These are the vaccines that the UK has secured:
Oxford-AstraZeneca – 100 million doses
Valneva – 60 million doses
Novavax – 60 million doses
GlaxoSmithKline – 60 million doses
Pfizer-BioNTech – 40 million doses Janssen – 30 million doses
Moderna – 17 million doses
Three have been approved, Astra Zeneca, Pfizer and Moderna. A total of 157million doses. This alone is sufficient to give 2 doses to every single member of the UK jpopulation. (UK pop. is Just under 70 million)
Then there are another theoretical 180 million doses available if the remaining vaccines are approved. Enough to double dose the whole population again, with a few million to spare.
It looks as though we are in a good position to share with with other countries.
Or am I missing something?
(And no, I don't expect them to all be available at once, I realise that there is a time element in manufacturing them)
And, it should be noted that A16 was not invoked.
