Biologist explained immunity problems against coronavirus

Doctor of Biological Sciences, professor at the GMU School of Systemic Biology (USA) Ancha Baranova said that only 7-8% of patients with a coronavirus develop long-term and strong immunity, and therefore it is difficult for society to develop collective immunity, and the disease can spread as much as possible wide.

“We have people who have been ill, they had fever and cough, but they don’t have antibodies to coronavirus, about 7-8% of such patients,” Baranova said in an interview with RIA Novosti.

“This means that they got rid of the infection with the help of interferons, which are quickly produced in the human body in response to the virus. In this case, the interferons themselves coped, and the antibodies did not arise, so these patients have no immunity to COVID-19, ”she explained.

In addition to 7-8% of people with a large number of antibodies and very strong immunity, as well as 7-8% who have been ill without antibodies at all, the remaining 85% of patients acquire immunity of varying degrees of strength, but their blood is not suitable for treating other people from COVID-19.

“There are super-people who have such a powerful immune response that their antibodies can be used to treat other people with plasma convalescent, which is done,” said the biologist, referring to the data of Professor Fan Wu from the Shanghai Medical Center and some other scientific institutions.

However, often the most stable immunity is given to patients in whom the course of the disease was severe, and they are not able to donate blood to those in need until they undergo rehabilitation after the disease. It’s dangerous for older people to donate blood.

“All this is a consequence of the simple thing that people are different and suffer the disease in different ways. Scientists have found that older people who have suffered a severe course of COVID-19 have stronger immunity, ”Ancha Baranova explained.

Recall recently the low immunity of mankind to COVID-19 was also noted by specialists of the World Health Organization (WHO). According to the organization, antibodies to coronavirus infection are produced in the body by no more than 10% of patients with the disease. Experts still do not know if this is enough to develop the so-called collective immunity.
