Millions of Covid-19 vaccines are sitting unused in US hospitals and elsewhere a week into the massive inoculation campaign, putting the government’s target for 20 million vaccinations this month in doubt.

As of Wednesday morning, only 1 million shots of the Pfizer-BioNTech vaccine had been given, about one-third of the first shipment sent last week.

Over 9.5 million doses of vaccines, including Moderna’s, have now been sent to states, according to the US Centers for Disease Control and Prevention.

While hospitals have started giving out Moderna’s vaccine, the CDC has not yet reported that data and there may be a lag in reporting shots given of both the Pfizer and Moderna vaccines.
