People who have been immunized in Johnson and Johnson over recent weeks shouldn’t be anxious, federal officials said. Considering the national shooting break after six cases of a rare form of the blood clot. But keep an eye on potential warning signs.
Six cases were recorded in females between 18 and 48 who had symptoms 6 to 13 days after shooting. One is dead and another patient is in critical condition. Officials of the Food and Drug Administration and Disease Control and Prevention Centers said on Tuesday.
Both women developed a form of coagulation called cerebrae sinus thrombosis, or CVST. A blood clot in brain blood draining vessels combined with low blood platelet or FDA and CDC thrombocytopenia.
Should I worry about that?
For people who received the Johnson & Johnson vaccine over a month ago, without any signs, there’s no cause for concern. Dr. Anthony Fauci, the National Institute of Allergy and Infectious Diseases Director, said later on Tuesday in a separate White House briefing. This is because by now any serious reaction would have been obvious.
For those that have been shot over the last few weeks by Johnson & Johnson, it is critical to be alert for symptoms.
Symptoms are as follows:
- Extreme tumult.
- Abdominal Dolor
- The pain of the leg
“First of all, don’t get an anxiety response because it’s less than one out of a million,” said Fauci. “Having said that, however, pay attention.”
He said also potential symptoms are chest pain or neurological signs that may involve visual changes.
People who have recently been shot and suffer from some of the symptoms should contact their health care provider, officials said. According to the FDA and CDC officials, healthcare professionals need to know that treatment for this particular form of blood clot is distinct .
“An anticoagulant known as heparin is usually used for treating blood clots. Heparin can be harmful in this context and alternative therapies must be provided,” according to the joint declaration of the two agencies.
Treating heparin “can be an error in this case as it could be unsafe and make it worse,” said Fauci.
Symptoms of blood clot
Dr. Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, said during a meeting: “If anyone ends up with a very bad headache or some form of shortness of breath, leg pain, or severe abdominal pain, they’d like to seek medical care.
For people who received the vaccine more than a month ago, the risk is “very mild,” Schuchat said on Tuesday.
Clots seem exceedingly rare: almost seven million people have taken shots from Johnson & Johnson since the FDA granted the shots in February for emergency use.
The signs of blood clot vary from the immediate side effects within a few days of a Covid-19 shot. There are flu-like aches or headaches.
Though cases have occurred in women of childbearing age, a relationship with birth control does not appear to exist, Marks said. Blood clots from birth control medicines are usually caused by a particular hormone process. In case of the vaccine, one common principle is that the body produces anticorps that stimulate platelets.
The concerns are understood by Dr Seth Trueger, Assistant Professor of Emergency Medicine at Northwestern University.
Headache is serious and other neurological symptoms may follow it, such as double vision. This isn’t a gentle headache.
“If in the absence of a vaccine you wouldn’t be concerned about those symptoms, you’re unlikely to experience significant complications,” he said.
Dr. Ali Raja, an emergency medicine professor at the Harvard Medical School, said headache is normally worse than previous headaches in patients he has seen with CVST.
“Patients I saw with cerebral venous sinus thrombosis are not just headaches, it’s a really serious headache,” he said.
Since health officials still understand the exact cause, nothing can stop the immune reaction right now. Raja said patients who experience serious headache must immediately be examined by a doctor if they develop a severe Johnson & Johnson vaccine within three weeks.
“You don’t have to assess the mild headache, but you do have a severe headache, especially a severe headache that’s worse than any other headache that you’ve ever had,” he said.
The estimated CVST incidence alone is approximately 2 to 14 people per year, said Marks. However, since CVST in combination with low platelets is so rare, it is not known how many annual cases the conditions of the six women are encountered.
There are currently no records of the disorder associated with the Pfizer-BioNTech and Moderna mRNA vaccines. Since December, there have been over 180 million doses of mRNA vaccines given in the U.S.
“We are not seeing low platelet counting clotting incidents with the other two vaccines,” said Dr. Anne Schuchat, CDC’s Chief Supervisor, Tuesday. “People with vaccination appointments should proceed with their appointments with the other two vaccines.”
