The Centers for Disease Control and Prevention (CDC) convened an “emergency meeting” on 226 cases of heart infections in people who received either the Pfizer or Moderna COVID-19 vaccine.
US health officials said Thursday that they are apparently looking at higher than expected reports of heart inflammation in teenage males and young adults after receiving their second dose.
A total of 226 cases have been reported that, according to the shots, could correspond to the CDC’s “work case definition” of myocarditis and pericarditis, the agency said.
Of the 226, three are in intensive care, 15 are being hospitalized, and 41 have persistent symptoms. The rest has recovered.
The cases seem to be more common in men and in younger people.
Myocarditis is inflammation of the heart muscle and pericarditis is inflammation of the outer wall of the heart.
It is not clear whether any of the conditions were caused by the gunfire, and reports of cases are extremely rare.
The CDC continues to urge everyone 12 and older to get vaccinated.

These types of heart infections can be caused by a variety of infections, including a bout of COVID-19, as well as certain medications.
There have been rare reports of other types of vaccinations in the past.
More than 130 million Americans have received both their first and second doses of the Pfizer and Moderna vaccines.
This means that only 0.000173846 percent of people given their second dose reported such an effect.
Cases are reported through the US Vaccine Adverse Event Reporting System (VAERS).
The system accepts reports from anyone regardless of the plausibility of the vaccine causing the symptom.
In total, VAERS received 573 reports of myocarditis and pericarditis after the patient received their second dose.
A total of 372 reports were from people who had the Pfizer vaccine while the remaining 201 had Moderna.

WHAT IS MYOCARDITIS?
Myocarditis is inflammation of the heart muscle. There are no specific causes for the condition, but it is usually caused by a virus.
Some of the most common infections that cause myocarditis are adenovirus and Coxsackie B.
It can be caused by the common cold, hepatitis B and C, and herpes simplex virus.
The most common symptoms of the disease are chest pain, fever, fast heartbeat, fatigue, and shortness of breath.
If the inflammation damages the heart muscle or the fibers that carry electrical impulses to the heart, complications can arise.
They can develop quickly and include a sudden loss of consciousness, an unusually fast, slow, or irregular heartbeat.
In very severe cases, the condition is fatal and leads to heart failure or sudden death. The inflammation enlarges the heart and creates scar tissue, forcing it to do more work, making it weaker.
In most cases of viral myocarditis, the disease goes away and there are no complications.
In rare cases, however, severe inflammation can cause heart damage that may require monitoring and possibly a heart transplant.
Myocarditis can recur, but there is no known way to prevent it from happening. According to the Myocarditis Foundation, the risk of recurrence is low at around 10 to 15 percent.
It is difficult to estimate the prevalence of myocarditis because there is no commonly available test for it.
In 2010, around 400,000 people worldwide died from heart muscle disease – cardiomyopathy, which includes myocarditis.
Expert opinion suggests that up to 40 percent of dilated cardiomyopathy is due to myocarditis, according to the National Organization for Rare Disorders.
Another 216 cases of heart inflammation were also reported after the first dose of the vaccines.
More than half of the cases reported after receiving the second dose were in people between the ages of 12 and 24, the CDC said.
This group accounts for less than 9 percent of the doses administered.
Almost two fifths of the cases were male.
The vast majority of cases occurred within a week of vaccination.
Symptoms included chest pain and difficulty breathing.
The CDC’s Vaccine Advisory Committee will meet on June 18 to further assess the potential risk.
Dr. Tom Shimabukuro told the government about the investigation at a government vaccine meeting Thursday.
“It’s a bit of a comparison between apples and oranges because these are again preliminary reports,” he said.
“Not all of them will turn out to be true myocarditis or pericarditis reports.”
Shimabukuro said the CDC results are largely in line with results from the Israeli Ministry of Health, which first reported a likely association with the Pfizer vaccine and the disease in young men.
Israel claimed in early June that its research showed that Pfizer’s vaccine was the “likely” cause of heart infection in a very small number of people who received the vaccine.
The Ministry of Health identified 148 cases of myocarditis shortly after the patient was vaccinated.
A total of 275 cases were discovered among the more than five million people administered the Pfizer jab in Israel, which had one of the most successful jab rollouts in the world.
The remaining 127 cases are unclear whether they are vaccine-related.
This was equivalent to just 0.005 percent of recipients, or one in 20,000 people.
Of the 148 cases that were “likely” vaccinated, the rate was 0.003 percent – although half of them had other health problems.
Israel’s warning was one of the first health concerns related to the Pfizer vaccine.
The AstraZeneca and Johnson & Johnson vaccines have both been screened for possible – extremely rare – links to blood clots.
