ការសិក្សាបានរកឃើញថា ផលវិបាកនៃបេះដូងទំនងជាមកពី Covid ជាងវ៉ាក់សាំង

Covid vaccines that use mRNA technology carry a slight risk of heart complications for some individuals, but far less than the risk of heart complications that comes with having a Covid infection, according to a ការសិក្សា published Friday by the Centers for Disease Control and Prevention.

The study tracked incidences of myocarditis, a ជាធម្មតាស្រាល inflammation of the heart muscle that tends to affect បុរស, and pericarditis, a ជាធម្មតាស្រាល inflammation of the sac containing the heart, following Covid infection and following doses of Pfizer-BioNTech and Moderna’s mRNA vaccines.

The risk of heart complications after vaccination was highest among males age 12-17, especially following a second dose, when there was a roughly .04% (1 in 2,786) risk of developing myocarditis or pericarditis within 21 days—still 1.8 times lower than the roughly .07% (or 1 in 1,541) risk of developing those disorders following Covid infection for males in that age range.

Women were at lower risk than men of developing heart complications following vaccination, with women age 18-29—the highest-risk female group—reporting at most a .01% (or 1 in 17,241) risk of myocarditis or pericarditis within 21 days of vaccination.

These findings reinforced previous CDC research indicating that mRNA vaccines very rarely cause heart complications, and that male adolescents and young adults are at ហានិភ័យធំបំផុត, especially following their second shot.

Heart complications were so rare among some patient groups that it was difficult to precisely estimate how much lower the risk was after vaccination than after Covid infection, and some demographics—such as girls age 5-11—reported no heart complications following vaccination.

Researchers analyzed electronic health record data from January 1-31 from 40 U.S. healthcare systems participating in the National Patient-Centered Clinical Research Network.

Inflammation like myocarditis can be caused by immune response to common pathogens and, in rare instances, to vaccines, Yale pediatric cardiologist Dr. Jeremy Asnes បាននិយាយថា:. In most cases, patients who experienced myocarditis or pericarditis who sought treatment quickly improved with the help of medication and rest, the CDC រាយការណ៍. In 2021, the public collapses of apparently healthy young male athletes—such as Danish soccer player គ្រីស្ទានអ៊ីរីសេន and U.S. basketball player Keyontae Johnson-បានលើកឡើងពីការព្រួយបារម្ភ that vaccine-induced cardiac side effects might have been to blame. However, investigations into these and other athlete ដួលរលំ រកឃើញ។ គ្មានភស្តុតាង linking the incidents to vaccines. Sudden cardiac death is relatively common among athletes, affecting about 1 in 40,000 to 1 in 80,000 athletes annually, according to a 2016 ការសិក្សា published by the National Library of Medicine, which found sudden cardiac death to be the most common medical cause of death among athletes. Nonetheless, this rare association between vaccines and usually mild cardiac reactions has been spun by conspiracy theorists into ការទាមទារព្រៃ of dozens of vaccine-caused heart attack deaths among athletes. In 2021, the CDC launched an ការស៊ើបអង្កេតកំពុងបន្ត into incidences of ការរលាកបេះដូង នោះជា បានរកឃើញដំបូង among teenage boys who had received Pfizer or Moderna’s vaccines, but continues to recommend that everyone age 5 and older ចាក់វ៉ាក់សាំង. This recommendation is reinforced by Friday’s study, indicating that people in all age groups currently eligible for the vaccine are at a lower risk of heart complications after getting vaccinated than after catching Covid.

Johnson & Johnson and Janssen’s វ៉ាក់សាំង​ការពារ covid, which uses traditional, non-mRNA technology, has មិនបាន​បង្ហាញ the same pattern of rare cardiac side effects as Pfizer and Moderna’s vaccines. However, Johnson & Johnson’s vaccine carries a small risk of causing serious blood clots and is less effective at preventing Covid than Pfizer and Moderna’s vaccines, which has led the CDC to ចូលចិត្ត Pfizer and Moderna’s vaccines in most contexts.
