In a week which America is blowing past cheering pandemic milestones—reaching 150 million vaccines administered (yesterday); 100 million people vaccinated (likely today)— the country nonetheless finds itself in an awkward spot: New coronavirus cases are ticking up across the country, in part because of the spread of more contagious COVID variants. Rochelle Walensky, the Director of the Centers for Disease Control and Prevention (CDC), confessed to feeling a sense of “impending doom” on Monday. Are we on the verge of a fourth surge?
Those very real concerns can be hard to square with the end-of-the-tunnel euphoria being felt across the country as the COVID vaccine rollout progresses, and more and more states extend eligibility to the general public. On Monday, President Joe Biden said 90% of the U.S. adult population would be eligible for the vaccine in a matter of weeks, by April 19. He also encouraged states to reinstate mask mandates and for the public to keep up COVID-safe protocols.

As of March 31, 97.6 million Americans—29.4% of the total population, and 37.7% of adults—had received at least one dose of a COVID vaccine, up from 85.5 million a week ago, according to data from the CDC. Roughly 54.6 million have been fully vaccinated. Numbers for the more vulnerable senior population are especially impressive: 73.5% of Americans 65 and older have received at least one dose, and just over half have been fully vaccinated. The nation has administered 150.3 million doses of the 195.6 distributed across the country.
Across the states, the share of residents who have received at least one dose of the vaccine vary considerably, from 23.6% in Alabama to 38.1% in New Mexico. In California, the nation’s most populous state, 30.7% of the population has received at least one dose of the vaccine. In total, the state has administered 18.2 million vaccines.

The vast majority of coronavirus vaccines administered across the country are the two-dose products developed by Pfizer and Moderna; about 3.3 million Americans have received the one-dose shot from Johnson & Johnson.
