Study Shows Initial SARS-CoV-2 Vaccinations Prepares Immune Cells for Response to Subsequent Variants
India, March 18 -- Antibody responses to new SARS-CoV-2 variant infections and vaccinations are powerfully shaped by prior exposures to earlier SARS-CoV-2 vaccines, according to a new study from the Perelman School of Medicine at the University of Pennsylvania.
In the study, published today in Immunity, the researchers analyzed antibody responses in people infected with or vaccinated against the relatively new SARS-CoV-2 variants BA.5 and XBB. They found that even though BA.5 and XBB are very different from the original "ancestral" version of SARS-CoV-2, the responses to these newer variants came almost entirely from the B cell repertoire that was already in place due to prior vaccinations against the ancestral strain.
The good news is ...
