A request for Emergency Use Authorization in the US was submitted the same month; and the vaccine was then authorized in the US on December 11 (shortly after UK authorization on December 2).
The trial is not over, however: as all subjects are monitored for a further two year period. And the next step is to test the vaccine in groups that cannot currently receive the vaccine due to a lack of data – such as pregnant women and children (Pfizer has already started a trial in pregnant women and one in children is set to follow later this year).
