Peter Doshi质疑的是疑似情况:
“Suspected covid-19”
All attention has focused on the dramatic efficacy results: Pfizer reported 170 PCR confirmed covid-19 cases, split 8 to 162 between vaccine and placebo groups. But these numbers were dwarfed by a category of disease called “suspected covid-19”—those with symptomatic covid-19 that were not PCR confirmed. According to FDA’s report on Pfizer’s vaccine, there were “3410 total cases of suspected, but unconfirmed covid-19 in the overall study population, 1594 occurred in the vaccine group vs. 1816 in the placebo group.”
打疫苗有疑似症状的比placebo多15%。这结果本身是不是有些意外?由于PCR测试有高达30%的假阴性所以Peter Doshi对结果有疑问。要求更多细节和raw data。
