “seal off” the UK. Por outro lado, although many British scientists said that mutated SARS-CoV-2 was easier to spread, WHO officials said on the 21st local time that mutated SARS-CoV-2 was not out of control and could be controlled by existing measures.
The British Broadcasting Corporation (BBC) reported on the 21st that the mutated virus was first discovered in September 2020. Statistics in November showed that one quarter of confirmed cases in London were related to the variant virus. By mid-December, the figure was close to two-thirds.
The BBC cited that the following three points have been combined and attracted people’s attention:
It is rapidly replacing other SARS-CoV-2 versions;
Importantly, it can partially affect the SARS-CoV-2 mutation;
Some mutations have been tested in the laboratory, which enhance the ability of virus to infect cells;
These factors lead to the emergence of a variant SARS-CoV-2 with stronger transmission power. The virus strain is abnormally highly mutable, and the most likely explanation is that it appears in patients who can’t resist the virus and have weak immune system. The most worrying point is whether it will avoid the antibody effect that the vaccine hopes to produce, and lead to the vaccine losing its efficacy.
On the same day, French Health Minister Willan also said that the variant SARS-CoV-2 has the possibility of spreading in France, and the French health department is conducting relevant research on the virus. De Christian Drosten, a well-known German virologist and professor at Charite University Hospital in Berlin, pointed out that the mutation SARS-CoV-2 in Britain already exists in Germany.
