Covid vaccination increases the risk of severe heart inflammation up to 120-fold, a major study from Scandinavia published in the Journal of the American Medical Association (JAMA) has found.
The study looked at over 23 million patient records covering the over-12s populations of Denmark, Finland, Norway and Sweden from the start of the vaccine rollout in December 2020 to October 5th 2021.
For young males aged 16-24 years within 28 days of a second dose the study found severe myocarditis (requiring inpatient hospital admission) around five times more common after Pfizer and 14 times more common after Moderna. This corresponded to six events per 100,000 people after Pfizer and 18 events per 100,000 after Moderna. A second dose of Moderna given after a first dose of Pfizer came with even higher risk: a 36-fold increased risk, corresponding to 27 events per 100,000 people. The Moderna vaccine has three times the dose of mRNA of the Pfizer vaccine, which the authors suggest lies behind the increased risk.
The authors observe that of the 213 severe myocarditis cases in the 28-day risk window after a second dose of mRNA vaccine, 135 occurred within the first week. This is more than half, meaning the risk in that week is greatly elevated. Among males aged 16 to 24 years, the risk was around 13-fold greater during the week after a second dose of Pfizer and 38-fold greater after a second dose of Moderna. For a second dose of Moderna where the first dose was Pfizer the risk was 120-fold greater.
It’s worth noting that the bar for myocarditis here is very high, excluding even those who receive medical attention as a hospital outpatient, let alone anything milder; even the milder cases, however, may cause long-term damage….
