A Centers for Disease Control and Prevention (CDC) advisory panel is set to meet Wednesday to discuss reports of myocarditis and pericarditis in some COVID-19 mRNA vaccine recipients. Leading up to ...

Inflammation resulting from a viral infection has traditionally been thought to cause acute myocarditis, which can lead to fatal heart arrhythmias in otherwise healthy young adults. Now, a new study ...

Mounting data on mRNA vaccination against COVID-19 continued to suggest a small excess risk of myocarditis, especially in young men and adolescent boys. Based on voluntary reports to the passive ...

Myocarditis describes inflammation of heart tissue known as the myocardium. This inflammation can affect the electrical system of the heart and reduce the heart’s ability to pump blood around the body ...

Reports have suggested an association between the development of myocarditis and the receipt of messenger RNA (mRNA) vaccines against coronavirus disease 2019 (Covid-19), but the frequency and ...

Now that hundreds of millions of doses of COVID-19 vaccines have been administered in the U.S., an abundance of safety data has been collected. While this data shows that COVID-19 vaccines are safe ...

A new study sheds light on what may be causing very rare cases of heart inflammation in young men after receiving an mRNA Covid vaccine. Early hypotheses as to what was driving the heart inflammation, ...

(UPDATED) The US Centers for Disease Control and Prevention (CDC) is reporting a higher-than-expected number of myocarditis cases among young people who received the Pfizer/BioNTech or Moderna ...

Multiple studies have shown that in rare cases, teen and young adult males have developed myocarditis after getting the mRNA COVID-19 vaccine — and now new research published in the journal Science ...

Myocarditis is a condition in which your heart muscle, called the myocardium, becomes inflamed. It affects your heart’s electrical signal and may cause a rapid or abnormal heart rhythm (arrhythmia).
