22nd July 2021 – (Hong Kong) Earlier, three teenagers in the age group of 12 to 15 were suspected of developing myocarditis after receiving Comirnaty vaccine.

Professor Dr Ivan Hung, co-convenor of the Expert Committee on Clinical Events Assessment Following COVID-19 Immunisation said on a radio program this morning that parents or young people do not need to worry too much, because the chance of myocarditis after the injection is rare, even if the symptoms appear, they are normally mild. The recovery rate is also high, and young people are reminded that they should rest more in the first week after being vaccinated with Comirnaty and reduce strenuous exercise. If they feel unwell after the first injection, they can undergo a cardiac assessment, such as ultrasound, before deciding whether to vaccinate the second dose.

He quoted relevant data from Israel and the United States, saying that people under 30 years of age are more likely to have myocarditis, especially those under 16 years of age. The cause is still not clear, but it is believed to be related to the immune mechanism reaction.

On the contrary, anyone who are infected with COVID-19 may develop severe myocarditis.
