According to Table 2 their sample had 8,199 unvaccinated and 9,269 vaccinated. It seems odd that more cases were found in the vaccinated people, can anyone suggest why? Statistical anomaly?
Edit: I misread the table, I thought column 1 was number of subjects. The replies explain well why the # of cases would be larger for the (larger) vaccinated population.
