ChAdOx1nCoV-19 vaccination

ChAd0x1 nCoV-19 (AZD 1222) is the main vaccine that is planned to roll-out in Thailand and involve vaccinating people especially in high-risk categories. This vaccine is contained in the multiple-dose vial for vaccinating 10 recipients for 0.5 mL each. However, the additional volume of vaccine was overfilled to 6.5 mL per vial which the vaccination can be administered to more than 10 doses. The University Hospital Network (UHOSNET) and Faculty of Medicine Vajira Hospital, Navamindradhiraj University have jointly stipulated the preparation and vaccination of ChAdox1 – n CoV-19 vaccine with 12 doses per vial injection with traditional 21 or 24 G needle. Taken together, we planned to investigate the immune response of participants after first dose of ChAd0x1 nCoV-19 vaccination with such technique

ChAd0x1 nCoV-19（AZD 1222）系泰国计划推广的主要疫苗，旨在为高风险人群接种疫苗。该疫苗封装于多剂量安瓿瓶中，每瓶可供10人接种，每人剂量为0.5毫升。然而，疫苗的额外容积超量填充至每瓶6.5毫升，使得每瓶疫苗可用于超过10剂次的接种。由大学医院网络（UHOSNET）和瓦吉拉医学学院Vajira医院、纳瓦米德拉德哈大学联合规定，ChAdox1-n CoV-19疫苗的制备和接种应采用每瓶12剂次的注射方式，并使用传统的21或24G针头。综合而言，我们计划采用此技术，研究ChAd0x1 nCoV-19疫苗接种第一剂后参与者的免疫反应。
