And, likewise, you cannot NOT attribute them to the vaccine.
Inconclusive data is not to be either used as a calibrated measure nor to be simply ignored.
The excess deaths are quite possibly attributable to both the virus and the vaccines if, as one plausible but very unproven example, they're due to inflammation and/or micro-clotting caused by the spike protein. But in an environment where everyone will be exposed to the actual virus eventually, with uncontrolled initial exposures, it comes down to whether the benefit of getting vaccinated is worth the risk. The data I've seen says that it is.
