U.S. health regulators suspended the vaccine and investigated six reports of blood clots in women aged 18 to 48
new York- On Tuesday morning, the US federal health regulator recommended that Johnson & Johnson’s Covid-19 vaccine be suspended, and six reports of blood clots in women aged 18 to 48 were investigated. One died and the other was hospitalized in critical condition.
As of Monday, 6.8 million people in the United States have been vaccinated with the vaccine, and no other serious adverse reactions have been reported.
Experts have not yet determined to what extent the vaccine caused blood clots. However, the investigation follows the actions of European regulatory agencies, which concluded that the vaccine produced by AstraZeneca may also be the cause of a similar and extremely rare bleeding disease.
Public health experts from the United States and Europe emphasized that for most people, the benefits of the Covid vaccine far outweigh the risks.
Last week, several European countries restricted the use of AstraZeneca and Oxford vaccines to the elderly because blood disorders rarely occur among young people. The AstraZeneca vaccine has not yet been licensed in the United States.
What does this mean for people who have recently received the Johnson & Johnson vaccine?
Currently, less than one in a million of Johnson & Johnson vaccines under study. If there is a real risk of blood clots due to the vaccine (not yet determined), the risk is extremely low. The risk of signing Covid-19 in the United States is much higher.
What is a pause?
During clinical trials and after the vaccine is widely used, experts will follow up on the medical issues of the vaccine recipients. In the event of an abnormal situation, the regulatory agency may decide to suspend the trial or stop using the vaccine for further investigation.
What caused the suspension?
In the United States, six women who received the Johnson & Johnson vaccine developed a rare disease involving blood clots within two weeks of being vaccinated. In this case, called cerebral venous sinus thrombosis, a clot is formed in the blood and the blood is expelled from the brain. CDC’s Dr. Anne Schuchat said the result was “similar to a stroke.”
What is a blood clot?
A blood clot is a thick gel-like blood spot that can block the circulation. A clot is a response to injury and can also be caused by many diseases, such as cancer and genetic diseases, certain medications, and sitting or lying in bed for long periods of time. Covid itself can cause serious clotting problems. Blood clots that form in the legs sometimes spread out and flow to the lungs, and rarely even enter the brain, where they can be fatal.
How common are blood clots?
According to data from the Centers for Disease Control and Prevention, 300,000 to 600,000 people in the United States form blood clots each year in veins in the lungs or legs or other parts of the body.
According to these data, in the U.S. population where millions of people are vaccinated every day, 1,000 to 2,000 blood clots occur every day. .
How does Johnson & Johnson comment on the new case?
On Tuesday, Johnson & Johnson stated that the company is aware of a very small number of rare diseases involving patients with blood clots and low platelets among the few people receiving the Covid vaccine. The company said in a statement: “In addition, we have been reviewing these cases with European health authorities.” “We have decided to proactively postpone the launch of our vaccine in Europe.”
Is this related to the European AstraZeneca vaccine?
At a press conference on Tuesday, Dr. Marks of the FDA said that these cases are “very, very similar.”
Johnson & Johnson and AstraZeneca both use adenovirus to transfer DNA into human cells, thereby starting to enhance immunity to the coronavirus. It is not clear whether this technology will cause problems.
What are the symptoms of bleeding disorders related to AstraZeneca vaccine?
European regulatory agencies recommend that vaccinators should seek medical help for a variety of possible symptoms, including swelling of the legs, persistent abdominal pain, severe and persistent headaches or blurred vision, and small blood spots under the skin. Given.
Can this disease be treated?
Doctors in Germany and Norway have used blood thinners and intravenous immunoglobulin to treat blood thinners to stop the growth of blood clots, which can help clear the wrong antibodies that are causing the problem.
Does this risk mainly affect women?
We don’t know yet. The six cases under investigation in the population receiving Johnson & Johnson vaccination involve women. However, this number is so small that no clear conclusion can be drawn from it.
Are rare blood clots related to Moderna and Pfizer-BioNTech vaccines?
The FDA has not found similar cases in people using Moderna or Pfizer-BioNTech vaccines.
However, a small number of patients receiving Moderna, Pfizer-BioNTech and AstraZeneca vaccines have reported low platelet levels. One recipient, a Florida doctor, died of cerebral hemorrhage due to poor recovery of platelet levels. The others were hospitalized. US health officials said that these cases are being investigated, but the results of these reviews have not been reported, and no link to the vaccine has been indicated.
