Moderna has supplied 45.5 million doses of Covid-19 vaccine to the United States, the company announced Tuesday.
The company said data from the US Centers for Disease Control and Prevention shows about 25.5 million doses of its vaccine have been administered across the nation.
An additional 33.2 million doses have been filled into vials and are going through final production and testing before being released to the government, according to the company's latest supply update.
Some of the doses have not been released due to delays.
"Short term delays in the final stages of production and release of filled vials at Moderna’s fill and finish contractor Catalent have recently delayed the release of some doses, but these delays are expected to be resolved in the near term and are not expected to impact monthly delivery targets," the company said in a press release.
Moderna said it expects to deliver 100 million doses by the end of March, followed by an additional 100 million doses by the end of May and another 100 million doses by the end of July.
