From Fast Company‘s Michael Grothaus: “Operation Warp Speed is sputtering. Under the Trump administration’s vaccination roll-out, the goal was to have 20 million Americans receive their first dose of the COVID-19 vaccine by the end of December — a critical step in not only inoculating the most vulnerable, but also eventually achieving herd immunity in the country

“It is estimated that between 80% and 90% of Americans would need to be vaccinated to reach herd immunity.

“But instead of 20 million doses being administered this month, the U.S. has only administered 2.1 million doses so far — barely a tenth of the original goal, reports Axios. That means that if the U.S. is to meet its 20 million goal, it would need to vaccinate more than five million people a day between now and the end of Thursday — an unlikely occurence.”
