A brand new examine examined the upkeep of reminiscence B cell responses to SARS-CoV-2, the virus that causes COVID-19, after restoration from pure an infection or post-vaccination. The examine is revealed within the peer-reviewed journal Viral Immunology.

The examine, coauthored by David Fear, from King’s College London, and colleagues, confirmed that amongst these recovered from pure an infection, COVID-19 serologically-positive donors had robust antigen-specific reminiscence B cell-associated responses. Post-vaccination, donors confirmed sturdy serological antigen-specific antibody responses in opposition to spike protein that waned over time. Memory B cell-associated responses in opposition to spike protein had been additionally noticed however confirmed much less waning over time.

“This study is of particular relevance at the moment, because with millions vaccinated, previously infected, or both, studies such as this one may tell us how long we might expect the immunity to last,” says Rodney S. Russell, PhD, Editor-in-Chief of Viral Immunology, from Memorial University of Newfoundland, St. John’s.
