the Pfizer and Moderna vaccines - might slightly increase the incidence of myocarditis in young people. That said, anecdotes reported by doctors in medical journals and reports to VAERS suggest that both of the mRNA vaccines authorized for use in the U.S. But as NPR's Geoff Brumfiel has reported, "when millions of people are vaccinated within a short period, the total number of these reported events can look big." The database is just meant as a starting point for further investigation and not proof of cause and effect. Many of the events reported turn out to be coincidental - not caused by a vaccine. Several hundred reports about the inflammation have been filed with the federal government's Vaccine Adverse Event Reporting System, or VAERS that's a repository of reports sent in by health professionals and patients about any health events they spot in the hours or days after vaccinations. "Although they appear with some symptoms of chest pain, and maybe some findings on EKGs, all of the cases we've seen have been on the mild end of the spectrum," he says. Pediatric cardiologist Stuart Berger of the Northwestern University Feinberg School of Medicine, a spokesperson for the American Academy of Pediatrics, says vaccine-related myocarditis in teens is not all that worrisome. In a case study of seven teenagers who got myocarditis following vaccination published last week in the journal Pediatrics, all seven got better after routine treatment with anti-inflammatory drugs. It's often mild enough to go unnoticed, but a full-blown case in adults can cause arrhythmias and heart failure that require careful treatment with multiple medications, and several months of strict rest. Symptoms include chest pain and shortness of breath.
Other causes include toxins and allergies. SARS-CoV-2, the virus that causes COVID-19, can trigger it, and so can cold viruses, and staph and strep and HIV. and around the world each year, often triggered by the body's immune response to infections. Long before the pandemic, thousands of cases of myocarditis were diagnosed in the U.S. Myocarditis is an inflammation of the heart muscle, and pericarditis, also being investigated, is an inflammation of the sac around the heart. So, should parents of teens hesitate to have their kids vaccinated against COVID-19?
However, if a person develops myocarditis after the first dose of one of the mRNA vaccines, a second dose should be delayed until the condition has fully resolved and the heart has returned to a normal state. The CDC says the findings do not change the basic recommendation that all people 12 and older should be vaccinated against COVID-19. The rate seen after these vaccines is slightly higher than the "background" rate. Naturally occurring heart inflammation is rare, but it does occur from time to time in teens and young adults.
Symptoms can include chest pain or pressure and a temporarily abnormal ECG and blood test results. The cases have been seen mostly in teens and young adults between 12 and 39 years old, the agency says. Still, soon after the Food and Drug Administration authorized the use of Pfizer's vaccine in young people, federal agencies began receiving reports of mild chest pain or other signs of possible heart inflammation (known as myocarditis) in a small percentage of teens and young adults soon after vaccination.Ĭoronavirus Updates CDC Says Kids As Young As 12 Should Get The Pfizer COVID-19 VaccineĪccording to the CDC, after a meeting of expert advisors discussed the data Wednesday, more than 300 cases of heart inflammation have been documented after the Pfizer or Moderna COVID-19 vaccines. teens and preteens (ages 12 through 17) had received at least one dose of a COVID-19 vaccine so far. The Centers for Disease Control and Prevention has recommended that everyone 12 and older get vaccinated against COVID-19, and the rollout is well underway: According to the CDC last week, around 7 million U.S. It's been a little more than a month since adolescents as young as 12 became eligible in the United States to receive the Pfizer vaccine against COVID-19, and nearly all reports have been positive: The vaccine is very effective in this age group, and the vast majority of kids experience mild side effects, if any - the same sore arm or mild flulike symptoms seen among adults who get the shot. teens and preteens (ages 12 through 17) have received at least one dose of a COVID-19 vaccine so far, the CDC says.Įva Marie Uzcategui/Bloomberg via Getty Images A teen gets a dose of Pfizer's COVID-19 vaccine last month at Holtz Children's Hospital in Miami.
