Also there are two other things with the pfizer

1, People with allergies having the Pfizer vaccine (they say you can now have it but will put people off I know it has me, would need a detailed convo with GP & you know what I think of them!)

2, The UK not giving the second vaccine three weeks later leaving it three months later when Pfizer it's self has said they have no clue if it will still give protection with that distance between doses, where the Oxford one has been in trial tested to be safe & gives higher protection at 3 months between doses.

So some people will turn it down & wait for the Oxford one
