The recommendation came from the US Food Administration and the Centers for Disease Control and Prevention, to investigate cases of blood clots caused by the vaccine for some people, according to Sky News.
The US Food and Drug Administration confirmed via “Twitter” that it and the Centers for Disease Control and Prevention “are assessing the potential importance of 6 cases that were recorded of rare blood clots of its kind in people who received the vaccine.
She stated, “We recommend a freeze until this process is completed.”
The six reported cases were among more than 6.8 million doses of the Johnson & Johnson vaccine administered in the United States.
All six cases occurred in women between the ages of 18 and 48, and symptoms appeared 6 to 13 days after vaccination, according to a joint statement by the First Deputy Director of the CDC, Dr. Ann Schuchat, and the Director of the Center for Biological Assessment and Research at the Food and Drug Administration, Dr. Peter Marks.
