I’m not a doctor, and I don’t play one on TV. I do have an advanced degree in mathematics/computer science.
There’s a significant misunderstanding about the statistics determined in lab trials. The stuff above doesn’t help.
I recommend reading this article about vaccine efficacy:
https://www.livescience.com/covid-19-vaccine-efficacy-explained.html
...in the New England Journal of Medicine, no less.
This is poor statistical analysis and is math used to advance an agenda. On its face it’s a bad vanity.
That being said all one has to do is look at Israel to determine population efficacy of the Pfizer vaccine. It is easy to spot.

I (budj) do have an advanced degree in mathematics/computer science.
Recommend me an article about computers and I’m interested. Otherwise, not so much.
From your link, what RansomNote says is spot on the same:
“What the 95% actually means is that vaccinated people had a 95% lower risk of getting COVID-19 compared with the control group participants, who weren’t vaccinated. In other words, vaccinated people in the Pfizer clinical trial were 20 times less likely than the control group to get COVID-19.”
Thank you for providing a link that explains vaccine efficacy.
