(CNN) Doctors say they are homing in on the cause of blood clots that may be linked with certain coronavirus vaccines, and said their findings have important implications for how to treat the condition, regardless of whether vaccines cause it. While blood clots in the brain have received the most attention, patients have also had clots in other large veins and arteries. These blood clots in the brain -- called cerebral venous sinus thromboses or CVST -- are dramatic on their own, but the clots may be forming elsewhere, also. "While current information links VITT to AstraZeneca and Johnson & Johnson vaccines, patients with suggestive timing and symptoms following any COVID-19 vaccine should be evaluated for VITT." CDC wants to know if there is anything specific that might put people at higher risk of developing blood clots after vaccination.
