If the Oxford vaccine proves effective, we will have enough vaccine for the whole of the UK (that's what I've read). If reliant on the other 2 front runner vaccines the limit is for 20 million.

But the US FDA is requiring a 3 month booster is administered, with subsequent monitoring, before it will approve any vaccine at the moment
