部分錯誤。影片中的講者為克羅埃西亞歐洲議會議員Mislav Kolakušić,其對於英國疫苗數據的解讀,含有錯誤資訊,但指稱輝瑞因沒有提出防止人際傳播的疫苗數據,應該返還預算等內容,則為個人意見。

1. 英國國家統計局(ONS)數據及衛生安全局(UKHSA)對疫苗有效性的監測,已顯示接種COVID-19疫苗能降低重症與死亡率。
根據英國確診死亡與接種狀態的分析,各年齡層中,接種三劑疫苗的死亡率確實低於未接種或接種兩劑以下者。研究也指出,輝瑞加強劑對於重症、住院能提供97%至99%的保護力。影片提及英國相關數據「完全不因接種疫苗有所差別」,為錯誤資訊。

2. 輝瑞國際市場總裁Janine Small確實表示,疫苗上市前未研究其是否能阻止病毒傳播,但疫苗臨床測試的用意,本來就只在於確認預防疾病與重症的功效,而非「阻止傳播」。Kolakušić認為歐盟應終止合約、輝瑞應返還預算等內容,僅為個人意見。

(1)埃默里大學疫苗中心副主任Walter Orenstein博士表示,「傳播」是複雜的衡量指標,輝瑞在臨床試驗期間沒有研究疫苗對傳播的影響並非特例。

(2)輝瑞自始沒有聲稱病毒能阻止傳播。美國FDA於2020年12月11日通過疫苗授權的新聞稿,也明白表示「目前,沒有數據可以確定疫苗將提供多長時間的保護,也沒有證據表明該疫苗可防止SARS-CoV-2在人與人之間傳播。」

(3) 費城兒童醫院疫苗教育中心主任Paul Offit指出:「當你接種疫苗,將明顯降低你被感染的機率,因此也會降低你將其傳播給他人的機會」,雖不能保證消除所有的傳播,但疫苗上市後的研究確實發現,輝瑞疫苗有助於減少alpha和delta變種的傳播。
