Immune Response in COVID-19 Recovered Vaccinated and Unvaccinated Individuals Related to Post-COVID-Syndrome

G. C, K. M, et al.

This study by Gerhards et al. explores the fascinating dynamics of antibodies in COVID-19 recovered individuals over 12 months, revealing intriguing insights into the impact of vaccination and the prevalence of Post-COVID Syndrome. Discover the significant trends in antibody levels and cognitive symptoms that arise a year after recovery.

Abstract
This study investigated the 12-month antibody dynamics in COVID-19 recovered individuals, focusing on the receptor-binding domain (RBD) of the spike (S) protein and nucleocapsid (N) protein. The study also aimed to identify clinical parameters correlated with declining antibody levels and to evaluate the prevalence and symptoms of Post-COVID Syndrome (PCS) after one year. Results showed stable anti-RBD/S1 antibody levels in unvaccinated individuals, a significant booster effect of vaccination, and a significant decrease in anti-N antibodies. A prediction model for antibody decline was developed using a random forest algorithm. PCS prevalence was 38.6% at 12 months, with an increase in cognitive impairments. Cell-free DNA (cfDNA) did not effectively differentiate between subjects with and without PCS.
