Over 38m Americans received at least one Covid-19 vaccine dose, but states face supply shortages

Across the United States, 38 million people have received at least one dose of a Covid-19 vaccine, though many states face vaccination supply shortages.
"The vaccine supply coming to San Francisco's healthcare providers and the Department of Public Health (DPH) is limited, inconsistent, and unpredictable, making vaccine roll out difficult and denying San Franciscans this potentially life-saving intervention," officials reported Sunday. "The City has the capacity to administer more than 10,000 vaccines per day but lack the vaccine supply."
