In the two years since COVID vaccines are publicly available, they have a popular target for misinformation. Anti-vaccine activists have made far-flung claims: vaccines adjust DNA, cause infertility, and implant magnetic devices so the government can track each of you. every move, without any credible clinical evidence. But they achieved one goal: More Americans than ever hesitant to get vaccinated.
So when a user has a rare side effect of COVID vaccines, the news spreads quickly. For example, the Florida surgeon general said that children between the ages of 18 and 39 do not receive mRNA injections, raising questionable condition research that claimed the threat of heart attack. Death increased to 84% after vaccination. More recently, other people were quick to blame Buffalo Bills player Damar Hamlin’s sudden cardiac arrest in early January on the NFL’s mandatory COVID vaccine requirement. However, cardiologists were just as quick to demystify perception. with more realistic medical explanations.
Infectious disease experts have been the threat of myocarditis since the beginning of the pandemic. Thousands of studies on COVID have been published, and some have uncovered a link between myocarditis and the virus and vaccines. These are the answers we have so far.
Myocarditis is a disease that causes inflammation in an intermediate layer of the central muscle called the myocardium. Inflammation affects the functioning of muscle cells and the center’s electrical system, causing abnormal central heartbeats and interfering with the pumping of blood to and from the body. The effects of your body’s immune reaction overreact to an infection you’re recently fighting. Viruses are the common cause of maximal myocarditis and are responsible for 1. 5 million cases a year.
Most cases of myocarditis are mild and on their own, says Keren Hasbani, a pediatric cardiologist at Pediatrix Pediatric and Congenital Cardiology Associates of Texas. Most go away in less than two weeks without headaches or need to go to the hospital.

Myocarditis that persists for more than two weeks is chronic and can lead to serious complications. The longer the inflammation stays in the center, the weaker the muscle becomes. Continued damage to the central cells can lead to permanent scarring of the central tissue, which can cause the disease. Roll back and accumulate the threat of stroke, central attack, central failure, or death.
Myocarditis can affect anyone, at any age. However, center disease occurs twice as often in young men as in women.
In some cases of myocarditis, it is possible for a user to spend the day not knowing that their center is inflamed. When there are symptoms, they can resemble those of a viral infection, adding fever, vomiting, headache and sore throat.
The maximum non-unusual sign of presentation of the disease is discomfort or a feeling of tightness in the chest area. Hasbani says the pain can occur anywhere between the left side and chest area. Instead of the pain you feel when you pull on a pectoral muscle, Hasbani says chest pain from myocarditis is described as pain that comes from a much deeper position in the body. “People often say it’s another kind of chest pain they’ve felt before. “
People with myocarditis also tend to describe immediate or immediate heartbeats because the inflammation affects the heart’s electrical system. Because the organ does not function to its full potential, blood is not distributed well to other parts of the body. This can lead to symptoms such as shortness of breath, especially since chest pain makes it difficult to breathe deeply. Lack of oxygen can cause dizziness and fainting. Less common symptoms include swelling of the legs, ankles, and feet due to lack of blood distribution.
While Hasbani says it’s incredibly rare, myocarditis can be life-threatening when the weakened center can’t meet the body’s demands. In those scenarios, the user would have to be hospitalized and given medications such as adrenaline to maintain the central heartbeat. A life device must also be supplied to oxygenate and pump blood. This allows the center to rest and recover from the damage caused by myocarditis.
COVID infections can cause severe and life-threatening cases of myocarditis, but overlap is still scarce. An estimated 40 out of 1 million people develop myocarditis 28 days after testing positive. Risks of inflammation accumulate in other people with severe COVID illness requiring hospitalization and others with pre-existing fitness issues, such as high blood pressure and obesity.
A 2021 study from the Centers for Disease Control and Prevention (CDC) found that the risk of myocarditis is 16 times higher in other people not vaccinated with COVID than in other unvaccinated people who have never had the disease. It also found that men and adults 50 and older are more vulnerable to the disease. Among unvaccinated youth under the age of 16, the risk of myocarditis is 37 times higher in those infected with COVID than in their healthy peers.

