And more types of antibodies were producedScientists from Stanford University in the USA conducted a study in which clinical trials of the Pfizer coronavirus vaccine were conducted.Discuss It turned out. that in those people who were vaccinated, the level of antibodies was higher, as well as the set of types of antibodies to the virus. Those who were not vaccinated and had been ill did not have such an immune response.
It is noted that the study was conducted with the participation of patients who were treated in the first months of the pandemic, most likely from early variants of the coronavirus. Antibodies were produced both after infection and after vaccination, but decreased in both cases. But the infected patients had fewer antibodies.
At the same time, the vaccinated produced antibodies that were targeted at the spike-shaped S-protein characteristic of the classic coronavirus strain. But they could also bind to proteins from 9 other strains, including Delta proteins. These patients also had fewer antibodies capable of binding to the S-protein.
