Persistence of SARS-CoV-2 Antibodies in Vaccinated Health Care Workers Analyzed by Coronavirus Antigen Microarray

Individualized antibody reacitivty levels for SARS-CoV-2 antigens were successfully quantified and reactivity classification (Reactive non reactive) was performed based on a logistic regression model. Individuals were tested at several time points including their reactivity before the mRNA vaccination (Pfizer and Moderna), soon after first and second doses and up to 6 months after immunization This study follows a health care workers from the University of California Irvine medical center for a logitudinal evaluation of their antobody reactivity against SARS-CoV-2 antigen up to 6 months after immunization with mRNA vaccine.