Hasbani says the explanation for why other people with myocarditis due to COVID infection have more severe headaches is that the framework is already overworked to cope with the significant damage the virus causes to other organs such as the lungs, kidneys and gastrointestinal tract. Center inflammation may take precedence over all other ongoing physical disorders and take longer to resolve. In children younger than 16, the CDC speculates that COVID-induced myocarditis may be just a sign of multisystem inflammatory syndrome, which is a life-threatening condition linked to the coronavirus.
Yes, however, the possibilities are incredibly rare. An August 2022 study in England estimated the rate of myocarditis-related hospitalizations and deaths at more than 42 million people aged thirteen and older. The subjects consisted of two other groups: other people fully vaccinated with the AstraZeneca, Moderna or Pfizer-BioNTech vaccines and other unvaccinated people who tested positive for COVID. The researchers found a 0. 007 percent, or 2681 out of 43 million vaccinated adults, chance of being hospitalized or dying from vaccine-related myocarditis. Only 0. 001% occurred within 28 days of receiving a COVID vaccine or booster. A separate study from October 2022 estimated that the risk of myocarditis is seven times higher in other unvaccinated people than in other vaccinated people.
So far, only mRNA vaccines have been linked to myocarditis. The threat appears to be greater in other people receiving a momentary dose of Moderna than in Pfizer-BioNTech, says Jayne Morgan, a cardiologist and clinical director of the COVID Task Force at Piedmont Hospital in Atlanta. The large-scale study conducted in England last year showed greater overlap of myocarditis cases with a momentary dose of Moderna. Meanwhile, the 2022 study measured a two- to three-fold increased risk of myocarditis after one time of the Moderna vaccine, with the most powerful disposition in men and others aged 18 to 39. Still, Morgan cautions that the rate is low compared to that of unvaccinated COVID populations.

Although the incidence is low, studies indicate that young men under 40 are at risk of developing myocarditis, Morgan says. A September 2022 study in Israel reported 28 mild cases of myocarditis after a booster shot of Pfizer-BioNTech, in nearly 4 million adults. The results showed that men aged 16 to 19 were at risk of myocarditis (a chance in 15,000), followed by men aged 20 to 24. All Americans made a full recovery after spending an average of 3. 5 days in the hospital.
There is no official explanation for why young men are at increased risk for myocarditis. Some COVID researchers have hypothesized that the SARS-CoV-2 spike protein from which mRNA vaccines were designed could cause an overactive immune reaction that causes inflammation of the center. That doesn’t mean the vaccine causes an infection, Hasbani warns: Instead, the immune formula reacts to the vaccine in a way that also reacts with cells in the center of the myocardium. The effect is almost temporary.
Hasbani says any medical treatment besides vaccines has side effects, including heart-related ones. The smallpox vaccine, for example, helped fight international smallpox in 1980, but was later found to have a 10% risk of mild myocarditis.
One of the most likely reasons we know more about the dangers of COVID vaccine myocarditis is that “we don’t vaccinate that many people as temporarily for express disease, and we follow a giant population so closely,” Hasbani says.
With all the facts, any of the experts points out that the low threat of myocarditis does not outweigh the severe headaches that a SARS-CoV-2 infection can have. For example, prolonged COVID remains a challenge for millions of patients and has been linked to much more persistent core challenges. “It’s much safer to get vaccinated and you and your family than to try your luck against COVID,” Hasbani adds.
If the vaccine causes central inflammation in someone, there is little chance that the disease will lead to central failure. A January 2022 investigation of more than 17 million people found only 627 cases (or 0. 0035%) of COVID vaccine-related myocarditis. Of these, another 626 people fully recovered and one user died. To put this in perspective, the National Institutes of Health states, “Your threat of contracting myocarditis after receiving a COVID vaccine is less than the threat of being struck by lightning in your lifetime. “
