A rare but serious clotting disorder linked to certain COVID-19 vaccines and natural adenovirus infections has puzzled scientists for years.

Researchers have identified the molecular mechanism behind vaccine-induced immune thrombotic thrombocytopenia, or VITT, a rare clotting disorder that emerged in a small number of people who received ...

Scientists found a vaccine link to rare clotting disorder vaccine-induced immune thrombocytopenia and thrombosis (VITT) ...

Scientists say they have uncovered why a small number of people developed a rare blood clotting condition after receiving ...

Rare but deadly blood clots tied to J&J and AstraZeneca's vaccines were caused by an autoimmune reaction that some people are predisposed to, researchers found.

“We showed that the complex actually induces blood-brain barrier leakage, when the proteins alone did not,” Simões-Pires says. “Disruption of the blood-brain barrier allows for blood proteins to cross ...
