Study Finds Greater Antibody Response in Recovered COVID-19 Patients Than Vaccinated Ones
A new study has found that individuals that have previously contracted COVID-19 show a more potent antibody response than those who were solely vaccinated for the respiratory virus.
Conducted by a research team at Rockefeller University in New York, the analysis found “that between a first (prime) and second (booster) shot of either the Pfizer-BioNTech or Moderna vaccine, the memory B cells of infection-naïve individuals produced antibodies that evolved increased neutralizing activity against SARS-CoV-2,” but also that “no additional increase in the potency or breadth of this activity was observed thereafter.”
Meanwhile, researchers determined that not only do recovered COVID-19 patients possess neutralizing antibodies up to a year after infection, but that such infection simultaneously assists in offering protection against developing variants.
“Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection produces B-cell responses that continue to evolve for at least one year,” the study read. “During that time, memory B cells express increasingly broad and potent antibodies that are resistant to mutations found in variants of concern.” (Read more from “Study Finds Greater Antibody Response in Recovered COVID-19 Patients Than Vaccinated Ones” HERE)
