For immediate release:
April 13, 2021
This morning, the U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) issued the statement below about recent reports of adverse reactions to the Johnson & Johnson (Janssen) COVID-19 vaccine and its recommendation to pause administration of the Johnson & Johnson vaccine.
Based on the federal government’s recommendation and out of an abundance of caution, the Maryland Department of Health directs all Maryland COVID-19 vaccine providers to pause the administration of Johnson & Johnson COVID-19 vaccines until further federal guidance is issued.
Providers should continue to maintain their supplies of Johnson & Johnson vaccines in a manner that prevents wastage.
The FDA and CDC statement about the Johnson & Johnson vaccine (with emphasis added):
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
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.
The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices. The agency also is responsible for the safety and security of our nation’s food supply, cosmetics, dietary supplements, products that give off electronic radiation, and for regulating tobacco products.
The Maryland Department of Health will provide more information on this situation when it becomes available.
