For those who have been vaccinated against the CORONAVIRUS, but become infected, the post-covid syndrome will be easier, the DIRECTOR of the National Research Center for Epidemiology and Microbiology named after V.I. N. F. Gamalei Alexander Gintsburg.
“[In the case of vaccination] the entire disease process occurs at the level of the nasopharynx, and the post-COVID syndrome occurs when the pathogen descends into the lungs or spreads throughout the body,” Gunzburg explained.
Immunologist Vladimir Bolibok, speaking about the likelihood of getting covid-19 again , in a conversation with RBC noted that infection a second time with any antibody titer is unlikely. However, if the titer is high, then the disease will be milder or asymptomatic. “The higher the antibody titer, the less likely a person is to get infected and get sick. But the basis of antiviral immunity is cellular immunity, which we do not test for. The presence of antibodies indicates that the human immune system is familiar with this pathogen, but if he has weakened cellular immunity, he can still get sick, ”Bolibok explained.
According to him, people with cancer or autoimmune diseases who take immunosuppressive drugs are more likely to get sick again.
Immunologist, HEAD of the Laboratory of Vaccine Prevention and Immunotherapy of Allergic Diseases, Research Institute of Vaccines and Serums named after V.I. I.I. Mechnikov of the Russian Academy of Medical Sciences, Mikhail Kostinov, in turn, said that in people with defects in the immune system, antibodies can be produced, but not work.
