AIUI, over the past week the USA has averaged 1.25 million doses administered per day.
But yesterday there were 1.6 million doses administered.
Also, yesterday the doses were about evenly split between first dose and second dose, which is I guess exactly as it should be once the large scale rollouts are all underway.
Meanwhile, here in California, the state is administering just under 200,000 doses a day, and today it should surpass 8 million doses administered, which means (more or less) that 10% of the state's population has been vaccinated.
That's still agonizingly slow; somehow the state has to get much closer to 500,000 doses a day, and soon.
Before it's too late (if it isn't already).
500,000 doses a day would still mean six more months to vaccinate the state.
