Pfizer reported 170 PCR confirmed COVID-19 cases, split 8 to 162 between vaccine and placebo groups. I have as well looked at the data and to me, these numbers are 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 of Pfizer's vaccine, there were 3410 total cases of suspected, but unconfirmed COVID-19 in the overall study population. Does that seem dwarfed to you? Why did they have this large group of suspected but unconfirmed?
