The European Medicines Agency (EMA) has said it is aware of a contaminated batch of the active substance used to make Johnson & Johnson’s Covid-19 vaccine and that they’re taking precautionary action to prevent possible harm.

In a press release on Friday, the EMA said contamination had occurred at a manufacturing site for the active substance in Maryland, US. While the contaminated batch was not intended for the EU market, other batches of the active substance made in the same facilities were intended for the 27-nation bloc. (RT)
