高端 採用的就是美國 FDA 要求的第三期條件去做 第二期 https://www.fda.gov/media/142749/download Emergency Use Authorization for Vaccines to Prevent COVID-19 Guidance for Industry Document issued on May 25, 2021. 這是 FDA 準則 建議的 第三期標準 以美國FDA的標準 , 申請EUA提交的文件包括該疫苗進行的第1階段和第2階段研究積累的所有安全性數據,並希望第3階段數據包括至少平均有 2個月的追蹤follow-up(這意味著在完成完整的疫苗接種方案後,至少有一半的3期臨床試驗疫苗接受者有2個月的追蹤查訪。) 美國 FDA 對於第三期 數據的標準是 超過 3,000 名疫苗注射受測者
高端 的第一期 報告 期刊上就有MVCCOV1901數字, 公開在Lancet 集團 出版的期刊上 E Clinical Medicine (Published by THE LANCET) Safety and immunogenicity of a Recombinant Stabilized Prefusion SARS-CoV-2 Spike Protein Vaccine (MVCCOV1901) Adjuvanted with CpG 1018 and Aluminum Hydroxide in healthy adults: A Phase 1, dose-escalation study https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(21)00269-8/fulltext Published:June 25, 2021DOI:https://doi.org/10.1016/j.eclinm.2021.100989

FDA的EUA不要只說一半喔 對efficacy 的要求 FDA acknowledges the potential to request an EUA for a COVID-19 vaccine based on an interim analysis of a clinical endpoint from a Phase 3 efficacy study. Issuance of an EUA requires a determination that the known and potential benefits of the vaccine outweigh the known and potential risks. For a preventive COVID19 vaccine to be potentially administered to millions of individuals, including healthy individuals, data adequate to inform an assessment of the vaccine’s benefits and risks and support issuance of an EUA would include not only meeting the prespecified success criteria for the study’s primary efficacy endpoint as described in the guidance for industry entitled “Development and Licensure of Vaccines to Prevent COVID-19” (Ref. 1) (i.e., a point estimate for a placebo controlled efficacy trial of at least 50%, with a lower bound of the appropriately alpha-adjusted confidence interval around the primary efficacy endpoint point estimate of >30%), but also additional safety and effectiveness data as described below in this section. The timing of interim analyses planned for a Phase 3 study would thus ideally be aligned with the ability of the analyses to meet these criteria. =============== 用的是預防感染至少50趴,不是用效價比較,也不是預防重症死亡啦
