blood clot concerns with vaccine

please upgrade to the latest version for the best experience. what still has some people worried is the possibility of blood clots developing – a condition called thrombosis with thrombocytopenia syndrome (tts) – with the one-shot johnson & johnson (janssen) vaccine. however, the cdc and fda did advise women younger than 50 to be aware of the risk, noting that it had not been seen in the pfizer and moderna vaccines. though, one study determined that people were eight to 10 times more likely to develop blood clots in the brain from having covid itself rather than from receiving either of the pfizer or moderna vaccines. in the meantime, dr. asif wahid, a cardiologist at novant health cardiology in thomasville and lexington, answered some of the most pressing questions. blood clots are blood-formed blockages in the vein that can affect circulation. if left untreated, the clot can break free and travel to the lungs.




a long drive or long flight can also put you at risk for blood clots. some covid patients have developed blood clots in multiple places throughout the body, and patients that have diabetes or high blood pressure are at a higher risk. tts is a rare condition in which blood clots are accompanied by a low level of platelets, the colorless blood cells that help blood to clot. however, if platelets drop below normal levels, patients are at increased risk of cerebral venous sinus thrombosis (cvst), a blood clot in the brain that can be life-threatening. similar occurrences of tts were observed following the rollout of the astrazeneca covid-19 vaccine in europe. while blood clots are normally treated with a blood thinner medication, patients that develop tts as a result of the vaccine may require a different treatment regimen. before coming to market, each vaccine had to go through a strict approval process, and the cdc and fda continue to monitor for possible side effects.

despite overwhelming evidence that the benefits of the covid-19 vaccine outweigh the risks, and that the chances of dying from the coronavirus far exceed those of having an adverse reaction to the shot, reports of rare, (fewer than one in a million) post-vaccine blood clots may have you reconsidering vaccination. although it is hard to quantify exactly how many people in the united states experience such blood clots, as many as 900,000–1 to 2 per 1,000–could be affected annually, dr. desancho says. “the risk of getting a blood clot either venous or arterial from the covid-19 vaccines is very minimal compared to the risk in the general population,” she says. out of 34 million recipients of the astrazeneca-oxford vaccine, there were only 169 possible cases of blood clots in the brain, and 53 possible cases of abdominal blood clots; whereas, among the more than 7 million recipients of the johnson & johnson/janssen vaccine, there were just six possible cases of blood clots in the brain, she explains. a blood clot is a gel-like clump of blood that forms to stop the bleeding of an injured artery or vein.

(both the johnson & johnson/ janssen and astrazeneca-oxford vaccines are believed to have triggered the production of antibodies that activated the production of platelets, which then caused blood clotting and abnormal bleeding.) even covid can trigger a blood clot. they can also travel (embolism) through your bloodstream to various parts of the body and cause a range of health problems, depending on their size and location. other risk factors may include: symptoms of blood clots depend on where they’re located. in the brain, a blood clot may cause loss of speech or vision, extreme dizziness, or weakness along one side of the body. because such symptoms may indicate other health problems, your doctor may conduct various diagnostic procedures, including blood tests, ultrasound, a ct scan, magnetic resonance angiography (mra) (which looks specifically at blood vessels), or a v/q scan, (which tests the flow of air and blood in the lungs), to rule out other conditions.

as mentioned above, the clotting condition associated with the j&j vaccine is called thrombosis with thrombocytopenia (tts). thrombosis occurs the clots that have been tentatively linked to the astrazeneca and j&j vaccines have particular characteristics: they occur in unusual parts of what kind of blood clot has been associated with the j&j vaccine? tts is a rare condition in which blood clots are accompanied by a low level of, .

the fda said the decision was made after more information was shared about the occurrence of a rare blood clotting condition, thrombosis with thrombocytopenia syndrome (tts), 1 or 2 weeks after people received the j&j vaccine. the finding u201cwarrants limiting the authorized use of the vaccine,u201d the fda said. yet, dr. desancho stresses that your risk of developing a vaccine-related blood clot is no greater than the general population’s overall blood covid-19 vaccine astrazeneca is not associated with an increased overall risk of blood clotting disorders. there have been very rare cases of with the johnson & johnson vaccine, the cdc reports seeing thrombosis with thrombocytopenia syndrome at a rate of about seven cases per 1, .
