Serious Heart Inflammation 44 Times Higher After Covid Vaccination, Nature Study Finds

(by Will Jones | The Daily Skeptic) – The risk of being hospitalised with heart inflammation is up to 44 times higher following Covid vaccination, a study in Nature has found.

The study, which examined the vaccination status of all 1,612 hospital cases of myocarditis and 1,613 hospital cases of pericarditis in France between May 12th and October 31st 2021, found that the risk of being hospitalised with myocarditis was 8.1 times higher in the week following a Pfizer second dose (95% confidence interval [CI], 6.7 to 9.9) and 30 times higher following a Moderna second dose (CI, 21 to 43).

When the findings are broken down by age, elevated risks are found in younger adults. In the week following a Moderna second dose, the risk for males aged 18-24 was 44 times higher (CI, 22–88) and for females was 41 times higher (CI, 12–140). The risk following a Pfizer second dose decreased with age, peaking at 18 times higher in males aged 12-17 (CI, 9–35), whereas the risk from the higher-dose Moderna vaccine did not decrease with age. The results by age are depicted in the chart below (note the logarithmic scale, which compresses the higher numbers).

The following table displays the overall results.

The rate of myocarditis hospitalisation following vaccination was one every 5,900 second Moderna doses (CI, 4,400-8,000) and one every 21,100 second Pfizer doses (CI, 17,400-26,000) among 18-24 year-old males. Among 18-24 year-old females the rate was one every 18,700 second Moderna doses (CI, 11,000-33,400). The full breakdown by age and sex is shown below. Read Full Article >
