Wednesday, January 6, 2021 COVID-19 Immunity Appears to Last 6 to 8 Months, Study Suggests Scanning electron micrograph of a cell infected with SARS-CoV-2 particles. Credit: NIAID Most people who recover from COVID-19 develop immune memory that lasts for at least six to eight months, a NIAID-funded study suggests. The findings, published today in Science, are based on analysis of blood samples from 188 people who recovered from infection with SARS-CoV-2, the virus that causes COVID-19. While immune responses varied over time and among different individuals, most people developed antibodies, memory B cells, and memory T cells against SARS-CoV-2 and retained robust immune memory approximately six months after infection. Advancing understanding of immune memory to SARS-CoV-2 is critical for improving diagnostics and vaccines and for assessing the future course of the COVID-19 pandemic.
