In the preceding week till 11.59pm on October 30, the Department of Health (DH) received 11 reports (Note 1) of adverse events following COVID-19 immunisation. No death cases were reported by the Hospital Authority (HA) involving individuals who had received vaccines within 14 days before they passed away and had potential association with vaccination.
As at 8pm on October 30, around 19.81 million doses of COVID-19 vaccines had been administered for members of the public. Around 6.89 million people had received at least one dose of vaccine, including 94.9 per cent of the population aged 12 or above. The DH received 8 017 reports of adverse events (0.04 per cent of the total vaccine doses administered). Among the death cases concerning persons who had been vaccinated, including 120 cases (Note 2) with vaccination within 14 days before they passed away (0.0006 per cent of the total vaccine doses administered), none of the death cases were associated with vaccination.
As of today, the Expert Committee on Clinical Events Assessment Following COVID-19 Immunisation had concluded that 111 death cases had no causal relationship with vaccination, while for one case the causal relationship with vaccination could not be established, and preliminarily considered that four cases were not associated with vaccination. Four cases are still pending further information for assessment. The Expert Committee considered that there is no unusual pattern identified so far, and will continue to closely monitor the relevant situation and collect data for assessment.
According to information from the HA, during the period from October 3 to October 30, the overall ratio of death cases was 48.3 cases for every 100 000 people, whereas the average ratio of death cases for the same period in 2018 to 2020 was 44.1 cases for every 100 000 people. Among these death cases, the ratio of death cases with acute stroke or acute myocardial infarction was 2.2 cases for every 100 000 people, whereas the average ratio of death cases under the same category for the same period in 2018 to 2020 was 2.8 cases for every 100 000 people. Furthermore, the ratio of miscarriage cases was 13.7 cases for every 100 000 people, whereas the average ratio of miscarriage cases for the same period in 2018 to 2020 was 19.2 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 thematic website for the COVID-19 Vaccination Programme.
The majority of non-death cases of adverse events received so far are relatively minor cases. The relevant details can be found in the "Report on the Safety Monitoring of COVID-19 Vaccines in Hong Kong" (www.drugoffice.gov.hk/eps/do/en/doc/Safety_Monitoring_of_COVID-19_Vaccines_in_Hong_Kong.pdf ).
A Government spokesman said, "Although the epidemic situation in Hong Kong remains stable and the figures of severe cases and deaths have not recorded a marked increase amid the emergence of new mutant strains, the community must continue to be vigilant. Deaths and severe cases involving children and elderly persons have been recorded in the fifth wave of the epidemic. For elderly persons, the COVID-19 vaccination rate for the elderly aged 80 or above in Hong Kong is only around 71 per cent at present, meaning that around 29 per cent of the elderly in that age group are in a dangerous situation, which is alarming.
"According to preliminary data analysis, out of the cases reported in the fifth wave, over 95 per cent of the fatal cases are elderly people aged 60 or above, with the proportion of death and hospitalised cases being the highest in those aged 80 or above. Most of the deceased cases are unvaccinated persons. As compared to the Hong Kong overall population, those who have received three doses of vaccine account for a much lower proportion among reported cases, and an extremely low proportion among the hospitalised critical/serious and deceased cases. This demonstrates the efficacy of three doses of vaccine in preventing infection, serious illness and fatality from COVID-19. The research data from the University of Hong Kong also shows that receiving three doses of either the Comirnaty or CoronaVac vaccine is highly effective in preventing severe cases and deaths with an efficacy of over 90 per cent. Members of the public who are currently eligible for a third dose should get the third dose as soon as possible.
"At present, persons aged 50 or above who had received three doses of vaccine may receive the fourth dose three months at minimum after the third dose. Children aged from 6 months to 3 years may also receive the CoronaVac vaccine. In addition to elderly persons, children are also our focus of protection in vaccination. We call on parents to arrange vaccination for their children as early as possible, thus enabling them to have early protection in the face of the threat posed by the highly transmissible mutant virus strains.
"In addition, the Government once again reminds members of the public that recovered persons who had been infected with COVID-19 should get vaccinated in a timely manner. For the Vaccine Pass, the recovery record QR code is valid within 180 days from the date of recovery. Recovered persons may need to receive one more dose of COVID-19 vaccine to comply with the Vaccine Pass, or update their vaccination records before the expiration of their recovery record QR code. Specifically, recovered persons who had not received any vaccine or had only received one dose of vaccine are required to receive an additional dose (first or second dose) of vaccine before their recovery record QR codes expire, in order to continue to use the Vaccine Pass. As for recovered persons who had received two or more doses of vaccine, they should update their vaccination records through the Electronic Vaccination and Testing Record System (www.evt.gov.hk), the 'iAM Smart' or 'eHealth' mobile applications before their recovery record QR codes expire, in order to continue to use the Vaccine Pass."
The spokesman also reminded that the vaccination requirements for persons aged 12 or above under the Vaccine Pass will be changed to having received three doses of vaccine starting November 30. Members of the public should receive the respective dosage of vaccine timely, such that they can get better protection for themselves and continue to use the Vaccine Pass for entering applicable premises.
