According to Dr. Ron Brown, with the University of Waterloo, Ont. Canada, despite the fact that the FDA says that the Absolute Vaccine Efficacy should also be reported to the public, Big Pharma ignores this suggestion by only publishing the Relative Efficacy of their Vaccines. After following the simple mathematics below you will understand why Big Pharma prefers not to mention the Absolute Efficacy of their Vaccines.
Dr. Ron Brown explains in a video by 'TrialSite News Podcast' the difference between the Absolute and Relative Efficacy of Vaccines. Unfortunately, he makes reference to some figures, which are not shown in the video. While Dr. Brown takes great pain to be clear, a view of the figures he refers to would have been very helpful.
Not to worry, I have taken the time to interpret this portion of his talk, to make it clearer, since many of us are visual creatures.
Definitions:
An infection is an 'Event'
EER = Experimental Event Rate (the group receiving the vaccine).
CER = Control Event Rate (the group receiving the Placebo).
ARR = Absolute Risk Reduction (a real world number)
RRR = Relative Risk Reduction (a number to compare one study to another, or others)
To compare ARR to RRR, shown under definitions above, let us calculate the theoretical example from Dr. Brown's talk.
Here 200 volunteers got split into 2 groups of 100 each; group EER got the vaccine, while group CER got the placebo.
At the end of the trial, the Vaccine Group experienced one Event (1 infection in 100, or 1%), while the Placebo Group experienced two Events (2 infections in 100, or 2%).
First let us calculate the ARR, the Absolute Risk Reduction, as follows.
ARR = CER - EER
= 2% - 1%
= 1%
Therefore, the Absolute Risk Reduction is 1%
This result is the real world 'Efficacy' of this vaccine; this is the number Doctors, Patients and Government Agencies should work with.
Next we will calculate the RRR, Relative Risk Reduction, as follows.
RRR = EER/CER
=1%/2%
= 0.5, or 50%
Therefore, the Relative Risk Reduction is 50%
By reporting the Relative Risk Reduction (RRR) result, without showing also the Absolute Risk Reduction (ARR) result, they turned a 1% risk reduction into a perceived 50 % reduction, by failing to explain their spin.
As hinted at before above, the Relative Risk Reduction (RRR) number is a tool that researchers use to compare studies, and has little meaning in the real world of medicine, where the Absolute Risk Reduction (ARR) is the number of interest. While a 1% Absolute Risk Reduction is not a sexy as a 50% Relative Risk Reduction, the 1% represents reality, while the 50% does not.
Conclusion: We, the public, Doctors, and many Officials have no idea what the Absolute Risk Reductions are for these current vaccines, however, we know now for sure, they are not Efficacious in the range of 94% or 95%, whatever it is claimed, far from it. Our example showed an exaggeration by a factor of 50 times more or less is possible.
The video also shows that according to Dr. Brown, Dr. Fauci exaggerated the danger of Covid-19 by a factor of 10, based not on facts but on a desire to panic the people. It is not a far reach to think that panic among the population is good for the vaccine business.
Please read the comments to learn about the real Absolute Risk Reduction of the COVID-19 mRNA vaccines which ranges between 0.7% and 1.1%, depending on which vaccine you received.
