Politico: “After a week on the job, Biden’s team is still trying to locate upwards of 20 million vaccine doses that have been sent to states – a mystery that has hampered plans to speed up the national vaccination effort. Only a small percentage of those unaccounted for doses – roughly 2 million, two officials said – is due to lags in data reporting, the Biden team believes. That would mean the rest of the crucial supply is boxed away in warehouses, sitting idle in freezers or floating elsewhere in the complex distribution pipeline that runs from the administration to individual states. That’s a dilemma that predated the Biden team’s arrival, with Biden himself hammering the vaccine rollout’s first weeks under the Trump administration as a ‘dismal failure.’ Yet the response team underestimated at the outset how difficult it would be to fix.”
