EU plans to buy up to 300 million doses of Pfizer-BioNTech vaccine

The European Commission will sign a deal to secure up to 300 million doses of the experimental coronavirus vaccine developed by BioNTech and Pfizer.

Ursula von der Leyen, the president of the EU's executive arm, said the commission will authorize the deal on Wednesday after working tirelessly to secure doses of potential vaccines in recent months.

This is the most promising vaccine so far, von der Leyen said. Once this vaccine becomes available, our plan is to deploy it quickly, everywhere in Europe. Pfizer said Monday that early results from the vaccine suggests the shots may be a surprisingly robust 90% effective
