That’s out of context, the VP said she would take a Vaccine endorsed by medical professional not the president. It was and attack on Trumps trying to reduce red tape / rush things depending on perspective, not any specific or hypothetical vaccine.
It’s perfectly reasonable to agree or disagree with rushing vaccine deployment even further, but don’t attack a straw man.
Up until December we had the Pres/VP candidates saying they would not take any vaccine that Trump endorsed. Then they won, and were faced with convincing everyone to take those very vaccines. Do you believe them now, or then?
