(TNS) On Tuesday, the Centers for Disease Control and Prevention along with the United States Food and Drug Administration called for federal vaccination sites to pause the use of Johnson & Johnson doses.

While the action was meant for federal sites, the agencies recommended states follow suit after six women developed a very rare blood clot disorder, according to the CDC.

So far, the United States has administered more than 6.8 million doses of the Johnson & Johnson vaccine. About another 9 million doses have been distributed to states.

The FDA and CDC said the move came out of an abundance of caution. The agencies plan to share more during a scheduled 10 a.m. briefing on YouTube.

Here is the full joint statement from the two federal health agencies.

“As of April 12, more than 6.8 million doses of the Johnson & Johnson (Janssen) vaccine have been administered in the U.S. 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. 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. Treatment of this specific type of blood clot is different from the treatment that might typically be administered. Usually, an anticoagulant drug called heparin is used to treat blood clots. In this setting, administration of heparin may be dangerous, and alternative treatments need to be given.

CDC will convene a meeting of the Advisory Committee on Immunization Practices (ACIP) on Wednesday to further review these cases and assess their potential significance. FDA will review that analysis as it also investigates these cases. Until that process is complete, we are recommending a pause in the use of this vaccine out of an abundance of caution. This is important, in part, to ensure that the health care provider community is aware of the potential for these adverse events and can plan for proper recognition and management due to the unique treatment required with this type of blood clot.

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. Health care providers are asked to report adverse events to the Vaccine Adverse Event Reporting System at https://vaers.hhs.gov/reportevent.html.

CDC and FDA will provide additional information and answer questions later today at a media briefing. A recording of that media call will be available on the FDA’s YouTube channel.”
