Abstract

The measure of torquetenovirus (TTV) viremia is widely recognized as an optimal biomarker of an individual immune status. In the context of COVID-19, the predictive role of TTV load with regard to vaccine response has also been demonstrated, suggesting other intriguing applications for this widespread anellovirus.

Keywords: COVID-19; TTV; immune response; torquetenovirus; vaccine.
