The U.S. Food and Drug Administration (FDA) updated a warning to the Pfizer and Moderna Covid-19 vaccines’ patient and provider fact sheets on 26th June 2021, indicating a rare risk of heart inflammation.
The fact sheets for each vaccine were updated to include a warning concerning myocarditis and pericarditis after the second dosage, as well as symptoms appearing within a few days of receiving the shot.
The inflammation of the heart muscle is known as myocarditis, while the inflammation of the tissue around the heart is known as pericarditis. The benefits of getting the vaccination, according to health professionals, still exceed any risks.
Janet Woodcock, acting FDA commissioner reportedly said that given the number of vaccine doses that have been administered, the risk of myocarditis and pericarditis appears to be very low. She added that considering the danger of Covid-19 illnesses and related, possibly severe effects, the advantages of Covid-19 immunization continue to outweigh the risks.
The FDA announcement comes after a study and debate by the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention (CDC).
According to CDC, there have been over 1,200 incidences of myocarditis or pericarditis in patients aged 30 and under who received the doses. Almost 300 million injections had been given out as of June 11th, 2021. For Pfizer and Moderna vaccines combined, there were only 12.6 incidences of heart irritation per million doses.
