Yeah, funny. But I get mainly pseudoscience results for the first link anyway. I had already since found the precisionvaccinations site (not a pseudoscience source), which simply reports the numbers, and also clearly states that the reported figures are not indications that the vaccines caused the deaths. It makes no claim that anything underhanded happened, and certainly makes no claim that 'the Biden admin' made the change. The different figures are consistent with the scenario I postulated about a database error (though that is not necessarily the reason).

Your second site is a known pseudoscience source.
