It's absolutely true no matter how many times you say otherwise. Their "plan" was exceedingly simple...let the states handle it. They co-ordinated nothing.
"The process to distribute the vaccine, particularly outside of nursing homes and hospitals out into the community as a whole, did not really exist when we came into the White House."
Politifact rated this mostly false based on this:

rely on the states. (emphasis mine)
Now, where I come from, saying "YOU come up with a plan" isn't really a plan. Maybe it's different in your part of the world.
