Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Our findings are subject to a few limitations. First, we were not able to take into account immune status before hospitalization because serology was not consistently performed at admission, and prior SARS-CoV-2 infection was not consistently reported. This might have underestimated our VE-estimates. Second, our results are not representative for the VE against the delta variant, affecting the generalizability in the current epidemiologic situation. However, recent studies suggest that the VE against hospitalization is also very high in settings with dominance of the delta variant (10, 20). Third, most patients were only partially vaccinated. Therefore, our study was underpowered to measure the effect of full vaccination in many subgroups. Fourth, it was not feasible to only include patients admitted because of suspected COVID-19 because SARS-CoV-2 PCR at admission is not reserved for patients suspected of a respiratory infection. Residual bias due to health-seeking behavior otherwise mitigated by the test negative design might therefore still exist. Based on the patient characteristics we suspect the control group to consist partially of chronically ill patients admitted for an acute deterioration of their respiratory or cardiac condition. This might have underestimated the VE since the sensitivity analysis showed higher VE estimates in a more infection-specific subgroup. Fifth, residual confounding due to unmeasured factors such as ethnicity might have biased our estimates....
