The Department of Health said that in the preceding week ending June 20, it received 142 reports of adverse events following COVID-19 immunisation.
Among them, no death case was reported by the Hospital Authority involving individuals who had received vaccines within 14 days before they passed away and had potential association with vaccination.
As at 8pm on June 20, over 3.22 million doses of COVID-19 vaccines had been administered to the public.
The department received 3,747 reports of adverse events, 22 of which are death cases with vaccination within 14 days. The figures represented 0.12% and 0.0007% of the total vaccine doses administered.
As at June 20, the Expert Committee on Clinical Events Assessment Following COVID-19 Immunisation concluded that six death cases had no causal relationship with vaccination, and preliminarily considered that 15 cases were not associated with vaccination. One case was pending assessment.
The committee considered that there is no unusual pattern identified so far, and will continue to closely monitor the situation and collect data for assessment.
According to information from the authority, during the period from May 24 to June 20, the ratio of death cases out of those without a vaccination record was 60.3 cases for every 100,000 people, whereas the ratio of death cases for those with a vaccination record was 2.9 cases for every 100,000 people. The overall death rate is similar to that recorded in the past three years.
Out of those without a vaccination record, the ratio of death cases with acute stroke or acute myocardial infarction was 2.7 cases for every 100,000 people, whereas the ratio of death cases under the same category for those with a vaccination record was 0.2 cases for every 100,000 people.
Furthermore, the ratio of miscarriage cases out of those without a vaccination record was 25.9 cases for every 100,000 people, whereas the ratio of miscarriage cases for those who had a vaccination record was 5.5 cases for every 100,000 people.
Based on the statistical analysis of the above figures, there is no evidence that vaccination increases the risk of death or miscarriage for recipients.
The relevant reference statistics will be uploaded to the COVID-19 Vaccination Programme thematic website.
The majority of non-death cases of adverse events received so far are relatively minor, details of which can be found here.
