There were blatant efforts to mischaracterize people who were hospitalized for covid as unvaccinated, always, unless they were forced to classify them as vaccinated. That way they could say things like "90% of people hospitalized for covid are unvaccinated".
For instance, they would only regard them as vaccinated if they had actually been vaccinated that that particular hospital.
Otherwise they were classified as unvaccinated.
They had so many ways of twisting the data. We know they're liars and had a million ways to do that, to the extent that the full truth will never be known.
