Study shines light on longevity of immune response to COVID-19

New Delhi, May 21 (ANI): By pooling studies from eight cohorts across the United States, a group of researchers accelerated the collection of essential data to answer questions about the immune response needed for long-term protection against SARSCoV2. A description of the cohort, assays used, and event definitions were recently published in the American Society for Microbiology's open-access journal, sphere. Longitudinal observation studies (studies that employ continuous or repeated measures to follow particular individuals over time) are essential to answer important questions on the durability and effectiveness of immune responses against SARS-CoV-2. Often individual cohorts have limited longitudinal data or participant numbers to draw robust conclusions. To overcome these limitations, harmonized yet independent cohorts were established in different geographic locations of the U.S. - the PARIS (Protection Associated with Rapid Immunity to SARS-CoV-2) and SPARTA (SARS Sero Prevalence and Respiratory Tract Assessment) cohorts. These cohorts offer a nimble and rapid approach to stand up a network suitable to collect biospecimens and other data.
