Studies Examine Longevity Of COVID-19 Immunity
Two studies suggest immunity to the SARS-CoV-2 virus may last at least a year for fully vaccinated individuals who have previously recovered from the virus.
Two studies suggest immunity to the SARS-CoV-2 virus may last at least a year for fully vaccinated individuals who have previously recovered from the virus. Published in Nature and bioRxiv, these papers note those who were vaccinated after recovering from COVID-19 are not likely to need booster shots, whereas those who were not infected but immunized will need the extra shot.
Both investigations found that cells still had memory of the novel coronavirus 12 months post-infection, enabling them to continue generating antibodies. The studies, “SARS-CoV-2 Infection Induces Long-Lived Bone Marrow Plasma Cells in Humans,” and “Vaccination Boosts Naturally Enhanced Neutralizing Breadth to SARS-CoV-2 One Year After Infection,” add to scientific understanding of vaccination response.
