What Does “95% Effectiveness” Really Mean?

The Highwire with Del Bigtree ( Bitchute) 

When it comes to Covid vaccines, what does "95% effective" really mean? Dr. Jim Meehan breaks down Relative Risk vs. Absolute Risk, and how Big Pharma manipulates the data on the absolute effectiveness of these vaccines (in this example is the Pfizer vaccine), which leads the media and public into a false sense of security.

Absolute Risk Reduction (ARR) has not been presented in outcome reporting. ARR is the difference between attack rates with and without a vaccine, considers the whole background population (21,724) = 0.76% ( less than 1% ) 

Only Relative Risk Reduction (RRR) has been presented for marketing purpose. RRR measures the ratio of attack rates with and without a vaccine-which is expressed as 1-RR ( 1 - 8/160 ) x100% = 95%

Another important matrix, Number Needed To Vaccinate (NNTV), has also been missing in outcome reporting.  This is another important factor in considering vaccine effectiveness. In this case, it means that 132 person have to be vaccinated in order to protect 1 person from infection = 1 person benefit against 132 who may not benefit or be protected from infection.  

The video closes with the question whether epidemiologic data is showing 95% effectiveness and paints quite a different picture that is emerging across different countries.
