Around 4 million Americans received the updated COVID-19 shots in September, according to the U.S. Department of Health and Human Services (HHS), even as some people have found it difficult to book vaccination appointments or find the vaccines at no cost.
“The Biden-Harris Administration, through HHS, has been working directly with manufacturers and distributors to ensure that the vaccines are getting to pharmacies, hospitals, clinics, and other vaccination sites, including long-term care facilities as quickly as possible,” a spokesperson for the department said in an emailed statement.
