Official title
Serology Testing (Antibody Levels) With Time Following SARS-CoV-2 (Covid-19) Vaccinations in Residents of Nursing, Extended Care, and Over-55 Communities
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Limited information is available regarding the effects of various factors that may influence the duration and effectiveness of severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) vaccinations. This virus causes Covid-19. Such factors include age, disease states, general immunocompetence, and use of various drugs. The results of this study by Southlake Diagnostics Inc. will provide base-line antibody (IgG and total) data regarding the extent to which the results from this test can be interpreted as an indication or degree of protection from infection after vaccination with one of the three authorized SARS-CoV-2 vaccines (Pfizer, Moderna or J\& J), with information regarding various confounding factors. The study will include 30,000 male and female or more residents associated with over 300 nursing homes, extended care facilities and over-55 communities as well as staff associated with these facilities. Demographic data of the subjects including characteristics, and medical histories including concomitant medications and disease states/conditions will be collected and submitted to Southlake Diagnostics for analysis via the REDCap platform (described below). Various possible statistical correlations will be assessed.
