Pfizer booster safe if originally had Oxford AZ?

[Liamo]

Found this on BBC which still manages to avoid answering my question (and the one asked), and how do they know who is allergic to mRNA vaccines?

They only know that you're allergic if you've had a previous allergic reaction.

"You will be offered the right vaccine for YOU which may be the same or different from the vaccines that you had before". So the right vaccine for EVERYONE in Glossop is Pfizer irrespective of which vaccine they had previously, doesn't ring true does it?

I see this has now been amended to read "You will be given a booster dose of either Pfizer or Moderna vaccine" with a footnote that "AstraZeneca may be an option if this is the vaccine that you had for the first 2 doses." I'd like to know why they say "may be an option", they never explain things fully

It was said that it may be an option if there wasn't enough mRNA vaccines at individual vaccination sites. A fallback situation.
