The Department of Health said that in the week ending May 15, it received 28 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 died and had potential association with vaccination.

As at 8pm on May 15, around 16.45 million doses of COVID-19 vaccines had been administered to the public.

The department received 7,484 reports of adverse events, of which 103 were death cases with vaccination within 14 days. The figures represented 0.05% and 0.0006% of the total vaccine doses administered. None of the death cases was associated with vaccination.

The Expert Committee on Clinical Events Assessment Following COVID-19 Immunisation concluded that 61 death cases had no causal relationship with vaccination, and preliminarily considered that 11 cases were not associated with vaccination. The remaining 31 cases are pending further information for assessment.

The committee considered that there is no unusual pattern identified so far.

According to information from the authority, during the period from April 18 to May 15, the ratio of death cases out of those without a vaccination record was 258.6 cases for every 100,000 people, whereas the ratio of death cases for those with a vaccination record was 29.8 cases for every 100,000 people.

Out of those without a vaccination record, the ratio of death cases with acute stroke or acute myocardial infarction was 9.4 cases for every 100,000 people, whereas the ratio of death cases under the same category for those with a vaccination record was 1.7 cases for every 100,000 people.

Furthermore, the ratio of miscarriage cases out of those without a vaccination record was 142.2 cases for every 100,000 people, whereas the ratio of miscarriage cases for those who had a vaccination record was 10.2 cases for every 100,000 people.

Based on the statistical analysis of the 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 ones, details of which can be found here.
