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 risk factors and improving future vaccine development. . .
