Walgreens is testing population sizes every week which are similar in size to the Pfizer/BioNTech trial used to grant Emergency Use Authorization. Using the same Relative Risk Reduction efficacy calculation from the EUA, Walgreens real-world data shows the fully vaccinated / boosted are seeing a 37-42% negative efficacy rate when compared to the unvaccinated.

Misinterpreted. 21% of unjabbed they tested, tested positive. Still, other categories of jabbed tested positive at higher rates.
Ah, you're correct. Removing my post.
