Leading scientists in South Africa, the country, have established some form of collective or collective immunity opposed to COVID-19 after the number of infections declined rapidly after a primary outbreak in June and July.
Commenting on a series of studies showing the highest infection rates in Western Cape and Gauteng provinces, the country’s leading vacunologist, Professor Shabir Mahdi, told Sky News that he believed the coronavirus had increased immunity levels by approximately 12 to 15 years, millions of people.
“What happened today in South Africa, the only way to do it, the only credible way to do it is that some kind of collective immunity has been achieved when combined with the use of non-pharmaceutical Array interventions. . . such as dresses with masks, physical distance, offering ventilation inside, etc. “
At the height of the pandemic, South Africa finished fifth among the world’s hardest-hit countries, the United States, India, Brazil and Russia, all of which have much larger populations.
It was at this time that researchers based in Cape Town began searching for lines of the virus in blood samples provided at local clinics through pregnant women and HIV-positive patients.
Virologists such as Dr. Marvin Hsiao were surprised to learn that an average of 40% of respondents had developed antibodies to coronavirus, and most were not known that they had been infected.
Preliminary indications of a similar study in Gauteng, which is the country’s largest city, Johannesburg, reveal that about a third of those examined had been infected.
“Inexplicably, the number (of other people inflamed with COVID-19) began to decline in late July, and at that point I could not know why,” Dr. Hsiao said.
“But when we analyzed the data, it became clear that this immunity within the (related to) population strong infection buildup is the main explanation for why we have noticed a decrease in the number of infected. “
The agreement reached through South African scientists to achieve a point of herd immunity in their country turns out to contradict a study by researchers from Imperial College London, which found that the number of other people with COVID-19 antibodies in the UK fell 6%. of the population in June to 4. 4% in September.
His “React-2” test suggests that COVID-19 immunity may be short-lived, however, Professor Mahdi questions the importance of antibody testing, noting that it evaluates the only component of the human body’s immune system.
“This decrease in antibodies does not indicate what to expect without proper examination of other parts of the immune system. Experience with SARS colds and coronavirus shows that T-cell immunity is likely to last between 2 and 3 years. “
South African researchers that the strict blockade of point five in South Africa, which was imposed in March, inadvertently worked to cause a major wave of infection.
In densely populated municipalities surrounding primary cities, citizens have been forced to ask for essentials such as food and social security payments, creating what Dr. Hsiao described as “new networks for the spread of the disease. “Social distance was virtually more unlikely on plots. where 20 or more people are forced to live nearby.
Dr Mahdi says the fact that the lock does not eliminate COVID-19 has provided the country with the accidental benefits of transitority vaccination, or more sustainable, for many South Africans.
“This inadequacy in terms of lock compliance, where we had inadvertent transmission, resulted in the immunity of a higher percentage of densely populated areas.
“There may be a question in terms of the duration of immunityArray . . . based on our delight with other coronaviruses, a benign infection (will generate immunity) for two or 3 years, but this puts us in a very smart position. “
For scientists, and policymakers, there are many paintings to be done and additional studies will be conducted in the coming weeks to better perceive the number of other people inflamed and how the virus has spread.
But the vaccination teacher obviously believes that the progression of some immunity in the population opposed to COVID-19 is not only inevitable, but a mandatory progression in the South African context.
“There is no denying that COVID is the ultimate cause of death this year, replacing HIV, tuberculosis and everything else, but the response will have to be much more nuanced than simply believing that a very restrictive blockage will eliminate the virus.
“Under no circumstances will a bachelor block the virus. “
