In a significant development Friday, the Food and Drug Administration (FDA) asked Johnson & Johnson to discard 60 million doses of its coronavirus vaccine manufactured at the Baltimore plant in the United States.
This brings the total number of discarded doses of Johnson & Johnson to 75 million.
The fate of more than 100 million other doses of Johnson & Johnson and AstraZeneca vaccines is yet to be decided.
All these doses were manufactured at the Baltimore plant of Emergent BioSolutions.
The Baltimore plant of Emergent BioSolutions has been under investigation since March this year when the authorities found evidence of possible contamination at the site.
The plant has been shut down since.
The 21 million doses of the Johnson & Johnson coronavirus vaccine, which has been used in the United States, were manufactured in the Netherlands.
Earlier, Johnson & Johnson vaccine had come under scrutiny for possible link to a blood clotting disorder.
Johnson & Johnson vaccine was considered promising as it’s single shot vaccine, compared to other vaccines whose two doses are required.
