By FLINDERS UNIVERSITY MAY 26, 2024 Researchers from Flinders University, along with international experts, have discovered that the PF4 antibodies causing VITT after adenovirus vector-based COVID-19 vaccination share identical molecular signatures with those found in similar cases following natural adenovirus infection. This finding, using a new approach developed at Flinders, has significant implications for understanding the genetic […]

People with long COVID have distinct patterns of inflammation detectable in the blood, which could potentially be targeted with immune therapies.

Findings from the largest UK study of patients hospitalized with SARS-CoV-2 infection show that long COVID leads to ongoing inflammation which can be detected in the blood. In an analysis of more than 650 people who had been hospitalized with severe COVID-19, patients with prolonged symptoms showed evidence of immune system activation. The exact pattern […]
