Combination of mRNA and inactivated COVID-19 vaccines: A prospective cohort study
Combination of mRNA (Comiranty) and inactivated (CoronaVac) COVID-19 vaccination might improve the vaccine immunogenicity and safety when compare to vaccination with two doses of the same type of vaccine.
This study by HKU Department of Medicine targets to recruit 150 adult subjects 18 years or above and randomise to receive a single dose of of Comirnaty followed by a single dose of CoronaVac, or two doses of Comirnaty or two doses of CoronaVac. Subjects will be follow-up and assessed for a total of 1 year for vaccine immunogenicity and safety.
接種mRNA和滅活的2019冠狀病毒病疫苗的混合組合：一項前瞻性群組研究
與接種兩劑同一類型同一劑量的疫苗相比，mRNA（復必泰）和滅活（克爾來福）2019冠狀病毒病疫苗的聯合使用或可提高疫苗的免疫完成和安全性。
這項港大醫學院內科學系的研究，目的是招募150名18歲或以上的成年人士，並隨機接受單劑量的復必泰疫苗，然後接受單劑量的克爾來福疫苗，與接受兩劑復必泰疫苖或兩劑克爾來福疫苗作比較。我們對受試者進行為期一年的疫苗免疫性和安全性跟進。
Content | 研究內容
The aim of this study is to investigate the immunogenicity profile of people getting vaccinated.
Volunteers will be required to:
- Perform screening procedure by completing a simple health assessment
- Sign a consent and take blood and saliva tests for antibodies before proceeding to vaccination
- Join a total of five blood and saliva tests:
- The day of 1st dose of vaccine
- The day of the 2nd dose of vaccine
- Four weeks after the 2nd dose of vaccine
- Half a year after the 1st dose of vaccine
- One year after the 1st dose of vaccine
此項研究的目的是獲取不同疫苗在人體內的免疫反應數據。
我們將：
- 為參與者進行簡單的健康評估
- 如符合資格，參與者在簽下同意書後，將安排抽血及採集口水樣本測試抗體，再進行疫苖注射
- 第一次注射疫苗及第二次注射疫苗，參與者需要填寫注射疫苗日記，以監察疫苗的副作用。我們會跟進及監察參與者對疫苗的反應及免疫力數據。
- 我們會為參與者抽血及採集口水樣本，總共五次：
- 注射第一劑疫苗當天
- 注射第二劑疫苗當天
- 注射第二劑疫苗之後的四個星期
- 注射第一劑疫苗的半年後
- 注射第一劑疫苗的一年後
Venue | 研究地點
The research will be carried out at the Community Vaccination Centre in Ap Lei Chau Sports Centre.
研究將在鴨脷洲體育館社區疫苗接種中心進行進行。
