The Department of Health said as of 4pm today, in the past 24 hours it received one report from the Hospital Authority of a death case with suspected serious adverse event following COVID-19 vaccination.

The case involved a 46-year-old man who was a smoker with a history of hypertension. He complained of chest pain on May 4 but had not sought medical advice. He was found unconscious at home in the evening of May 5.

He was admitted to Mui Wo General Out-patient Clinic but passed away after failure in resuscitation.

The man had received the second dose of the BioNTech vaccine at a community vaccination centre on April 27 and there was no record of him feeling unwell during observation there.

The department has contacted the authority to obtain further information and will pass the case to the Expert Committee on Clinical Events Assessment Following COVID-19 Immunisation for causality assessment.

So far, there is no clinical evidence to indicate that the event was caused by the vaccine, it added.
