Remember, the "slow" roll-out of the vaccine is all Trump's fault -- never mind that without Trump, we probably would have had no vaccine to distribute in less than 18 months.
12.5M doses of the estimated 20M have been distributed to the states. Of that, only 3M have been administered. Again: all Trump's fault.
Fauci estimated we'd have herd immunity at 50%, then 60%, then 70%, then 80% -- but he's allowed, since this stuff is "new" and all. But, when Trump reports an estimate of doses to be distributed to the states -- an estimate provided by the manufacturers -- it's just one more mark in his "he fumbled the COVID-19 football" scorecard yet again.
Now we have a doctor tampering with the vaccines -- about 500 doses -- which makes the injection ineffective (CDC says no negative effects were reported or are expected, but no details reported on what the tampering entailed). Once again, this was all avoidable if Trump hadn't been so incompetent.
Weather, holidays and other "life" factors have been hindering distribution on many regions -- all because of Trump.
I fully expect a President Biden will be blaming Trump still for any and every problem that arises the next 4 years, just like Obama blamed Bush for 8 years. That is, assuming the Press even bothers to let the public know about any problems (just like Obama's scandal-free presidency).
