It probably doesn't mean much. The Vaccine can sit in a freezer for a good old while and it just means the EU will get their X million in a slightly bigger lump.According to Worldometer, c. 100k new cases of CV yesterday (not including the UK).
Would it not be a good time for the 27 to break ranks, and expedite authorisation of a vaccine?
Or, is a united front preferable?
A few days earlier is nice, but anything that looks like rushing something through without full testing is Anti-vaxxer cocaine. They do not deserve cocaine and are not pleasant if they get it.
