Pfizer and Moderna’s Covid vaccines have been linked to relatively rare cases of myocarditis, but crucially, studies suggest this does not lead to have a higher risk of having a cardiac arrest. Myocarditis is more common and serious after Covid infections than after a vaccine. However, there is evidence cardiac arrests are more common in athletes than in the general population. Young athletes are more likely to experience a cardiac arrest than others their age. Twitter – which is in the process of rebranding itself as X – allows its users to produce “community notes”. An unfounded belief Covid vaccines are leading to a rise in heart problems, especially in young athletes, has been amplified by Twitter owner Elon Musk. What is your take on these claims ?
