It’s not a lie, but it’s a completely meaningless number.
It’s called lying with statistics.
Using Pfizer’s figures, the relative risk reduction is 100(1 – (0.044/0.88)). Which is 95%. Voila!
This sounds fantastic and is a much better marketing strategy than reporting the absolute risk reduction. The absolute risk of developing COVID 19 symptoms without the vaccine is supposedly 0.88% and with the vaccine 0.044%. In absolute terms, the effectiveness of the vaccine is (0.88-0.044)%.
A risk reduction of 0.84%. Oh! A barely perceptible “efficacy.”
By using the relative instead of absolute risk reduction, the mainstream media (MSM) were free to market the mRNA vaccine for Pfizer and BioNTech (and other interested parties) with impressive sounding claims. These weren’t remotely truthful, not only because they relied upon statistical manipulation but because no one had a clue about BNT’s safety or efficacy. To this day, there are no clinical trial results.
