Immunologist Nikolai Kryuchkov told in an interview with Radio Sputnik, why races of the level of antibodies to coronavirus in the blood occur. According to him, after vaccination or illness, their level is maximum, but over time begins to decline.
Specialist explained that the largest concentration of antibodies is usually formed after some time after the introduction of the vaccine, or the suffering disease, after which they are recession. In the case when after this test identifies the next increase in the number of antibodies, one of two options is possible, the doctor emphasized.
“If a small increase in IgG or IgM antibodies occurred, then most likely it is that the measurement was carried out by different test systems to determine the number of antibodies in the blood plasma. In addition, you must not forget that each test has it Error, and there are individual fluctuations. It is all superimposed and can give an increased level of antibodies, “the doctor noted.
For a significant increase in the number of antibodies – more than twice, there is a different explanation. A serious jump in the number of antibodies, most likely, means a meeting with infection, an immunologist believes. He added that in some cases it is almost the only sign of a new contact with the virus. He explained that half of the cases of infection passes asymptomatic, in which case the body and the immune system react, and the clinical manifestations of a person do not.
Earlier, director of the National Research Center of Epidemiology and Microbiology named after N. F. Gamaley Alexander Ginzburg stated that the vaccination from Coronavirus should be included in the National Calendar vaccinations. He stated that the pandemic will end when 70-75 percent of the world’s population will be vaccinated from COVID-19.
