Scientists at Johnson & Johnson on April 16 refuted an assertion in a major medical journal that the design of their COVID-19 vaccine, which is similar AstraZeneca’s, may explain why both have been linked to very rare brain blood clots in some vaccine recipients. The U.S. earlier this week paused distribution of the J&J vaccine to investigate six cases of a rare brain blood clot known as cerebral venous sinus thrombosis (CVST), accompanied by a low blood platelet count, in U.S. women under age 50, out of about 7 million people who got the shot. The blood clots in patients who received the J&J vaccine bear close resemblance to 169 cases in Europe reported with the AstraZeneca vaccine, out of 34 million doses administered there.
