Study title: To compare the reactogenicity and immunogenicity of the 3 recommended COVID-19 vaccines in young adolescents in Hong Kong

The on-going COVID-19 pandemic has resulted in 100 million cases with over 2 million deaths globally. Prolonged school closure and isolation have generated adverse impact on school children. Moreover, children and adolescents under 20 years of age were more likely to infect others than adults older than 60 years. All COVID-19 vaccines approved for emergency use as of now have no published data for people younger than 16 years old.

This study by HKU Department of Paediatrics and Adolescent Medicine is targeted to recruit 300 healthy Form 1 to Form 4 students between 11-16 years old and their parent(s) will be offered to receive the same vaccine as the child. We will study the participants' adverse reactions (if any) and immune response to the vaccines.

研究項目:比較香港青少年人對三種2019冠狀病毒病疫苗的反應原性和免疫原性

2019冠狀病毒病大流行在全球造成超過1億宗病例,超過200萬人死亡,長時間的停課和社交隔離措施已對學生造成了不良的影響。 此外,20歲以下的兒童和青少年比60歲以上的成年人更具傳染性。 因此,為了減少家庭傳播並保護老年人免受2019冠狀病毒病的感染,我們建議給兒童和青少年接種 2019冠狀病疫苗毒病疫苗。截至目前,所有已批准作緊急使用的2019冠狀病毒病疫苗都仍未有針對16歲以下人群的公開數據, 因此,現在正積極倡導並進行在兒科的研究。這讓公眾可以更暸解2019冠狀病毒病疫苗在兒童的效能及安全性,並為整個群體的疫苗接種鋪路。

這項研究由港大醫學院兒童及青少年科學系負責,目的是招募300名11至16歲健康的中一至中四學生,同時也為每位招募的學生的父母接種與孩子相同的疫苗。我們會研究參加者對疫苗的不良反應(如有)和免疫反應。
