Which vaccine should I choose?

[Serendipity09]

I have just been sent the link for my Covid vaccine, I'm 44 but have underlying health problems and am a carer.
I wasn't expecting to be given the choice about which vaccine to choose before I book!
So now I have no idea....initially I was all for the more natural Oxford vaccine as opposed to the synthetically made Pfizer vaccine, but now studies seem to show that Pfizer is more effective?
I do have allergies, not severe, but moderate I would say - although that doesn't seem to be so much of a worry with Pfizer now?
I really didn't mind which one I was having, just felt pleased to be having it, but now I've been given the choice, I feel anxious about it!!
Any wise words please?

Which data? The studies linked in the FT earlier? I read that; I wasn't sure how it was different to earlier studies done at Cambridge saying they thought Pfizer was still somewhat effective against SA strain, even if not as effective as against the original - great drop in the number of antibodies made, but still enough to prevent disease, or at least serious disease?

What new data?
