Suspending administration of the Johnson & Johnson vaccine

As of 4/13/2021:
The CDC has recommended suspending administration of the Johnson & Johnson vaccine.
As of April 12, more than 6.8 million doses of the Johnson & Johnson vaccine have been administered in the US. The CDC and FDA are reviewing data involving six reported U.S. cases of a rare and severe type of blood clot in the 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). All six cases occurred among women between the ages of 18 and 48, and symptoms occurred 6 to 13 days after vaccination. Right now, these adverse events appear to be extremely rare. COVID-19 vaccine safety is a top priority for the federal government, and we take all reports of health problems following COVID-19 vaccination very seriously. People who have received the J&J vaccine who develop severe headache, abdominal pain, leg pain, or shortness of breath within three weeks after vaccination should contact their health care provider.
