The US Centers for Disease Control and Prevention (CDC) and the US Food and Drug Administration (FDA) are recommending that the United States discontinue use of the Johnson & Johnson vaccine for Covid-19, as there have been more than six reported cases in the United States. a "rare and severe" type of blood clot.

The six reported cases were among more than 6.8 million doses of the Johnson & Johnson vaccine administered in the United States. Six cases occurred between girls and women aged 18 and 48, and symptoms occurred 6 to 13 days after vaccination. The information was made known through a joint statement on Tuesday by Dr. Anne Schuchat, Deputy Chief Executive Officer of CDC and Dr. Peter Marks, director of the FDA Center for Biologics Evaluation and Research.

"The CDC will hold a meeting of the Advisory Committee on Immunization Practices (ACIP) on Wednesday to further review these cases and assess their potential relevance," the statement said. "The FDA will review the analysis as it also investigates these cases. Until that process is complete, we are recommending a pause in using this vaccine as a precaution."
