“It is possible that in the next two months there will be an increase in the number of infected and infected with the” Delta “variant. The reason is the presence of people who have neither been vaccinated nor have survived the virus.
This predicted before NOVA the immunologist from BAS Prof. Dr. Soren Hayrabedyan.
The “Delta” version is very contagious. It has about 1000 times higher viral load than the original virus.
China. “In the old version, this is 7 days, which shows how much faster this virus multiplies in the body.”

The immunologist pointed out that the effectiveness of the Pfizer vaccine against infection with the Delta strain drops to 70%, according to a study from Scotland.
“This shows that in people who have been vaccinated twice and have passed 2-3 weeks after the second vaccine, at least 70% do not become infected after encountering the virus,” explained Dr. Hayrabedyan. And the share of hospitalized is only about 2-3% – much smaller than that of unvaccinated.
“The virus has not yet mutated to such an extent that the immune system does not totally recognize it and it is as if you are getting it again,” said Dr. Hayrabedyan.
The “Delta” option is the most contagious. “On the other hand, South Africa’s Beta has the strongest ability to suppress the immune response.”

“In fact, the more contagious the coronavirus, the more damage it causes to the body, so you can expect a more severe course for sure,” said Dr. Hayrabedyan.
According to the immunologist, each individual coronavirus particle may have different mutations. This means that, for example, viruses that are defined as the “Delta” variant are characterized by a certain set of mutations. But in addition to this set, they may have other mutations.
It is currently thought that in a large percentage of people, the immune memory of covid after a disease or vaccination will be for years. After the previous SARS-CoV-1 coronavirus pandemic, some survivors had antibodies between 5 and 8 years later, Dr. Hayrabedyan said.
