Isnt this just explaining scientifically that confirmation bias exists?Only 27 people in the total sample (a subset of which had prior infection). So we are dividing a subset of 27 into at least 2 groups (those who had Covid with little or mild symptoms and those who had stronger symptoms).
From the study:
Participants who were seropositive (n = 13) and seronegative (n = 14) prior to vaccination were included. Four seropositive individuals had PCR confirmed COVID-19 infections; remaining seropositive individuals had asymptomatic cases.
They use confirmed PCR test as a proxy for severity of symptoms.
It seems the conclusion is that the vax illicits a stronger immune response for those who had symptomatic cases of Covid rather than concluding that having a mild case doesn't provide immunity.
"we find stronger vaccine responses following prior PCR-positive SARS-CoV-2 infection. Importantly, these stronger responses were limited to participants with PCR confirmed cases of COVID-19, and were not seen among those who did not experience symptoms or were seronegative."
They were looking for stronger responses amongst those with worse symptoms. And found it. And then used that stronger response to justify that the vaccine works, while not at all showing an actual link between vaccine and actual effects vs Covid.
I may be getting lost in the text and numbers but the more I read the less I understand what they were actually doing.
