A Baltimore factory that botched the production of 15 million doses of the Johnson & Johnson Covid-19 vaccine hasn't been able to distribute any of its doses because of a certification issue, according to The New York Times.

The factory for Emergent BioSolutions, a biotech firm that's known for producing anthrax vaccines, has produced at least 150 million Johnson & Johnson vaccine doses — none of which have been used, The Times reported.

The manufacturng plant ruined 15 million vaccine doses last month of the Johnson & Johnson vaccine when an employee reportedly mixed up vaccine ingredients.

The mistake came only a month after the vaccine had gained authorization in the US. At the time, the company said it planned to deliver 100 million doses by the end of June and 1 billion within the year.
