German researchers have proposed a solution to prevent blood clots caused by two leading COVID-19 vaccines. Other scientists warn it is too early to draw conclusions about the mechanism behind the potentially deadly condition, CBC reports. The researchers behind the new preprint study say they hope their theory could eventually help laboratories adapt the AstraZeneca-Oxford and Johnson & Johnson vaccines to increase safety and boost global vaccination efforts. Though uncommon, vaccine-induced immune thrombotic thrombocytopenia (VITT) is much more severe than a typical blood clot because it can cause cerebral venous sinus thrombosis (CVST), in which veins that drain blood from the brain are obstructed and can cause fatal bleeding.
