Warning Signs You Have a COVID Vaccine Blood Clot, Says Dr. Fauci

Blood clots “less than one in a million” after the J&J vaccine. These are the symptoms.

Both the Centers for Disease Control and Prevention and the U.S. Food and Drug Administration have agreed that the Johnson & Johnson vaccine may provoke cerebral venous sinus thrombosis—a rare blood clotting condition that can be deadly. According to a statement released on Tuesday there have been a total of six cases (out of nearly 7 million), occurring among women between the ages of 18 and 48, with symptoms arising 6 to 13 days after vaccination. Later in the day, Dr. Anthony Fauci, the chief medical advisor to the President and the director of the National Institute of Allergy and Infectious Diseases also addressed the issue, revealing there are a few symptoms to look out for. Read on to find out what they are—and to ensure your health and the health of others, don't miss these Signs Your Illness is Actually Coronavirus in Disguise.


You Might Have a Headache

The first symptom Dr. Fauci mentioned to look out for is a headache. "The manifestations of this are that headache is the very common component of it because the sinus thrombosis that they have is the draining of the blood in the brain. And it will cause enough symptomatology to make you notice it." According to the Michigan Comprehensive Stroke Center the most common symptom of Sinus Vein Thrombosis is a really severe headache, "often the worst headache that a patient has ever had," they describe. "It can be of sudden onset, develop over a few hours, or develop over a few days."

Dr. Fauci did note that if you did get the shot, try not to stress out just yet. "It's less than one in a million," he said about the chances of developing the condition. "However, having said that, pay attention." In general, the best thing to do is to "just watch out for not feeling very well," says Dr. Fauci.
