The US Centers for Disease Control and Prevention (CDC) is currently conducting a probe into reports of heart problems among a small number of teenagers and young adults who were vaccinated against COVID-19.
The CDC is reviewing reports of a condition known as myocarditis, or inflammation in the heart muscle, after receiving the vaccine, according to a report in the New York Times, citing the CDC's vaccine safety group.
The condition appeared in some adolescents and young adults about four days after the second dose of the Moderna and Pfizer vaccine.
The CDC reportedly said that the review was in its early stage, and there were "relatively few" cases and it could be unrelated to the vaccination.
