COVID-19: Confirmed’effectiveness against Omicron strain BA-2′:
-Confirmed by the University of Tokyo-
Omicron strain ‘BA-2’
The efficacy of the new coronavirus against the mutant strain Omicron strain “BA.2” was confirmed.
Research teams such as Tokyo University:
“Neutralizing antibody drugs and antiviral drugs approved as corona treatments in Japan” are effective.
The research team at the University of Tokyo confirmed it in a cell experiment.
Tokyo University Research Team:
It was published in the New England Journal of Medicine, a US medical journal, on the 10th.
Subspecies of Omicron strain:
For Omicron strains,
BA -1 and BA-2, etc.
There are multiple subspecies with different gene sequences.
Currently, BA.1 is the mainstream in the world including Japan.
Denmark and India:
BA-2, which may be more infectious, has become the mainstream.
There are concerns about replacement in Japan as well.
Verify the effectiveness of “Rona Preve”:
The team used cultured cells to verify the efficacy of the therapeutic agent against BA-2.
as a result,
“Lonapreve, which is a combination of two antibodies, kasiribimab and imdebimab,”
“Sotrovimab, a neutralizing antibody drug,”
It was confirmed that the effect of inhibiting infection to virus cells was high.
again,
With the antiviral drug remdesivir,
Molnupiravir and
Also about Nirmatrelville
“The effect of suppressing the growth of virus cells has been confirmed,” he said.
Rona Preve:
In the past experiments of the research team, “a significant decrease in the effect on BA.1” was confirmed.
From this result, it is stated that “a certain effect was confirmed in BA.2”.
Efficacy comparison:
Compared to its effectiveness against conventional strains
Antiviral drug:
Antiviral drugs reduced the virus by up to one-third.
Antibody drug:
On the other hand, antibody drugs
Rona Preve is 1/63,
Sotrovimab is 1/50,
The viral load has decreased.
