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 57-year-old man with a history of hypertension, chronic obstructive pulmonary disease and obesity. He was found unconscious on the street at around midnight of May 2.

He was admitted to Pok Oi Hospital's accident and emergency department and passed away this morning.

The man had received a dose of the Sinovac vaccine at a community vaccination centre on April 26 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.
