Cases of “SARS-CoV2 infection” refer to the same vaccinated population.
Dear Editor,
the article by Hippisley-Cox et al. states that the cases of “SARS-CoV2 infection” refer to the same vaccinated population. Cf. ibd.
“We also investigated the association between a SARS-CoV-2 positive test and the thrombotic events of interest among the same vaccinated population.”
and
“Table 1: Baseline demographic characteristics of people receiving first dose of covid-19 vaccine or testing positive for SARS-CoV-2 virus among vaccinated population in England from 1 December 2020 to 24 April 2021”

The same can be read on the picture on Dr. Hippisley-Cox’s twitter account, “...who went on to catch COVID-19”, see https://twitter.com/JuliaHCox/status/1431141982555058176
As I read it the “SARS-CoV2 infection” cases were vaccinated. Hippisley-Cox et al. should clarify this point.
Best regards,
