And for every single study of every single variant that has been studied, the vaccine in the study significantly reduces the incidence of severe cases of COVID-19 among the trial group. There is not a single study covering any variant for which this is not the case.

Yes we have obviously not tested every combination of vaccine and SARS-CoV-2 variant. But so far, the evidence that we have supports the working assumption that all vaccines drastically reduce, or in some cases eliminate entirely severe COVID-19 symptoms.
