Virologists fear, that soon this variant of the infection may stop responding to the vaccine
Rospotrebnadzor on the first working day after the New Year holidays reported important news: in the Novosibirsk center "Vector", where the vaccine against COVID-19 was developed, выделили British strain of coronavirus. We asked Alexander Chepurnov, Leading Researcher, Institute of Clinical and Experimental Medicine, explain, what does it mean, and how such a strain threatens Russians. In the past, Chepurnov himself headed the laboratory at "Vector", and is now studying coronavirus at another institute. We asked an expert, what does the statement of Rospotrebnadzor mean and what to expect.
Речь о том, that the strain was isolated: means, was a Russian, who got sick in England and flew to Russia, or someone from the Russians had contact with a sick person from England in another country. Most likely, it was a patient from Moscow, because there are very close contacts with Europe. When he was tested for coronavirus, then during the survey he talked about contacts with the British. And when he confirmed the coronavirus, then his analyzes were sent to "Vector". And it is right: obtaining similar samples in a pandemic situation is important for any laboratory in the world.
Он более заразный!
The mutation in this strain occurred precisely in that part, which is responsible for the ability to "join" cells. This makes more people infected with the virus.. But, as with the usual coronavirus, post-covid immunity develops in those who have been ill, that is, antibodies are produced in the same way as in the usual COVID-19.
Yes, the vaccine is precisely aimed at that site of interaction between the virus and healthy cells, where did the mutation occur. The vaccine will also protect against the British strain. But not for long.
Есть пациенты, who are asymptomatic with coronavirus. And if such a person, already infected with the British strain, graft, then the virus will have to get used to new conditions, adapt. And a moment like this may come, when he stops responding to the vaccine.
It `s that, which epidemiologists and virologists are now very afraid of.
То, that this variant of the virus will begin to spread around the world, it was inevitable. Since it is biologically stronger than the strain we are used to, then it will gradually replace it, means, more people will get infected.
It turns out, if the recovered hurry up with vaccination, then the vaccine will simply be neutralized by antibodies in the body (more details).
An unusual side effect appears after two to three months: you can overcome it by means, which you can easily find at the pharmacy (more details).
It turns out, with green tea and black chokeberry, a person can harm himself, but echinacea, which everyone feared, help to strengthen the immune system (more details).
You will not believe, but the cure for the infection all this time grew on a birch (more details).
The next stage of the virological experiment is taking place in the medical boxes of "Vector". The effect of the drug from the coronavirus is tested in humans (more details).
Novosibirsk professor risked his own health and told, what a person feels, suffering from covid repeatedly, and also what conclusions virologists can already draw (more details).
