2021年3月6日,政府傳染病顧問專家、香港大學微生物學教授袁國勇為自己注射復比泰BioNTech疫苗。(見圖示,醫管局提供)。這種做法,據說該可以令疫苗可以有較長的路徑經身體的淋巴結吸收和誘發免疫抗體反應,而不會有太快進入心臟的風險。
2012年3月28日,《明報》報導袁國勇介紹三種注射方法的分別,但語焉不詳://疫苗接種的方式有很多,港大微生物學系講座教授袁國勇早前更自行在前臂打針,還說:「呢個皮內注射,好痛㗎,不過正嘢嚟。」疫苗接種一般分肌肉注射、皮下注射、皮內注射3種,注射藥物和注射疫苗的方式有不同考量。//
2021年11月28日,一篇有袁國勇名字(Kwok Yung Yuen, MD, FRCPath)在內的香港的研究團隊撰寫的醫學研究論文(Epidemiology of Acute Myocarditis/Pericarditis in Hong Kong Adolescents Following Comirnaty Vaccination. Gilbert T Chua et al. Clinical Infectious Diseases, ciab989, Accepted Manuscript. Received: 25 September 2021. Published: 28 November 2021. Oxford Academic.

//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.

該論文於今年九月十五日提交,今年十一月二十八日認可為接納草稿。
2021年11月11日,科興疫苗公司申請降低接種年齡為3至17歲,袁國勇倡學童打復必泰改為大腿注射,減心肌炎風險。他說手臂近心臟,疫苗或會經過淋巴腺進入靜脈,對心臟構成影響,有關情况於老鼠實驗上證實;如改打大腿,經過多重淋巴結過濾,會較安全。
2021年11月12日,袁國勇表示,估計本港下周將決定將兩種疫苗接種年齡,降低到3至12歲兒童。他指文獻顯示12至19歲青少年接種由內地及德國研發的復必泰疫苗後,每百萬人有60人患心肌炎,比例低而且徵狀輕微,3至12歲兒童接種劑量更只是成人的三分一,如果在大髀注射,安全性會更高。
筆者不熟悉袁國勇引述的醫學研究文獻,但上述的牛津學刊的論文,美國的Robert W Malone MD, MS的網誌2021年12月5日(今日)如此判斷:2680青少年之中有1名誘發急性心肌炎或心包炎。
Malone 醫學博士的判斷如下,心肌炎或心包炎並無溫和的看法。兩種都會損害心臟,而心臟肌肉是無法自行修補的,炎症留下的疤痕是終身的,而且會引起猝死,尤其是在心臟受到緊張的時候:
//Many pediatric cardiologists including my colleague and friend Dr. Kirk Milhoan, MD, PhD (MD board certified in pediatric cardiology, PhD. in vascular inflammation) assert that there is no such thing as “mild” myocarditis in children. Myocarditis causes heart damage. Heart damage is for life - the heart does not heal by replacing damaged cells. It scars. Scars in the heart can lead to changes in electrical conduction in heart muscle, which in turn can result in “sudden death” due to changes in heart beat regularity and muscular contraction of the heart. These events may happen at any time, particularly when the heart is stressed in some way.//
也就是說,報給醫管局的心肌炎/心包炎個案是嚴重的,而且頗多也許是由於症狀輕微而沒有注意。港府急於向青少年推廣復必泰疫苗是不負責任,而且青少年患上感冒一般不會發病。
昨日的新聞,三百萬英國人在疫病解封之後,發現心臟出事,醫師說是疫後的心理壓力,是PPSD,即是創傷後壓力症候群云云。

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.
