From the article itself:
Doctors in Norway have been told to conduct more thorough evaluations of very frail elderly patients in line to receive the Pfizer BioNTec vaccine against covid-19, following the deaths of 23 patients shortly after receiving the vaccine.
“It may be a coincidence, but we aren’t sure,” Steinar Madsen, medical director of the Norwegian Medicines Agency (NOMA), told
The BMJ. “There is no certain connection between these deaths and the vaccine.”
You present this as though something has been
proven, and it hasn't. It's in the "we need to check it out, but it could be nothing," category right now.
Very frail elderly patients die, and die all the time. I'll await what the further analysis shows any link or not. And note and note well, they state
very frail.
Addendum: There may be many who think that frail as used in medical literature is analogous to common usage, and it's really not. What many of us might consider frail doesn't even begin to encompass what it means when used in medical literature. For an abundance of references, see the results from:

You have to be quite medically compromised, and very often with many comorbidities, to be classed as frail. And if very gets stuck on in front of frail, the situation is far more dire.
