As of April 12, more than 6.8 million doses of the Johnson & Johnson vaccine have been administered in the U.S. The CDC and FDA 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. A type of blood clot was seen in combination with low levels of platelets. All six cases occurred among women between the ages of 18 and 48 from 6 - 13 days after vaccination. CDC will convene a meeting on Wednesday to further review these cases and assess their potential significance. At this time, an immediate pause is being recommended. | PRESS RELEASE
