COVID-19 Vaccines Adverse Events Response & Evaluation (CARE) Programme

COVID-19 is a global pandemic that affects people’s health and life. The COVID-19 vaccine is expected to play an important role in the control of the global pandemic. Hence, it is immensely important to closely monitor the safety of the vaccines as they begin to be taken up by the citizens of Hong Kong. A comprehensive post-marketing surveillance is needed to monitor for potential adverse events of COVID-19 vaccines while in widespread clinical use.

The CARE Programme is a comprehensive surveillance programme that closely monitor known and potential adverse events of COVID-19 vaccines. It aims to ascertain details of adverse events to inform the public in a timely manner. The HKU Department of Pharmacology and Pharmacy team is responsible for implementing the CARE Programme.

We are now inviting the COVID-19 vaccination priority groups to participate in our study. Your participation will allow researchers to build a better understanding of the vaccine, to promote and support future vaccination studies. We can work together to fight against the pandemic.




研究團隊誠邀首批優先接種2019冠狀病毒病疫苗的人士積極參與研究計劃, 協助研究團隊吸取經驗, 推展日後疫苗接種, 齊心打贏抗疫戰。

Purpose | 研究目的

This study aims to understand the potential adverse events seen in people of different age groups and their health statuses following COVID-19 vaccination. This study will be conducted in the form of follow-up surveys.


Content | 研究內容

Each vaccine recipient or caregiver will complete a set of online or paper survey 1,2,3,7, 14,28 day(s) after each COVID-19 vaccine injection (2 doses in total).

The surveys will record the health status and any adverse events seen in the vaccine recipient.

疫苗接種者或其照顧者在每次疫苗接種(共兩劑)後的第 1、2、3、7、14和28天,填寫最多12份電子或實體問卷。


Participation Eligibility | 參與者資格

You/Your ward will be eligible to participate in this study if you/your ward is a Hong Kong resident and have received COVID-19 vaccines.


Remuneration | 研究津貼

As a token of appreciation, each vaccine recipient/caregiver will receive a HK$50 gift voucher upon completion of all surveys for the 1st dose, and a HK$100 gift voucher upon completion of all surveys for the 2nd dose.


Data Collection | 個人資料收集

What kind of personal data is collected? 哪些個人資料將會被收集?

  • De-identified individual information, demographic information and vaccination records (such as vaccination date, type of vaccine, batch number and vaccination location).
  • 去識别化個人資料、人口統計學資料、以及疫苗接種紀錄(包括接種日期,疫苗類型、批號以及接種地點等)將會被收集。

What kind of clinical data is collected? 哪些臨床資料將會被收集?

  • Known and potential adverse events after receiving the COVID-19 vaccines and the relevant data such as diagnostic records and laboratory data from the hospitals will be collected.
  • 接種2019冠狀病毒病疫苗後已知及潛在的異常事件及其相關資料將會被收集,例如來自醫院的診斷紀錄和實驗室資料。

Why is such data collected? 收集上述資料的目的是什麼?

  • Your personal data will be collected to ascertain your COVID-19 vaccination status and your clinical data will be collected to investigate the association between any adverse events and the COVID-19 vaccines. It is immensely important to collect the data to conduct the surveillance to identify any adverse events following immunisation and inform the public in a timely manner.
  • 個人資料的收集是為了確定您2019冠狀病毒病疫苗的接種情況;臨床資料的收集則是為了確定接種2019冠狀病毒病疫苗後的異常事件的發生以及與疫苗接種的相關性。收集以上資料進行接種疫苗後的異常事件的監測並及時向社會公眾公佈至關重要。

How will the collected data be handled? 收集上述資料後將如何處理?

  • All data will be entered into electronic databases and destroyed as per usual practice after conclusion of the surveillance. All personal and clinical data will be anonymised and kept confidential. No personal identifier will be reported in the reporting of analysis.
