最近多個國家都著手研究新冠肺炎,而近日英國牛津大學與阿斯利康(AstraZeneca)合作研發的疫苗有效率達70%。而有外國媒體報導指,採用特別的注射疫苗方法更可將防護率升至90%。

英國牛津大學與製藥公司阿斯利康(AstraZeneca)合作研發出新冠肺炎疫苗,測試結果表示疫苗平均防護率為70%。但另有研究指出,若調整注射疫苗的劑量,先注射半劑,再注射一劑,可令疫苗有效率升至90%。

該疫苗測試召集了來自英國和巴西約2萬多名志願者參與,其中有30名感染者接種兩劑疫苗,101名感染者接受虛擬注射。測試結果顯示,接種兩劑全劑疫苗防護率為62%。但若接種半劑後,再注射全劑,防護率可高達90%。

據BBC報導指,英國政府已向牛津預購一億支疫苗。而疫苗研發商阿斯康利製藥則表示,明年將為全球供應30億劑疫苗。
