According to Kate Riga and Josh Kovensky of Talking Points Memo, Trump’s Health and Human Services Secretary Azar gave “health officials the impression that their stockpiles would grow and allow them to dramatically expand the vaccination effort. “

“That promise turned out to be entirely hollow — there was no such reserve, as the administration had already been shipping out all the vaccine available, taking second doses right off the manufacturing line.”

That’s what Biden meant when he said there was no vaccine when he took office. Trump had NO RESERVES.  He’d depleted the reserves; leaving Biden with nothing to work with.
