The RRR (Relative Risk Reduction) and NNV (Number Needed to Vaccinate)

[sd_shooter]

Must read especially for those who want to see some real data behind the vaccines:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8057721/

The interesting parts:

Although the RRR considers only participants who could benefit from the vaccine, the absolute risk reduction (ARR), which is the difference between attack rates with and without a vaccine, considers the whole population.

And....

ARR is also used to derive an estimate of vaccine effectiveness, which is the number needed to vaccinate (NNV) to prevent one more case of COVID-19 as 1/ARR

Let me clarify it for y'all:
- The purported RRR sounds great a first, 95% for some vaccines. But that value only matters for people who would benefit (ie. the ill, obsese and elderly)
- But when you look NNV, only about 1 out of 100 people would benefit
- And NNV measures what it would take to prevent just one CASE of covid, not a covid death

For every 100 people vaccinated, only one case of covid is prevented when vaccinating the entire population. Obviously we need not vaccinate everyone, it's likely causing more harm than good. Just vax the sick, elderly and the obese.

It's always curious when a placebo is just as effective (often even more!) than the concoction du jour.

It's always curious when a placebo is just as effective (often even more!) than the concoction du jour.

And that is basically what's going on here. The truth is the shot is just as effective as the placebo but people are either too lazy or ignorant to actually analyze the data. They just walk around and repeat the boob-tube mantra, "hurr-durr, 95% effective" not understanding that this number means relative risk reduction.
