People who are affected by COVID and then vaccinated or vice versa have higher levels of antibodies.
According to American studythis combination provides increased immunity, which is ten times more powerful than just vaccination.
Researchers at the University of Oregon School of Medicine and Health Sciences (OHSU) in Portland, who published the study in the journal Immunology, stressed that this finding does not mean we should be deliberately exposed to the coronavirus but believes that any new infection plus vaccination will gradually mark the end of the pandemic.
The study looked at 104 people who had been fully vaccinated with Pfizer-BioNTech or Moderna, of whom 42 had never been infected with the coronavirus, 31 had been infected before vaccination and 31 after vaccination.
Blood samples of the volunteers were exposed to three different variants of the coronavirus. According to the study, people with “hybrid” immunity due to vaccination and infection had higher levels of antibodies than those who were just vaccinated.
