U.S. Recommends Pausing Use Of Johnson & Johnson Vaccine Over Blood Clot Concerns
The U.S. Centers for Disease Control and Prevention and the Food and Drug Administration said Tuesday they are recommending a "pause" in the use of the single-dose Johnson & Johnson COVID-19 vaccine out of an "abundance of caution" while an investigation is conducted into reports of apparently rare, potentially dangerous blood clots.
In a joint statement on Tuesday, the two agencies said they are "reviewing data involving six reported U.S. cases of a rare and severe type of blood clot in individuals after receiving the J&J vaccine."
"In these cases, a type of blood clot called cerebral venous sinus thrombosis (CVST) was seen in combination with low levels of blood platelets (thrombocytopenia)," said Dr. Anne Schuchat, principal deputy director of the CDC and Dr. Peter Marks, director of the Food and Drug Administration's Center for Biologics Evaluation and Research. "All six cases occurred among women between the ages of 18 and 48, and symptoms occurred 6 to 13 days after vaccination."
