America’s COVID vaccine rollout has been far from perfect, but four months in—with three authorized vaccines available to an ever-widening share of the population, at settings ranging from retail pharmacies to health providers to mass vaccination sites—it’s going pretty well.
As of Wednesday, April 7, 110 million Americans—roughly a third of the population, and 42.4% of adults, had received at least one dose of a COVID vaccine, according to data from the Centers for Disease Control and Prevention. That number is up from 97.6 million people last Wednesday; on average, the U.S. administered more than 3 million doses daily in the past week.
Nearly a quarter of all adults, a total of 64.3 million, and 57.4% of Americans over the age of 65, have been fully vaccinated. The vast majority of vaccinated individuals received one of the two-dose Pfizer or Moderna mRNA vaccines; about 4.5 million Americans have received the one-shot product developed by Johnson & Johnson.
In terms of states, New Hampshire has vaccinated the largest share of its population—43.6% of its residents have received at least one dose, according to CDC data; New Mexico has reached 41.4%. California, the nation’s most populous state, has administered 20.9 million vaccines and reached 35.1% of the population with one dose. Alabama and Mississippi, each of which has reached 26.3% of their residents with a coronavirus vaccine, have the lowest percentages.
While the U.S. rollout has picked up pace, efforts in Europe have been troubled this week by another revelation regarding the AstraZeneca COVID vaccine. European regulators on Wednesday said that while the vaccine is “probably the cause” of extremely rare blood-clotting incidents, the benefits of the vaccine’s use outweigh the risks. Production and supply issues are challenging the rollout elsewhere around the world.
