The release of the COVID-19 vaccine produced by Pfizer and BioNTech is still a long way off, but humanity is already inspired and ready to buy the novelty in huge quantities. The European Commission reported on the conclusion of a deal for the supply of 300 million doses of vaccine. Great Britain will buy another 40 million.
Pfizer said Monday that the coronavirus vaccine it is developing with BioNTech has shown 90% efficacy in Phase III clinical trials. Note that so far this is the only vaccine that has passed the third stage of testing, during which the ability of the drug to prevent infection is assessed.
There are currently around 70 COVID-19 vaccines in development worldwide. None of them have been approved for full-scale use yet.
