Myocarditis is a rare adverse event associated with receipt of COVID-19 mRNA vaccines; the overall reporting rates of myocarditis following COVID-19 mRNA vaccination were highest among males aged <18 years (5).
Can COVID-19 vaccines affect the heart of children?
Can COVID vaccines affect the heart? Hansen: For most kids, the vaccine will have no effect on their heart. But health officials are monitoring very rare occurrences of myocarditis and pericarditis after vaccination.
What are the average ages of people who had myocarditis after mRNA-based COVID-19 vaccination during the first 8 months of 2021?
Of the 1626 reports that met the CDCs case definition for myocarditis, 1195 (73%) were younger than 30 years of age, 543 (33%) were younger than 18 years of age, and the median age was 21 years (IQR, 16-31 years) (Figure 1).
Do mRNA COVID-19 vaccines cause heart inflammation?
These cases typically occur in male adolescents and young adults after the second dose, and within a week of vaccination. It is important to seek medical care if symptomatic (chest pain, shortness of breath, having a fast beating, fluttering, or pounding heart).
What you need to know about myocarditis and the COVID-19 vaccine
Can COVID-19 cause heart problems?
For people who have had COVID-19, lingering COVID-19 heart problems can complicate their recovery.
Some of the symptoms common in coronavirus “long-haulers,” such as palpitations, dizziness, chest pain and shortness of breath, may be due to heart problems — or, just from having been ill with COVID-19.
The Pfizer and Moderna vaccines were created using messenger RNA (or mRNA) technology, which has been used for about 10 years in cancer treatment, with no long-term effects detected. And even before that, scientists had been working with mRNA technology for years. 3. mRNA technology does not alter your DNA.
How common is myocarditis in young men during the COVID-19 pandemic?
The researchers found an excess rate of myocarditis of 3.26 per 100,000 individuals within 28 days of a positive COVID-19 test among all males, and 1.37 per 100,000 individuals among males 16 to 24 years of age.
How do you know if you have myocarditis from the Pfizer COVID-19 vaccine?
Symptoms include chest pain, palpitations (the feeling of one's heart beating very fast), and shortness of breath. If your child develops any of these symptoms after receiving the COVID-19 vaccine, please contact your pediatrician and seek medical care.
What are some symptoms of the COVID-19 BA.5 subvariant?
According to the University of California Davis Health, the reported symptoms of BA.5 are similar to previous COVID variants: fever, runny nose, coughing, sore throat, headaches, muscle pain and fatigue.
In general, children who get sick with the coronavirus do not have serious problems as often as adults do. But a very rare complication of COVID-19 called multisystem inflammatory syndrome in children, or MIS-C, can cause serious heart damage, cardiogenic shock or death.
What are the possible rare heart complications after COVID-19, in children?
While heart complications after SARS-CoV-2 infection are uncommon in children, some experience abnormal heart rhythm, inflammation in and around the heart muscle or multisystem inflammatory syndrome in children (MIS-C), a new condition identified during the pandemic.
Do children recover completely in the rare event of myocarditis after the COVID-19 vaccination?
Millions of people worldwide have received the mRNA vaccine without serious side effects. Serious side effects resulting from the vaccine—including myocarditis—are extremely rare. In most cases of vaccine-associated myocarditis, kids recovered completely after receiving medication.
Viruses are a common cause of heart inflammation – known as myocarditis – and the coronavirus is no different. The Centers for Disease Control and Prevention reported in September research showing patients with COVID-19 had nearly 16 times the risk of myocarditis compared with patients without COVID-19.
Several cases of myocarditis and pericarditis have been reported after mRNA COVID-19 vaccination. Interestingly, most cases were seen in male adolescents and young adults, commonly after 3-4 days of the second dose of mRNA vaccine.
What is known about the COVID-19 vaccine related myocarditis in people younger than 21?
DALLAS, Dec. 6, 2021 — Most young people under the age of 21 who developed suspected COVID-19 vaccine-related heart muscle inflammation known as myocarditis had mild symptoms that improved quickly, according to new research published today in the American Heart Association's flagship journal Circulation.
What is the difference between myocarditis and pericarditis in the context of COVID-19?
Myocarditis is inflammation of the heart muscle, and pericarditis is inflammation of the outer lining of the heart. In both cases, the body's immune system causes inflammation in response to an infection or some other trigger.
Are males at increased risk of developing myocarditis from COVID-19?
Conclusions: Myocarditis (or pericarditis or myopericarditis) from primary COVID19 infection occurred at a rate as high as 450 per million in young males. Young males infected with the virus are up 6 times more likely to develop myocarditis as those who have received the vaccine.
COVID-19 can cause myocarditis, which is an inflammation of the heart muscle. This condition should be fully resolved before a return to sports activities. Any symptoms of chest pain, shortness of breath, lightheadedness, fainting or heart palpitations could indicate myocarditis.
"A significant percentage of men will experience testicular swelling or swelling of the epididymis after symptomatic COVID-19 infection," says Dr. Deibert. A recent review of male reproductive health estimates that "10% to 22% of men with acute COVID-19 infection develop orchitis or epididymo-orchitis.
mRNA vaccines have been studied before for flu, Zika, rabies, and cytomegalovirus (CMV). As soon as the necessary information about the virus that causes COVID-19 was available, scientists began designing the mRNA instructions for cells to build the unique spike protein into an mRNA vaccine.
