Just thought I would update on the advice which I have just got from my NHS consultant at Royal Marsden.
His view is that both Pfizer and Moderna are suitable and that the Astra Zeneca (Oxford) vaccine will also be suitable after it receives it's UK license .
He also felt it would be advisable to accept whichever vaccine of the 3 is offered first. (which is what he will be doing personally !)
I plan to follow his advice.
