A precedent-setting study on natural immunity was published in Cell on July 14, 2021. The study finds that natural immunity to SARS-CoV-2, the virus responsible for COVID-19, is comprehensive and durable, with persisting antibody responses, robust memory B cell recognition and T cell immunity. The study followed 254 covid patients for eight months and measured immune markers in their blood samples. The recovered patients included men and women who experienced a range of outcomes, from mild, moderate, and severe disease.
The researchers used cross-sectional and longitudinal studies and found that SARS-CoV-2 infection causes the immune system to generate poly-clonal, humoral and cellular immune responses that target multiple viral proteins while establishing long-term immunity to SARS-CoV-2 and a host of other coronaviruses.
