Here is the Pfizer clinical study from which they came up with the 95% efficacy if you want to follow along: https://www.nejm.org/doi/full/10.1056/nejmoa2034577

First, you might have heard your normie friends say "This vaccine is 95% effective. You should take it!"

Chances are, they dont really know what that means, but you can.

First lets ask the question "What do you think 95% efficacy means?"

Most people would answer "95% of the people will benefit from taking the vaccine, and stop them from getting infected". Lets see what it is.

This study (Phase 2 Pfizer clinical trial, which was the basis for the EUA) was conducted on 43,548 participants world wide. 21,720 of them received the vaccines. All data is reported 2 weeks after the second dose, up to 3.5 months.

In the placebo group 162 people out of 21,278 caught covid.

In the vaccine group 8 people out of 21,720 caught covid.

The test for COVID was done with what sounds like PCR test, but the exact words they use are "nucleic acid amplification–based testing (using a protocol-defined acceptable test)"

There is no reference to what protocol-defined acceptable test is, but my guess is they use 28 cycles for vaxxed and 40 cycles for placebo group. But no way to confirm this.

So even if we assume this is all authentic, the correct way to look at the data is: 162-8 = 154 people out of 21,270 actually benefited from the vaccine.

This works out to 0.7 % efficacy!

But they just ignore all the people who got the vaccine, and only consider the ones who fell sick. So out of 162 people, 154 people benefited from the vaccines - hence 95% efficacy.

If this is really the way they want to calculate this, then the number of participants for efficacy should only be 162+8 = 170 people. This means, a clinical trial focusing on only 170 people, not 43k people!

This is the big scam. They want to have their cake (43k participants) and eat it too (95% efficacy out of 170 people).

Either the efficacy is 0.7 % OR N=170 for efficacy.
