C.D.C. Is Investigating a Heart Problem in a Few Young Vaccine Recipients
Officials said the agency is reviewing several dozen reports that teenagers and young adults may have myocarditis after vaccination. But the agency has not determined whether the vaccine has caused the condition.
According to the agency's Vaccine Safety Group, the Center for Disease Control and Prevention is looking into reports that a very small number of teenagers and young adults have been vaccinated with the corona virus, which can cause heart problems.
The group's statement was sparse in details, stating only that there were "relatively few" cases and that they may be completely unrelated to vaccination. The condition, called myocarditis, is an inflammation of the heart muscle, and can occur after some infections.
The CDC's review of the report is at an early stage, and the agency has not yet determined whether there is any evidence that the vaccines caused the heart condition. It posted some guidance on its website for doctors and physicians to be alert to abnormal heart symptoms in young people who had just received their shots.
"It can only be a coincidence that some people are developing myocarditis after vaccination," said Dr. Celine Gounder, an infectious disease specialist at Bellevue Hospital Center in New York. "Something like this is more likely to happen by chance, because a lot of people have been vaccinated right now."
The cases appear to have occurred mainly in adolescents and young adults four days after the second dose of one of the mRNA vaccines, which are modern and Pfizer-Bionotek. Or cases were more common in men than women.
The vaccine safety group said, "Most of the cases seem mild, and the cases keep coming up." The CDC strongly recommends Kovid vaccines for Americans 12 and older.
"We are eager to see more data about these cases, so we can better understand whether they are related to vaccines or if they are coincidental," said Dr., president of the American Academy of Pediatrics Committee on Infectious Diseases. he said. Yvonne Maldonado said. "Meanwhile, it is important for pediatricians and other physicians to report any health concerns that may arise after vaccination."
Experts emphasize that the potentially rare side effects of myocarditis are minimized compared to the potential risks of Kovid 19, including persistent syndrome called "long Kovid 19". Only acute covid19 can cause myocarditis.
As of May 13, coronoviruses have infected more than 3.9 million children and sent more than 16,000 to hospitals, more than hospitalized for the flu in an average year, according to data collected by A.A.P. accordingly. Accordingly. Approximately 300 children have died of Covid-19 in the United States, making it one of the top 10 causes of death in children since the epidemic began.
"Or is it in the context of all mitigation measures," an emergency medical doctor at Brigham and Women's Hospital in Boston, Drs. he said. Said Jeremy Faust.
Coronavirus outbreak
- The sale of private vaccines in Pakistan exposes the rich-poor division of the world.
- As soon as an outbreak of the virus occurs in Nepal, its parliament is dissolved.
- The CDC is investigating heart problems in some young vaccine recipients.
In the general population, about 10 to 20 out of every 100,000 people develop myocarditis and heart inflammation every year, which experience symptoms ranging from fatigue or chest pain to arrhythmia and cardiac arrest. According to the researchers, many others are likely to have mild symptoms and are never diagnosed.
At the moment, the number of reported cases of myocarditis after vaccination is not higher than in young people, C.D.C. But members of the agency's vaccine safety group "felt that information about reports of myocarditis should be given to providers," the report said.
The agency did not specify the age of the patients involved. The Pfizer-BioNtech vaccine has been authorized for 16 years and older since December. Earlier this month, the Food and Drug Administration extended that right to children between 12 and 15 years of age.
On 14 May, the C.D.C. Aware of physicians for a possible link between myocarditis and vaccines. Or on May 17, the working group reviewed reports filed with the Department of Defense data on myocarditis, the Vaccine Adverse Event Reporting System and others.
State health departments in Washington, Oregon and California have alerted emergency providers and cardiologists to a potential problem, or submitted a report of seven cases to the journal Pediatrics for review.
Dr. Liam Yor, former president of the Washington State Chapter of the American College of Emergency Physicians, said in an interview that he had recently seen a teenager suffering from myocarditis after vaccination.
The patient was treated for mild swelling of the lining of the heart, or was later sent home. But the teenager later returned to care with a decrease in cardiac output. Nevertheless, Dr. Your said that he had seen worse outcomes with Kovid in puberty, including a 9-year-old child who had arrived at the hospital after a cardiac arrest last winter.
"The relative risk in favor of receiving the vaccine is very high, especially given how many doses of the vaccine are given," he said.
More than 161 million people in the United States have received at least one dose of the coronavirus vaccine; About 4.5 million of them were aged between 12 and 18 years.
