Kaiser Permanente study shows myopericarditis is 43 times higher than VAERS reports

Posted on by Jesse Santiano, M.D.

Kaiser Permanente Northwest studied 65,785 members aged 18-39 who received a COVID-19 vaccine booster shot at least five months following the primary series. They looked for the ‘myocarditis’ and ‘pericarditis’ diagnosis codes in all outpatient and inpatient encounters until January 18, 2022.

Myocarditis is the inflammation of the heart muscles, and pericarditis is the inflammation of the sac surrounding the heart. Both coexist in myopericarditis.

Their search revealed six patients who had confirmed or probable CDC case definition of acute myocarditis or pericarditis within 21 days of a COVID-19 booster dose. Four cases occurred in 27,253 men.

Overall, the study estimated 9.1 cases of post-booster myopericarditis per 100,000 booster doses given. In men, myopericarditis estimate is 4.7 cases per 100,000 booster doses.

All six patients received Pfizer shots as the booster dose. After his booster dose, one patient developed chest pain, myocarditis, and cardiogenic shock. Another patient had mild myocarditis following a mix and match shots with Johnson and Johnson initially followed by a booster dose of the Pfizer jab.

In the Vaccine Adverse Event Reporting System (VAERS), there are 54 preliminary reports of vaccine-related myopericarditis. Twelve are confirmed and 38 under review, following 26.3 million booster doses given across all ages, with an unadjusted estimate of 0.21 cases per 100,000 doses.

Based on their findings of 9.1 cases of myopericarditis per 100,000 booster doses and the VAERS data showing 0.21 cases/100,000. The myopericarditis cases in the VAERS system are underreported by a factor of 43.33.

The EKG below shows the diffuse ST-segment elevation in all leads characteristic of myopericarditis.
