A virologist explained everything about vaccines and revealed details about the Delta variant of COVID – Diseases

“This is an option that was identified a year ago and at the end of last year was a negligible percentage in Peru, but is currently the dominant one – by more than 80%. What we know about it is that it is spreading a lot “Successfully from the original virus, which was identified in Wuhan. It surpasses even the Brazilian version.” This was stated by the virologist Prof. Radostina Alexandrova to Bulgaria ON AIR.

“To be resistant to vaccines would mean to completely overcome the immune response that was created to previous versions of the vaccines we have. This would mean that there would be an option that had consequences. Then we will not talk about an option. , and for a new strain “, the virologist added.

“It has managed to spread to more than 120 countries. When the two doses of vaccines are given and at least two weeks have passed since the second, the level of protection against serious illness is high,” she said.

The virologist also gave an example from the United States, where a large number of infected people were fully vaccinated.

“We must say that protection against infection is generally lower, not 100%. This is the role of vaccines. “What is happening in the UK, where this option is widespread, has not ultimately been followed by a drastic increase in hospital cases,” she explained.

According to Prof. Alexandrova, the scenario in one country, where a large part of the population from the risk groups is vaccinated, is different from that in other countries.

“In Massachusetts, they found that the viral level in the upper respiratory tract in vaccinated and unvaccinated is approximately the same. This caused some of the measures to be returned there. At the same time, this is a topic that is being studied,” the virologist told Bulgaria ON AIR.

Regarding whether the Delta variant is more difficult to drive, the guest clarified that there are a number of studies that show that the risk of an infected person needing hospital treatment is twice as high.

“The Delta variant was associated with almost twice the risk of pneumonia, as well as with a higher risk of the patient needing oxygen, reaching the intensive care unit,” said Prof. Alexandrova.

The virologist also commented on the third dose of vaccines. According to her, this is not unnatural, as the purpose of the vaccine is to refresh the memory of our immune system when it encounters the virus again..
