Washington D.C. – The U.S. Centers for Disease Control and Prevention (CDC) and the U.S. Food and Drug Administration (FDA) on Tuesday issued a statement regarding the Johnson & Johnson COVID19 vaccine after pausing its use in the US.
Both the agencies are reviewing data involving six reported U.S. cases of a rare type of blood clot in individuals after receiving Johnson & Johnson COVID-19 vaccine, CDC and FDA said in a joint media briefing.
In a statement, FDA said 6.8 million doses of the J&J vaccine have been administered and the agency is investigating six reported cases of a rare and severe blood clot occurring in patients who received the vaccine.
The CDC will convene a meeting of the Advisory Committee on Immunization Practices on Wednesday to review the cases.
Johnson & Johnson in a statement said, “We are aware of an extremely rare disorder involving people with blood clots in combination with low platelets in a small number of individuals who have received our COVID-19 vaccine. The United States Centers for Disease Control (CDC) and Food and Drug Administration (FDA) are reviewing data involving six reported U.S. cases out of more than 6.8 million doses administered. Out of an abundance of caution, the CDC and FDA have recommended a pause in the use of our vaccine.”
The company said they are also reviewing these cases with European regulators and “we have made the decision to proactively delay the rollout of our vaccine in Europe.”

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 recordingExternal Link Disclaimer of that media call is available on the FDA’s YouTube channel.
