As reported by GreatGameIndia earlier, the US CDC and FDA had lifted their recommended pause on use of Johnson & Johnson’s coronavirus vaccine with a condition that it should include a safety label warning that its vaccine comes with blood clot risks. Now, Moderna has also been included.
For each vaccine, the fact sheets were revised to include a warning about myocarditis and pericarditis after the second dose and with the onset of symptoms within a few days after receiving the shot.
Inflammation and swelling of the heart, a condition known as Myocarditis, has been identified in many youngsters who have received their dose of Pfizer-BioNTech COVID-19 vaccine.
Myocarditis is a heart condition that leads to the inflammation of the heart muscles. The inflammation is a result of the body’s immune response to a certain infection, which leads to weakening and swelling of the heart.
