The unusual side effect to both vaccines seemed to be striking only people under age 50, most of whom were women.
Vaccine experts doubt that the committee would recommend shelving the vaccine altogether, because the side effect is so rare.
CDC head Rochelle Walensky said Monday that while the agency has received more reports of medical conditions, it was still investigating whether they were connected to the shots, and was not hearing about a substantial number of new cases.
The agency paused use of the vaccine to draw attention to the problem, hoping to learn of more cases if there were any and also to warn doctors not to treat these patients with the drug usually used for blood clots, heparin, which can worsen these symptoms.
Many public health experts this week seemed convinced that the government had done the right thing by pausing the vaccine, though all felt it should now be allowed back into use.
"I want this vaccine back as soon as possible," said Dr. Amesh Adalja, an infectious disease expert and senior scholar with the Johns Hopkins University Center for Health Security. "I was recommending it preferentially to my friends. One and done."
Adalja, also a fellow with the Infectious Diseases Society of America, said on a Thursday IDSA call with the media that he hasn't been a fan of the pause. He worried people would lose faith in the vaccine and that there were other ways to draw attention to safety concerns.
Others think the CDC and FDA made the right decision to pause vaccination, though they are eager to see it back in use.
