この話はファイザーワクチンの臨床試験の有効性は相対リスクだと95%減少(プラセボ162人→ワクチン8人)だが絶対リスクだと解析者約18000人の参加者中154人(0.85%)しか減っていないという話ですが↓ https://www.reuters.com/article/factcheck-thelancet-riskreduction/fact-check-why-relative-risk-reduction-not-absolute-risk-reduction-is-most-often-used-in-calculating-vaccine-efficacy-idUSL2N2NK1XA/ プラセボも162人しか発症してないというのは「流行が下火の20年秋の試験中の中央値2か月間」の話で↓ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9115787/ 米国なら接種完了後に日常に戻る中、接種があっても新型コロナには3分の1の現役世代が21年秋には毒性の高い株での感染抗体を保持しており↓ https://www.cdc.gov/mmwr/volumes/71/wr/mm7117e3.htm#F1_down 接種してもしなくても99%の人の帰結には差がない様な示唆こそ米国では誤謬だった事は言うまでもありません
