For those recovering from "Corona": Do not secure the mutated strain of the virus

Clinical trials of a vaccine against the emerging corona virus revealed that people who were infected with "Covid 19" disease and then recovered from it are not completely safe from the mutated strain that appeared in South Africa, and then began to spread quickly.

According to the American "Washington Post" newspaper, these preliminary data prompt questions about possible ways to encircle the epidemic and bring it under control.

It is likely that many health experts, at the present time, that those recovering from "Covid 19" disease will be immune to infection for several months, given that they acquire antibodies during the infection period.

105 million people in the world have been infected with the Coronavirus so far, 2.3 million of them have died, while 77.5 million have recovered.

The director of the US National Institute of Allergy and Infectious Diseases, Anthony Fauci, believes that what appears at the present time is that the vaccine is better at protecting humans from infection, compared to natural infection.

Earlier, natural infection with the virus and then recovery from it were seen as a step towards acquiring antibodies to the disease, and therefore, it appeared as a contribution to achieving herd immunity and what is known as "herd immunity."

Fauchi believes that what the study revealed, constitutes a great incentive to initiate vaccination, after the recovered people thought that they had become immune.

And when clinical trials were conducted for the "Nova Fax" vaccine, and a placebo dose of the vaccine was given, or what is known as "placebo", it was found that people who had recovered from "Covid 19" but were still susceptible to infection with the mutated strain that appeared in South Africa and is known scientifically as "B.1.351." ".

The principle of a fake dose is to give someone an empty dose of the vaccine, that is, not to give him any substance, but without knowing it, and the goal is to compare his situation with that of the rest of the volunteers in the experiments, to ensure the effectiveness of the vaccine.

The mutated strain became the most common in South Africa, while it was detected in limited locations in the United States.

But these results, which were published on an experimental vaccine in South Africa, do not receive a scientific consensus, because they were based on data that were described as limited.

Researchers disagree about the degree of danger the new strains pose, and whether they are actually able to resist vaccines developed so far.

Fauci acknowledges that the immunity that a person recovering from the emerging corona virus gets after recovering, is not sufficient to prevent infection with the mutated strain.

He explained that the level of immunity may not be sufficient, whether it relates to the degree of immunity, its intensity, or the period of time it lasts.

And an expert in virology at Georgetown University, Angela Rasmussen, says that what she fears is that people will fade out hope because of these initial results: “I fear that the message they receive is that we will not get rid of this matter (that is, the epidemic) forever,” she explained. While the data does not explicitly say these things. "

Rasmussen and other researchers indicate that there are no severe symptoms in people who become infected again with the Coronavirus, and she adds that there is not enough evidence so far that people are infected with the Corona virus for a second time after a full recovery.
