Serious heart inflammation ‘up to 44 times higher after Covid jab’


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 12 and October 31 2021, found that the risk of being hospitalised with myocarditis was 8.1 times higher in the week following a Pfizer second dose (95 per cent 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 dose (CI 4,400-8,000) and one every 21,100 second Pfizer dose (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 dose (CI 11,000-33,400). The full breakdown by age and sex is shown below.

The researchers explain why their evidence is strongly indicative of a causal relationship between the vaccines and heart inflammation.

  1. ‘The associations remained strong even after adjusting for a history of these conditions or recent SARS-CoV-2 infection, and in a period during which most common respiratory viruses were not widely circulating.’
  2. ‘The time that elapsed between exposure to the vaccine and hospitalisation was very short for both conditions, particularly after the second dose.’
  3. ‘In most cases, the associations did not persist after seven days following exposure.’
  4. ‘The stronger risk associated with the second dose and the mRNA-1273 [Moderna] vaccine, which contains a larger amount of mRNA, suggest a dose response relationship.’

Noting the study’s short follow-up time, the authors recommend that future studies should be based on a longer period of observation and so investigate the risk related to the ‘booster’ doses of the vaccines and any long-term consequences of the heart inflammation. They also noted that any milder myocarditis cases not requiring hospital treatment were not included in the current study.

The findings are in line with those of other studies, including one from Scandinavia published in the Journal of the American Medical Association (JAMA) in April, which found the risk of hospitalisation with heart inflammation was many times higher following vaccination with an mRNA Covid vaccine.

With healthy young adults at low risk of developing serious Covid, and heart inflammation just one of many adverse effects of the Covid vaccines, isn’t it time these vaccines were withdrawn for younger people?
