The biologist explained the lack of collective immunity to COVID-19 in Russia: Society: Russia: Lenta.ru
Ancha Baranova, Professor of the School of Systems Biology at George Mason University (Virginia, USA), Chief Researcher of the Laboratory of Functional Genomics of the Medical Genomics Research Center of the Russian Academy of Sciences, explained RIA News, which is why there is no collective immunity to COVID-19 in Russia. According to her, this situation has developed due to the low rates of vaccination and the variability of the virus.
“We all hoped for him very much. We thought there would be vaccination and immunity. But the rate of vaccination in Russia is low. In addition, the delta strain began to spread, reducing the effectiveness of the vaccine. It turns out that those who have already been ill and vaccinated should be revaccinated, and the rate of revaccination is even worse than that of vaccination. The process stretched out in time, the collective immunity did not have time to form, and when it happens depends on our behavior and on further mutations of the virus, ”said the biologist.
In addition, she did not rule out the possibility of a “delta last” variation of the coronavirus. She believes that such a development of events makes the fight against coronavirus easier and will preserve the effectiveness of vaccines.
Earlier, experts from the National Institutes of Health in the United States recorded a long-term confirmed case of COVID-19 in a patient – a woman was ill for 355 days. As a result of the treatment, the patient was able to fully recover.
