Do we really have a vaccine?
Pfizer Inc. and BioNTech SE have announced preliminary results of a new COVID-19 RNA vaccine which has been shown to give 90% protection seven days after the second dose. It is believed that, if approved, 50m doses could be ready by the end of the year and an additional 1.3bn by the end of 2021.
