No, people died because REPUBLICANS played politics with people's lives and told them the vaccines were "experimental" and people were dying from taking the vaccines. Neither of these things were true.
Democrats weren't in office in 2020, and by the time Biden was inaugurated, over 10 million Americans were sick with covid and the disease was mutating rapidly. At the then-current rate of death, approximately 200,000 of those sick on Inauguration Day, would die, taking Trump's death toll up to 700,000 and reducing Biden's numbers to 300,000. That's less than half of those who died in under the Trump Administration's handling of the crisis.
Dr. Faucci had warned early in the pandemic that if they did nothing to stop the spread, over a million Americans would die before you achieved Herd Immunity, and the vaccines would never end it. And THAT is what happened when Trump decided to go for "herd immunity" because it meant he did nothing.
There was no coming back from that much infection being allowed to run wild.
