British health chiefs have quietly released a warning that Pfizer and Moderna's Covid vaccines may cause heart damage, MailOnline can reveal. But in rare cases when inflammation is severe, there can be damage to the heart which needs monitoring and possibly a heart transplant. If health chiefs make the same ruling for that vaccine, it means under-40s will still only be able to get Pfizer or Moderna until other candidates come on stream. The US Centres for Disease Control and Prevention last month said there was a 'likely association' between the Pfizer and Moderna jabs and myocarditis and pericarditis in young adults. 'The available evidence for AstraZeneca's Covid vaccine does not suggest an increased risk of myocarditis or pericarditis.
