Given the timelines mentioned, vaccinated in mid July, got sick mid August, it looks like the peak effectiveness of the Pfizer vaccine after the second shot take 15-21 days to kick in. The virus can take up to 12 days before becoming sick/symptomatic. Rough math: (Aug 21) - (9 days sick) - (12 day incubation) = (~July 31 infection date). This would appear to fall in the time period of not yet being fully inoculated, if they were unlucky with the timelines.

They got unlucky, which sucks. I wish the best for the GP, but the important thing is that this anecdote doesn’t necessarily represent a breakthrough case. But even if it did, the Pfizer vaccine is 96% effective at protecting people, so 4% are still going to get sick. All of this is inline with all the data I’ve seen at least. For this particular case we don’t even need to discuss the recent data showing Pfizer (and possibly Moderna) dropping to 80ish% effectiveness after four-five months.

Literally all the data says people are safer getting vaccinated.
