Abstract

Background

Age-specific incidence of acute myocarditis/pericarditis in adolescents following Comirnaty vaccination in Asia is lacking. This study aimed to study the clinical characteristics and incidence of acute myocarditis/pericarditis among Hong Kong adolescents following Comirnaty vaccination.

Methods

This is a population cohort study in Hong Kong that monitored adverse events following immunization through a pharmacovigilance system for COVID-19 vaccines. All adolescents aged between 12 and 17 years following Comirnaty vaccination were monitored under the COVID-19 vaccine Adverse Event Response and Evaluation Programme. The clinical characteristics and overall incidence of acute myocarditis/pericarditis in adolescents following Comirnaty vaccination were analysed.

Results

Between 14 June 2021 and 4 September 2021, 33 Chinese adolescents who developed acute myocarditis/pericarditis following Comirnaty vaccination were identified. 29 (87.88%) were males and 4 (12.12%) were females, with a median age of 15.25 years. 27 (81.82%) and 6 (18.18%) cases developed acute myocarditis/pericarditis after receiving the second and first dose, respectively. All cases are mild and required only conservative management.The overall incidence of acute myocarditis/pericarditis was 18.52 (95% Confidence Interval [CI], 11.67-29.01) per 100,000 persons vaccinated. The incidence after the first and second doses were 3.37 (95%CI 1.12-9.51) and 21.22 (95%CI 13.78-32.28 per 100,000 persons vaccinated, respectively. Among male adolescents, the incidence after the first and second doses were 5.57 (95% CI 2.38-12.53) and 37.32 (95% CI 26.98-51.25) per 100,000 persons vaccinated.

Conclusions

There is a significant increase in the risk of acute myocarditis/pericarditis following Comirnaty vaccination among Chinese male adolescents, especially after the second dose.

IBTFR$$ claim....oh, these are only MILD cases.

RE: IBTFR$$ claim....oh, these are only MILD cases.

So, mild Myocarditis cases are an acceptable risk to take for Comirnaty vaccination ( yep, the one actually APPROVED by the FDA )?

[Jane Long]

Exactly.

Don’t be surprised if we see them ($hot $hills) claim this.

I presume that the name “Comirnaty” was chosen because the name “Myocarditis-Inducing Poison” was too obvious.

“journo” calls it “rare” in sub-heading; Madgen says doc called it “common”. Australia started with AZ, then Pfizer...and they always call it Pfizer. however, it could actually be Comirnaty, from what I understand (who knows?). so much is deliberately confusing:

Former Aussie basketball star Ben Madgen says he was hospitalised with a rare inflammatory heart condition after his Covid-19 vaccine.

“Ended up in the emergency room on Wednesday night after taking the second Pfizer shot,” the 36-year-old wrote.
“Diagnosed with pericarditis. The doctor said this is now common after the Pfizer shot, especially with teenage boys and young males.”...

See tag. Ivermectin and HCQ work to defeat the CCP virus.

Odd that one part says cases were mild and another says significant risk of acute.
