The European Union has bought an additional 100 million doses of the Pfizer/BioNTech vaccine — bringing its total to 300 million, European Commission President Ursula von der Leyen tweeted Tuesday.
"More vaccines will follow," von der Leyen added.
The EU officially kicked off its Covid-19 vaccination campaign on Sunday, days after approving the Pfizer/BioNTech coronavirus vaccine on Dec. 21.
The vaccine rollout comes as European governments race to contain the spread of a new Covid-19 variant that was first detected in the UK.
The European Medicines Agency (EMA) is continuing its rolling review of other promising vaccine candidates, including those from AstraZeneca and Oxford University, and Johnson & Johnson.
