Doctors say they are homing in on the cause of blood clots that may be linked with certain coronavirus vaccines, and add their findings have important implications for how to treat the condition, regardless of whether vaccines cause it.
Even though the link is not yet firm, they’re calling the condition vaccine-induced immune thrombotic thrombocytopenia or VITT. It’s characterized by unusual blood clotting combined with a low number of blood-clotting cells called platelets. Patients suffer from dangerous clots and, sometimes, hemorrhaging at the same time.
It’s been linked most firmly with the AstraZeneca coronavirus vaccine, which is in wide use in Europe and the UK.
