The ladies developed the situation inside about two weeks of receiving the shot, U.S. well being officers informed reporters on Tuesday.
The assembly is scheduled to run from 1:30 to 4:30 p.m. ET.
On Tuesday, the Meals and Drug Administration requested states to briefly halt utilizing J&J’s vaccine “out of an abundance of warning” following the experiences of blood clots. Shortly after the FDA issued the warning, greater than a dozen states, in addition to some pharmacies, took steps to halt inoculations with J&J’s vaccine, some changing scheduled appointments with both the Pfizer or Moderna vaccine.
White Home chief medical advisor Dr. Anthony Fauci mentioned Tuesday that the beneficial pause on using the vaccine will give U.S. well being regulators the time they should completely examine the circumstances. Fauci mentioned officers on the FDA and the CDC need to see if there are “any clues” and “discover some widespread denominators among the many girls who had been concerned” that could possibly be enabling the blood clotting dysfunction.
“We’re completely conscious that this can be a uncommon occasion. We need to get this labored out as rapidly as we presumably can and that is why you see the phrase ‘pause,’ in different phrases, you need to maintain off for a bit,” Fauci mentioned. “We need to go away that as much as the FDA and the CDC to analyze this fastidiously. I do not suppose it was pulling the set off too rapidly.”
Out of the roughly 120 million individuals within the U.S. who’ve obtained no less than one vaccine dose, roughly 6.9 million have obtained J&J’s vaccine, Fauci mentioned, noting that there have not been any “pink flag alerts” from the Pfizer or Moderna Covid-19 vaccines that depend on mRNA expertise of their photographs.

“We all know that for these vaccines, that for the primary a number of days after vaccination, there are flu-like signs that may embrace headache,” he mentioned, including that these are possible widespread unwanted side effects. “If somebody offered to an emergency room with very extreme headache or blood clots,” docs ought to ask whether or not they just lately obtained a vaccine earlier than placing collectively a plan of care. If the affected person additionally has low platelets, docs ought to think about that it might be associated to the vaccine, he mentioned.
Marks informed reporters that researchers have not but discovered a selected trigger for the blood clotting in J&J vaccine recipients, however they believed it was just like different adeno viral vector vaccines. “That’s an immune response that happens very, very hardly ever after some individuals obtain the vaccine and that immune response results in activation of the platelets and the extraordinarily uncommon blood clots,” he mentioned.
