Evaluating Population Immunity against COVID-19 and Other Respiratory Virus Infections (EPI-HK Study)
The research team at the HKU School of Public Health have been at the forefront of research into COVID-19. One major question is “how many people have been infected so far”. The HKU team are part of a large consortium of international experts to answer this question in different parts of the world.
In Hong Kong, we sincerely invite all Hong Kong residents of all ages to join our study, so that we can collect blood samples to look for evidence of infection with COVID-19 as well as other respiratory viruses such as influenza in the community. In addition to determining the frequency of infection, we will also be able to determine how long immunity will last after infection and vaccination. To achieve this, we will regularly monitor the health conditions of our study participants through questionnaires, blood draws and respiratory sample collection. When participants report acute respiratory symptoms, we will collect additional respiratory samples.
To show our appreciation of the participant’s support, we will provide study participants with basic body check, supermarket coupons and free influenza rapid test.
You are eligible to join the study if you meet the following requirements:
No cost will be incurred for joining this study. To appreciate your time spent and support for our study, for each visit for blood draw and respiratory samples collection during the regular follow-up every 6 months, you will receive supermarket coupon valued at HK$100; and if you agree to provide additional blood or stool samples, you will receive an additional supermarket coupon valued at HK$50.
Upon the report of an eligible respiratory illness, for each visit with respiratory samples collection, you will receive supermarket coupon valued at HK$50; and if you agree to provide additional blood samples, you will receive an additional supermarket coupon valued at HK$50.
In addition, you will receive a complementary influenza rapid test in the first visit for each eligible respiratory illness. If you have completed the follow-up study activities in a year, we will offer you a basic body check service.
