The European Union's medicines regulator has recommended the Pfizer-BioNTech coronavirus vaccine for use in the bloc's 27 states. The European Medicines Agency (EMA) authorised the drug for the EU's nearly 448 million inhabitants after it went into circulation in the UK and the US. Hours after the EMA's decision, the European Commission gave its own formal approval for the use of the jab. Distribution could begin in some EU states as early as Sunday.
