The Food and Drug Administration, which found unsanitary conditions in an inspection of the plant in April, cleared 10 million doses made at the facility for use. Those salvaged doses are expected to be sent overseas as part of President Biden’s effort to share vaccines with other nations.

The plant fell under federal scrutiny after a discovery in March that a batch of Johnson & Johnson’s vaccine was contaminated with a key ingredient used to produce AstraZeneca’s.

The 60 million doses that must be discarded are in addition to the 15 million already thrown out that were contaminated by the AstraZeneca vaccine at the plant this year.
